Next Hop: VPN Tunnel Flex 100H

I am looking to upgrade my home VPNs from Zywall USG 110s to Flex XXXH(P) - I had upgraded one of them this summer - and realized that I could not define a VPN tunnel as a next hop. Zyxel Customer Service then replied to a message that would be a feature supported in the October firmware - it does not seem to exist in the 1.3 release however either. What I am trying to support is this: I have SSIDs (VLANS) in each home that represent a specific country - so SSID.NET would be US, SSID.AT for Austria, SSID.ID for Indonesia and SSID.IN for India. So if you were for example on SSID.AT in a home in the US, the traffic would be routed to a home in Austria and go on the public internet there. Truthfully mainly used for streaming content - but it's sometimes useful for specific country content.

Questions:

1, Did I miss anything in 1.3 (running on a Flex 100H) where that feature has been added.

2, If it has been dropped from 1.3 - when is it coming now?

3, Is there another way to accomplish what I am trying to do

    Hi @amateur_netops

    Due to changes in the product roadmap, there was no feature enabling VPN tunnels as next-hop with firmware version 1.30 for H series firewalls.

    We are still evaluating this feature. When it becomes available, we will make an official announcement in the Firewall News & Releases section. Please follow this section to stay updated on new features and enhancements.

    For your scenario, we can suggest following the guide to configure Site-to-Site VPN between ZLD (USG, USG FLEX) and uOS (USG FLEX H) using Route-based VPN.

    Please let us know if we can be of any help.

    Hmm - disappointing that the feature has not been added as previously stated by Zyxel support - it is the only reason I bought another Flex H for another home.

    I don't see how the guide helps me since traffic to the internet will not go through the tunnel.

    Here is a simplified scenario:

    Site A has two networks - 192.168.100.X and 192.168.101.X

    Site B has two networks - 192.168.110.X and 192.168.111.X

    Devices on 192.168.100.X and 192.168.110.X need to communicate together - OK - Site to Site deals with that just fine

    Devices on 192.168.101.X should use the public internet on Site B

    Devices on 192.168.111.X should use the public internet on Site A

    A site to site doesn't do much here - in my old configuration - all traffic from 192.168.101.X would be sent to 192.168.110.X - where all traffic from 101.X would go to WAN - and all traffic for 101.X would be forced back into the VPN from 110.X-101.X

    How does a site to site without an ability to force traffic there help me?

    Hi @amateur_netops ,

    As of now, you can establish a Route-based VPN (VTI) by following the instructions in the article above. Once configured, follow these steps to add policy routes to adapt your requirement.

    Site A: LAN = 192.168.101.X/24

    Need to create one policy route to force redirect traffic to site B from site A.

    src = 192.168.101.X

    dst = any

    next hop = VPN => Choose Tunnel name

    Site B: LAN = 192.168.111.x/24

    Need to create two policy routes:

    Policy route 1: is for SNAT to Internet when the source is site A subnet 101.X

    src=192.168.101.X

    dst = any

    next hop = WAN1 or WAN2

    SNAT = outgoing interface

    Policy route 2: is for routing back the subnet 101.x traffic from Internet.

    src = any

    dst = 192.168.101.X

    next hop= VPN => Choose Tunnel name

    SNAT => None

    But there is no next hop=VPN - that was what I as whining about and was initially told we would get in October.

    The options on the Flex are: Auto, Interface, gateway,, gateway-ip and trunk - VPN is not an option

    Hi @amateur_netops ,

    As we mentioned above, you can establish a Route-based VPN (VTI) by following the instructions in this article, and then you can see the VPN option in Interface next-hop type.

    Here is the screenshot of the H series:

    OK - got this to work - thank you. I had to delete the other connections between other subnets on those sites and also manually route them. Then I had to change MTU to 1300 on the WAN port since tracert would work but http or https did not - somewhat odd - and a little slower than I would have expected. But got it working now

    Oh - is there a way to rename those vti-wizzard something things to something more meaningful. Will be a pain to keep track if I have several

    Hi @amateur_netops ,

    Under the current uOS design, VTI interface names cannot be modified. However, we have implemented a description field in both the interface and static route configurations that allows users to add custom identifiers for easier reference.
