  Hi @PeterUK

  In this case, you can add the following policy route to avoid local out traffic have effect by Trunk.

  1) incoming=zywall, src=opt interface IP, dst=any, next hop type =interface, interface=OPT

  2) incoming=zywall, src=vlan443 interface IP, dst=any, next hop type =interface, interface=vlan443

  Hi @PeterUK

  In this case, is it normal if you type cli “Router> show ip route” at that time?

  I would like to check that if it is just only Web GUI display issue or not.

  Hi @PeterUK,

  It can be solved by adding policy route. We will evaluate and enhance it to avoid local out traffic being affected by wan trunk.

  Hi,

  i have exact this problem.

  i have tried to add the route as described. But i am not able to choose "any" Service and Source-port L2TP-UDP. i can only choose the service L2TP-UDP - is that right?

  Additional - what is behind L2TPVPNWAN - the Wan-IP?

  i have tried so ...

  

  ist hat right, or what is my mistake?

  I think Dienst is service you need to click show advanced settings to show the source port.
