Hi,
Im trying to configure a 1841 router with a 3G WIC and connect it back to our VPN concentrator.
I have followed this document on configuring the WIC:
http://www.cisco.com/en/US/docs/routers/access/1800/1861/software/feature/guide/3ghwic.html
and added into the config the correct settings for our point-to-point VPN.
Im pleased to say that it all works, the WIC card connects to 3g, the VPN connects back to the concentrator but when I try and ping a computer over the VPN from a computer connected on the Fa0/0 port, I dont get any responce, its almost like the packets arn't being routed over the VPN link properly.
If anyone can suggest why I can get a VPN connection but I am unable to ping across it please let me know.
The routing rules are correct on the local Lan side as we have lots of other remote sites connecting using standard ezvpn over ADSL lines.
I have attached the config I am using.
Thanks in advance!

Hi ,
Do you have nat in your router at all?

How does your concentrator learn the routes to the network in your location where you try to ping from? From what I know from EZVPN (which is admittedly not an awful lot), you need to specify the routes to be learned by the concentrator using e.g.:
crypto ipsec client ezvpn northern
acl inside_networks
ip access-list extended inside_networks
permit ip xxxx
where xxxx is the network connected to the Fa0/0 port (or any additional cascaded networks).
There are other ways to advertize the routes to the concentrator, but I do not see any routing configuration in your setup?
HTH, Thomas
