Cisco VPN Clients cant communicate with each other??

Hi everyone,

I have a Cisco 1721 configured for VPN clients. All works fine. I'm interested it using the clients for soft phones off of a PABX. However, the clients can’t see each other?? I can’t ping between them.

Otherwise the clients operate absolutely fine. I need client-client communication for the voice direct RTP.

Tried looking at the natting and I temporarily removed all the acls as a precaution... No good.. :(

Any ideas? I noticed there is a global command to enable this feature on a VPN concentrator. Is there an equivalent for routers? I can use CLI or SDM.

500 points for this one..

Many thanks! :)

Correct. The VPN client has a built in firewall that prevents you from pinging them.
The VPN client was designed to work with the VPN concentrator and the concentrator can send configuration information to the client with specific firewall rules, etc. IOS and PIX only work at the most basic levels with the client and do not "push" firewall configurations to the client.

Ahhhh!... I'd forgotten about that. I've tested it and I can ping between clients now... Just need to test it with voice :).

Thanks Irmoore. You're a legend..
