Hello all,
I have a problem with remote access VPN on a ASA5505 (8.2).
I can establish a VPN connection and can ping the ASA, but nothing else on the network! Not only ping isn't working, I've also tried RDP, HTTP, and file access.
Additionally there is a site-to-site VPN to this ASA, which is working perfectly.
I have another ASA5505 which is almost configured the same and there it's working, so I really don't know where the problem is.
I hope you guys can help me!
Many thanks in advance!
Here's my config:

I note in your config that the pool of addresses for remote access VPN is a group of addresses included within the range of addresses on the inside interface. I have seen situations where this caused problems and so have a couple of suggestions:
- do the devices connected on the inside network have routes to the vpn pool of addresses?
- if you change the vpn address pool to use addresses that do not overlap with your inside network, does the behavior change?

Hello Rick,
I've changed the pool and guess what, it's working now!
Thanks a lot for your suggestion!
