Hi all. We have 2 ZyWall USG 1100. Configure ipsec vpn. On 1st lan 172.20.0.0/20, 2nd 172.20.16.0/21. Clients work fine, but zywalls don't see vpn lan. How i can fix it?

Sorry for incomplete question. Problem was ZyWalls don't see lan behind vpn. Computers works between lan. I forgot add policy route for ZyWalls via vpn gate(

"Clients work fine, but zywalls don't see vpn lan" can you explain more detail?

Just curious what do you mean " Clients work fine, but zywalls don't see vpn lan"?? Is that client can access network but VPN cannot established?
You can check the example of configuration of VPN from FAQ.
