cannot map drives after VPN connection

Unanswered Question

Hi Guys,

After connecting over a remote access VPN on a 2811 I can ping the inside server but cannot map drives!

Do you guys shed some light as to why not as its this not helping at all without mapping network drives.

All,

Thanks for the replies.

I have resolved the issue, It was the returning traffic was being NAT'ed. When i PING any inside host I used to get reply from the outside interface/public IP and when I look at the "ip nat trans" table it was being NAT'ed. Amending the NAT access-list did not help on the router. Its such a blessing on the ASA with "NAT(0)" in this regard.

I created a loopback interface and a route-map. Route map routes the selective VPN traffic from inside to loopback and then normal routing from loopback to outside hence overcoming the NAT thing. This works for me.

Do you guys have any other way of doing this???

Config below:
