Cisco VPN client 4.x behind PIX 501 connecting to a PIX 501 VPN server


I have set up a Cisco PIX 501 as a VPN server. When I connect to it with the Cisco VPN client software from a public IP, everything works fine:

WinXP with Cisco client --> ADSL Modem (bridge enabled)  --->  INTERNET  ---> ADSL Modem  ---> PIX 501 VPN server  ---> Windows server

I can ping and reach the remote server throug RDP.

When I want to connect to the PIX501 VPN server from behind a default PIX501, the connection is made, but the remote local LAN is not reachable. I cannot ping or reach the server in anyway.

WinXP with Cisco client --> local PIX 501 (default settings)---> ADSL Modem (bridge enabled)  ---> INTERNET  ---> ADSL Modem  ---> remote PIX 501 (VPN server)  ---> Windows server

What do I have to set up in the local PIX 501?

2 - Assuming #1 is not an issue, be sure to enable nat-traversal on both 501's:
