if the device is nat-t aware nating shouldn't be any problem for ipsec vpn. Check with customer support if ZyWALL supports nat-t, window xp native ipsec client supports NAT-T .

You are using private IP addresses which will cause problems with IPSec.Regards Kim Guldberg CPSA, GCFW Diarmaid McManus skrev:Dear list, I'm working for a company that recently purchased a ZyWALL 5 for a client. There are problems setting up a VPN, however, o the internal network. We are attempting to set up the ZyWALL to test the VPNs compatibility with the Windows VPN client inbuilt with XP Pro. We have it set up as follows(apologies if there's a lack of clarity...): -------- 192.168.1.5 -> ZyWall WAN port(.1.1) -> ZyWall LAN port(.10.223) -> network -> 192.168.10.222 -------- 192.168.10.222 is the client we are attempting to connect from, to add .1.5 to the virtual network. I have tried various configuration settings, both on .10.222 and the ZyWALL, but to no avail. I have read and re-read the instructions for adding a VPN and it turns out the same no matter what values I add. Can anyone, from the sparse information provided, tell me anything I may be doing wrong? With regards to ports etc. Is the Windows VPN client compatible with ZyWALL? Are there any other free clients compatible? Much thanks in advance, ~Diarmaid McManus
