2621 router and VPN

[rtfm2002]

Hey guys, I have the following:
============================================================

Problem: When I connect though the cable modem using a 2621 router, I can authenticate to my cisco vpn concentrator at work and then to my local homeoffice lan. However, I can't seem to ping anything on the network at the homeoffice even tho I do get an IP address. Do I have to specify ipsec to pass though the 2621 router? Here is my basic current config.
============================================================
