Hello all,
I've been searching all day for a solution to this problem. I setup and SSL anyconnect VPN on my Cisco ASA 5505. It works well and connects with out a problem. However, I can't ping any internal clients, but I can RDP to them. It may be something simple and I would appreciate any help. Most of the time people end up posting their config so I will as well.

Your config actually looks good (you have the ACL that would allow the echo-reply back since you don't have inspection turned on) - are you sure this isn't a windows firewall issue on the PCs? I'd try pinging a router or switch just to make sure.

Hi Jason,
Thanks for the reply, would that acl be applied on the outside interface coming in? I guess I'm not exactly sure what interface or if the VPN terminates on a specific interface.
Best Regards!

I also tried pinging a switch and client and neither worked. I can ping from the client to the VPN users though and I can ping between clients internally.
