Issue with Verizon Aircards passing traffic past VPN 3005

Unanswered Question
Apr 23rd, 2007

We have a Cisco VPN 3005 as our endpoint. Clients connection using the Cisco 4.7 client. Currently here is the basic config on the device:

Pub Interface 65.xxx.xxx.xxx

Private Interface 172.22.0.3/16

VPN Addy Pool 172.31.1.0/28

Static routing is used to route traffic as necessary.

Clients can connect via wireless broadband or broadband and ping past the VPN Private interface and open up Outlook using an online exhcange profile. But clients connecting over an EVDO or 3G cellular modem cannot open Outlook. They can ping by IP but not DNS.

I have tried using different transports ie , IPSEC/UDP , IPSEC/TCP , and straight IPSEC. No joy. All the clients have allow local LAN access checked and the VPN Group is set to tunnel traffic in that network only. Any clues??

I have this problem too.

Issue has been resolved. Clearing DNS with an ipconfig /flushdns , ipconfig /registerdns while on aircards on VPN resolved it.
