We have a PIX 515E UR firewall in place on our network. We're trying to configure the VPN feature. I can connect to the PIX fine using the 3.6.4 VPN client, but once I'm connected, I cannot ping anything except for the (PIX) VPN endpoint address. The VPN client software is showing the following routes and it appears that all packets are being encrypted properly. I assume this is a NAT and or routing problem, but I don't know how to fix it.
The VPN client is assigned a 10.0.254.x address. I want that client to be able to access machines on the 10.0.0.x 255.255.255.240 network.
VPN Client Routes:
10.0.0.0 255.255.255.240
x.x.x.x 255.255.255.255

Your nat 0 statement is wrong - you want to add the inside netblock to it so that reply traffic from the inside segment does not get natted to vpn users.
adding:
access-list 100 permit ip 192.168.1.0 255.255.255.0 10.0.254.0 255.255.255.128
should do the trick.

No, I don't want VPN access to the inside interface (192.168.1.x). I want VPN access to the ATI interface (10.0.0.0/28). I already have the following in there:
access-list 100 permit ip 10.0.0.0 255.255.255.240 10.0.254.0 255.255.255.128
