I am using the cisco VPN client to access a 506e. Everything works just fine when accessing the network from home. However, after I establish a tunnel from behind another PIX on some other business network, I can not ping any servers or IPs inside my office. any help?
 
You need to implement NAT-Traversal on both sides of the tunnel. This will allow IPSec over UDP, which is necessary for VPNs from behind NATed or PATed addresses.

It's necessary if you're using PAT-ed addresses. It is not necessary behind static NAT.
