New to Zscaler. Introduction to Traffic Forwarding - Zscaler This issue is seen in Cisco IOS XE Release 17.9.1a or Cisco IOS XE Release 17.9.2a. This process is because the prefix is longer than 0.0.0.0/0 and doesn't fall within the address prefixes of any other routes. It cannot contain spaces or any other characters. This interface should be the egress interface and is typically the internet-facing faster retry interval, which is the number of seconds between DPD retries if the DPD message is missed by the peer. and manage multiple domains or logically separate network segments from a particular dashboard. For Cisco IOS XE SD-WAN devices, INTERFACE is the only supported Source Type. How can you keep your entire solution simple, with the various locations (including hybrid and multi-cloud environments), users, and resources forwarding traffic to the Security Service Edge? Chapter 3: Delving into ZIA Policy Features - Zscaler Cloud Security This field is mandatory and can contain only uppercase and lowercase letters, the digits 0 through 9, hyphens (-), and underscores The key is to find the right fit for the use case at hand. (From Cisco vManage Release 20.9.1) Cisco vManage automatically chooses the applicable global Cisco SIG Credentials feature template based on the Cisco SIG feature template configuration. In Cisco vManage Release 20.7.1 and earlier releases, Device Templates is called Device. When you create a route with the virtual appliance hop type, you also specify a next hop IP address. Zscaler supports the multiple traffic forwarding mechanisms, Depending on your environment and requirements, you can choose one or a combination of the following traffic forwarding methods Zscaler recommends that you use a combination of tunneling, PAC files, Zscaler Cloud Connector, and Zscaler Client Connector (formerly Zscaler App or Z App) to forward traffic to the Zscaler [] yet created the template. Secure Your Workloads Build and run secure cloud apps, enable zero trust cloud connectivity, and protect workloads from data center to cloud. device didnt clear the previous tunnels after becoming operational again. 5. the Secure Internet Gateway feature. Click Device, and click and choose Edit for the device template that you want to configure. as cloud security services. Work within your limitations. Route propagation shouldn't be disabled on the GatewaySubnet. You can currently create 25 or less routes with service tags in each route table. you can create an active-active setup. lab This feature allows you to use the SIG template to steer application traffic to Cisco Umbrella or a Third party SIG Provider. The file is downloaded to your browser's default download location. Specify the API URL for the SIG endpoint of the tunnel. We recommend that you use the default configuration. See DMZ between Azure and your on-premises datacenter for implementation details when using virtual network gateways between the Internet and Azure. that tunnel has higher priority for traffic flow. In the Available Devices column, choose a group and search for one or more devices, choose a device from the list, or click Select All. Look at the Traffic Forwarding options available to you on our help portal. (_). This feature is supported for both DNS security policy and SIG templates. From the Additional Cisco VPN 0 Templates list, choose the Cisco VPN Interface GRE template. You can use user-defined routes for forcing traffic from the Express Route to, for example, a Network Virtual Appliance. Applicable releases: Cisco vManage Release 20.8.x and earlier releases. Secure Internet Gateway (SIG). multi-path (ECMP) distribution, or assign different weights to the active tunnels so that some tunnels carry more traffic To attach one or more devices to the device template: Click Device Templates, and choose the template that you created. The tracker calculates the round-trip time (RTT) and compares or more active tunnels are provisioned, the traffic toward the SIG is distributed among these tunnels, increasing the available By provisioning a back-up tunnel for each active tunnel, you can create an active-back-up Click Filter and configure the following: Choose one or more of Critical, Major, and Minor. To designate a back-up tunnel, choose a tunnel that connects to the secondary data center. The only slight difference from the Option B method is that two labels are used when forwarding traffic between the ASBRs (Step 3): the VPN and LDP labels (as in a normal forwarding situation within an AS). How does the traffic from your users, applications, and offices reach the Service Edge platform? By default, the MSS is dynamically adjusted based on the interface If you've not configured Umbrella credentials, Cisco vManage prompts you to configure the credentials: Click here to add Umbrella credentials. Traffic to the service doesn't route to the next hop type in a route with the 0.0.0.0/0 address prefix. By default, a tunnel created using the SIG template pushes the tunnel vrf multiplexing command. Zscaler deployment guide - Insider tips for deploying Zscaler Choose the type of device for which you are creating the template. applicable global SIG Credentials template to the device template. For a software release earlier than Cisco IOS XE Release 17.4.1, Cisco vManage Release 20.4.1, see Configuring a GRE Tunnel or IPsec Tunnel from Cisco vManage. Use a device-specific value for the parameter. For device-specific parameters, you cannot enter a value in the feature template. Monitor the status of automatic SIG tunnels using the following Cisco vManage GUI components: SIG Tunnel Status pane on the Monitor > Security page, SIG Tunnels dashboard on the Monitor > Tunnels page. In this video we have discussed about various Traffic forwarding methods to forward the traffic to Zscaler cloud Show more APP Profile & Forwarding Profile in Zscaler Client connector. Remove any existing static IPv4 routes to the internet: Under IPv4 Static Route, find any routes to the internet and click the delete icon to remove it. Exploring ZCC internet traffic forwarding. with weight configured as 20, then the traffic is load-balanced between the tunnels in a 10:20 ratio. Cisco vManage displays event information for the modified time range. cisco ise In previous releases, in certain situations, the control and data packets may be routed to the SIG endpoint through different For more information, see Action Parameters in the Policies Configuration Guide. Cisco VPN feature template. In the Description field, enter a description for the device template. Subscription confirmed. On your premises, you might have a device that inspects the traffic and determines whether to forward or drop the traffic. To view Cisco Umbrella SIG tunnel events, search for events that have ftm-tunnel in the event name. The tunnel health is monitored as follows: Based on the configuration in the System feature template, Cisco vManage creates a tracker according to the default or customized The routes override the ID4 and ID5 routes for traffic leaving Subnet1. Cisco vManage of the failure. In Basic Configuration, configure parameters as desired. among the tunnels. Destination Data Center: SIG provider data center to which the tunnel is connected. In this video you will review the common methods to forward traffic to Zscaler for inspection including: - Zscaler Client Connector - GRE or IPSec Tunnels - PAC Files 2023 powered by The tracker monitors the health of the tunnel using HTTP probes. Specify the maximum MTU size of packets on the interface. Events: Number of events related to the tunnel set up, interface state change, and tracker notifications. The description can be up to 2048 characters and can contain only alphanumeric Automatic IPSec tunnels: Cisco vManage automatically selects the secondary data center closest to the WAN edge device. If you assign any of the previous address ranges within the address space of a virtual network, Azure automatically changes the next hop type for the route from None to Virtual network. Azure automatically routes traffic between subnets using the routes created for each address range. This field is mandatory, and it can contain any characters and spaces. If the appliance needs to route traffic to a public IP address, it must either proxy the traffic or perform network address translation (NAT) from the source's private IP address to its own private IP address. Enter a Prefix (for example, 10.0.0.0/8). This causes your feature templates to fail when connecting to SIG services or other external services such In travel, you may have special requirements during your journey. The next hop types aren't added to route tables that are associated to virtual network subnets created through the classic deployment model. Perform these actions to configure a device template for the IPsec interface. To update the credentials configured in Cisco vManage Release 20.8.x or an earlier For details, see Azure limits. The state of this route is still Active for all other subnets within both virtual networks, because the route isn't associated to any other subnets within any other virtual networks. A virtual network gateway was created to meet requirement 2. The information is displayed in a bar chart. Obtain the recommend list of Zscaler data centers through a GET API request for /vips/recommendedList. These range from GRE and IPSec tunnels to PAC file forwarding; and using the Zscaler Client Connector and/or the Cloud Connector. Choose the Cisco VPN Interface GRE template from the group of VPN templates. and deploy the configuration to redirect traffic to SIG endpoints. window It cannot contain spaces or any other characters. The CiscoVPN Interface GRE template is no longer used to configure a tunnel to a SIG. By provisioning two or more active tunnels and distributing the traffic among them, while not provisioning any back-up tunnels, The following is a sample output of the show sdwan secure-internet-gateway zscaler tunnels command for automatic IPSec tunnels: The following is a sample output of the show sdwan secure-internet-gateway zscaler tunnels command for automatic GRE tunnels: Minimum supported release: Cisco IOS XE Release 17.9.1a. Nov. 20, 2013, 3:45 PM PST. However, you can also create customized trackers with failover parameter values that suit your SLA requirements. Cisco vManage automatically selects the secondary data center closest to the WAN edge device. Stay agile and stay flexible with the methods available. cyber security (Read only) Global credentials for Zscaler. The route table this route exists in isn't associated to Subnet2, so doesn't appear in the route table for Subnet2. 1. Cisco vManage automatically selects the secondary data center closest to the WAN edge device. Automatic IPSec tunnels: Cisco vManage automatically selects the primary data center closest to the WAN edge device. More than 90% of traffic directed to the internet is over SSL connection and is therefore encrypted by default. Whenever a virtual network is created, Azure automatically creates the following default system routes for each subnet within the virtual network: The next hop types listed in the previous table represent how Azure routes traffic destined for the address prefix listed. Click the delete icon on any existing IPv4 route to the internet. Click, and in the Add Umbrella Credentials dialog box, enter the details mentioned in Table 2 and click Add. Depending on which feature template you want to update, do one of the following: From the Application drop-down menu, choose Secure Internet Gateway. The Cisco SD-WAN Umbrella for SIG support security policy requirements for different sub-regions of their SD-WAN network. SIG Credentials template. Alternatively, an ExpressRoute connection could be used, but in this example, a VPN connection is used. In the Azure portal, on the Zscaler zscloud application integration page, find the Manage section and select single sign-on. Configuring Proxy Chaining | Zscaler Trackers help failover traffic If you have attached the Cisco VPN Interface IPSec feature template to the same device, ensure that the interface number you Just like your travel plans will depend on the destination of your journey, your traffic forwarding choice must depend on the resource being accessed. to the device. For more information, see Management and Provisioning > Getting Started > Overview in the Cloud Security API documentation on the Cisco DevNet portal. In the case of manually created tunnels, create and attach the tracker. the URL in question). The routes aren't associated to Subnet2, so the routes don't appear in the route table for Subnet2. You have made the decision to implement zero trust security for your organization. It's a quick and easy way to forward your traffic to the Zscaler service for evaluation purposes and to add an additional layer of security to your network. Deploying the virtual appliance to the same subnet then applying a route table to the subnet that routes traffic through the virtual appliance can result in routing loops where traffic never leaves the subnet. A location may not have a static IP address available for establishing a GRE connection. The setting disables Azure's check of the source and destination for a network interface. Therefore, in most cases for accessing the internet or SaaS applications, a GRE tunnel or similar non-encrypted tunnel forwarding mechanism will suffice to get the traffic to the Service Edge that is closest to the source. Enter the name of the source interface of the tunnel. Copyright Techclick 2023. If the destination address is for one of Azure's services, Azure routes the traffic directly to the service over Azure's backbone network, rather than routing the traffic to the Internet. Automatic IPSec Tunnels: From Cisco IOS XE Release 17.5.1a In earlier releases, the Layer 7 Health Check feature is only available if you use VPN Interface From Cisco IOS XE Release 17.4.1, Cisco vManage Release 20.4.1, all SIG related workflows for Automatic and Manual Tunnels have been consolidated into the SIG Alternatively, you can also redirect traffic to SIG using Data Policy. The device updates the routes for any service VPNs that are connected to the tunnel. If agent-based mechanisms are not possible to implement, PAC file-based forwarding could be an option. Public IP address of the tunnel source interface that is required to create the GRE tunnel to Zscaler. If you wish to route traffic Monitor security events related to automatic SIG tunnels using the Security Events pane on the Monitor > Security page, and the Events dashboard on the Monitor > Logs page. Secure Internet Gateway. IPSec Tunnel Creation Improvements in an Active-Active Setup: This feature ensures that when you provision an IPSec tunnel, the control and data traffic are sent through the same the achieve Equal-cost multi-path (ECMP) routing. Zscaler based on geographical proximity to the device. routed to the SIG through only one of the active tunnels. ID9: Azure added this route when a user-defined route for the 10.10.0.0/16 address prefix was added to the route table associated to Subnet1. Be able to network address translate and forward, or proxy the traffic to the destination resource in the subnet, and return the traffic back to the Internet. Forescout The destination depends on whether you specify a network virtual appliance or virtual network gateway in the custom route. To learn about the maximum number of routes you can add to a route table and the maximum number of user-defined route tables you can create per Azure subscription, see Azure limits. The ID6 and ID7 routes exist to meet requirement 3 to drop traffic destined to the other virtual network. For example, if you see None listed as the Next hop IP address with a Next hop type of Virtual network gateway or Virtual appliance, it may be because the device isn't running, or isn't fully configured.
