For some reason I recently am having an issue pinging or ssh to systems behind a vpn connection. This issue only occurs when I connect on the Mac (OS X 10.5). On Linux and Windows it works fine.

I will get the following after making a VPN connection via the cisco vpn client v4.9

ping: sendto: Cannot allocate memory

I get a similar error when trying to ssh to a server.

I have noticed that after connecting, ifconfig -a does not show the assigned address the vpn appliance ASA will provide the client.

This issue only occurs after connecting to a VPN. I tried restarting the vpn clients sub-system, no go. I installed and ran applejack, still no go.

Is there a way to rebuild the tcp/ip stack in a MAC if this is the only solution available?

Any ideas?

Thanks,
