Hi,

i set up an EZ-VPN but once i connected i cannot ping my internal lan behind the router.

192.168.1.x -> VPN Client IP's
192.168.0.0 -> Internal Lan via Vlan10 interface to switch
Dialer -> internet connection

I cant ping 192.168.0.2 but i can ping 192.168.0.30. I found out that 192.168.0.2 does not send the packets back to the VPN client i guess.
But i can ping the 192.168.0.2 from the VPN Router if i logged into it.

Here is my config:
