VPN works with cable but not via wireless

Unanswered Question

I use the Cisco Systems VPN Client Version and a ZyXEL Prestige 660HW-61 adsl modem/firewall/router together with two ZyXEL G-570S set up as AP+repeater(s).

When connecting directly to the router via cable, the VPN works fine, but when i connect via wireless, it seems to connect but i cannot access anything via the VPN.

I configured it (the VPN client) to log messages and have attached the resulting file here.

Any help with figuring out what this means and suggestions on how to resolve the issue is highly appreciated !

Hi Michael

Make sure the following command exists in VPN endpoint that you connect via VPN client to.

Also make sure your wireless router supports transparent tunneling (called vpn passthrough in some routers) and enabled

Hi husycisco,

I'm not sure, but i have a feeling you were also going to copy/paste some commands ?

Also, i will check that my router supports transparent tunneling, but would it work via cable if that was not the case ?

Best Regards,
