[plug] vpn breaks home network

I have a little home network with a ASDL2+ modem, a hub and
two computers with IP addresses 192.168.1.100 (plastic)
and 192.168.1.13 (lycra)
It all works well until I start up cisco vpn on plastic. The vpn
works but I can not see lycra any more.
I think what I need is a "VPN pass-through" on the modem. Does this
The vpn gives the following information when it starts up.
Client address: 18.104.22.168
Server address: 22.214.171.124
Encryption: 256-bit AES
IP Compression: None
NAT passthrough is active on port UDP 10000
Local LAN Access is disabled
The modem (iconnectAccess621) has an IP Forwarding menu
that has VPN with IPSEC L2TP -- which (if I understand it)
sets up the following
Protocol PortStart PortEnd PortMap
UDP 500 500 500
ESP * * *
UDP 4500 4500 4500
turning this on doesn't fix the problem. Perhaps because the
vpn is expecting "NAT passthrough" on "port UDP 10000"?
I have tried to set this up as a "Custom Port Forwarding" with
Source IP 126.96.36.199
Destination IP 188.8.131.52
Port Start 10000
Port End 10000
Port Map 10000
but I am really just guessing here. Is the "source" the server at work
or the modem or what?
any pointers received gratefully!
