Windows 2003 as Vpn Server, problem of NAT.

Hi Pro, first this is my network config

(me at home)---------------internet --------------company=[207.*]
Cisco PIX[10.128.*] --------------------[10.128.*]Windows server 2003
(VPN server) [192.168.140.* and 32.0.0.2] -------------------------
[32.0.1.1]IBM VPN BOX ----------------------------------------IBM
system-dev server:32.0.2.1


im connected from home via vpn to my company, the vpn server give me a
192.168.140* ip address.
Everything works great, i can ping/connect to any machines in
192.168.140.*.
Now... i need to connect to a 32.0.2.* machines on the IBM side of the
second vpn...
but the problem is... the IBM VPN BOX refuse other source ip address
that 32.0.0.*

i know...i should probably NAT my 192.168.140 addresses to 32.0.0.
