Following Brano's excellent guide on how to setup an L2TP VPN on a ZyWALL USG, my clients are able to successfully connect and access all machines on our subnet. :D
Unfortunately for this to work the Send all traffic over VPN connection feature must be checked on the client as the L2TP pool (i.e. 10.0.6.0/24) is obviously not part of the local network (i.e. 10.0.7.0/24). Changing the L2TP pool to an address range (e.g. 10.0.7.200 to 10.0.7.219) seems to be the wrong approach as no traffic is ever coming back through the VPN connection.
This is a ZyWALL USG 50 with firmware version 3.30(BDS.5).
It's important that the client's internet traffic does not flow through the ZyWALL while the VPN connection is active. I would be very grateful for any help.
