Cisco ASA – Remote access VPN user’s can’t connect to internal resources on the same network

Jason Tramer Jason Tramer Profile: Jason Tramer

So I was working with a Cisco ASA 5510. The inside network was I had created a  remote access vpn policy for users and set them up to receive address’s on their inside network (

While the users we able to connect fine to the vpn they were not able to ping or access any resources on the internal network. The reason I found for this is that even though they are receiving address’s on the same network as the internal LAN, the ASA still considers them part of a separate network and will try to NAT the traffic using your dynamic NAT rule.

The way to resolve this is to create a NAT exemption rule from your inside network to your inside network. Sounds funny, but it works.

Hope this helps

    Wow..what an unusual problem with a likewise unusual solution. I have been suing [A href=""]PC remote access[/A] tools for years now and never had an issue like this. But, if I do, I know what to try first!
