I just posted a question yesterday that was answered quickly. Thanks.
I have the VPN up and running now except for one problem. Users trying to connect over cellular modems (Dell Mobile Wireless on AT&T) get connected but then cannot get anywhere, either external or internal.
I have verified this with myself and another user. If I use the cellular card I get connected then I can't access anything (no ping, no http, no telnet). If I disconnect and connect either over a wired or wi-fi lan connection it works...I can access internal services on the remote lan.
Another thing is I can access a VPN 3005 Concentrator over the cellular modem and it works fine.
This situation seems pretty strange. Can anyone help or shed some light?
I added crypto isakmp nat-traversal 10 to the config. Still doesn't work. I'm leaning more towards this being an issue with the drivers from Dell as I have been able to connect and have the VPN function as it should from a wired or wi-fi connection.
The only thing that goes against that is I can connect to 2 different 3005 concentrators over the cellular modem and it works fine.
I notice when I connect to the ASA if I do an IPCONFIG/ALL I have default gateways on both the cellular (PPP) connection and the Virtual adapter connection. Shouldn't I only have one gateway which would be the one associated with the Cisco Virtual Adapter (the gateway is my ip address, as it should be).
