3COM ADSL Firewall ROuter Config

I am having difficulty in configering a 3CRWE754G72-A, it could be i
am misunderstanding how the unit passes the IP addresses.......

My ISP has assigned a public IP address, normally the 3Com Router
would hide this address from my local LAN...In my case to enable my
VPN connection to work, i need this public IP address to be passed
through the router and avialable at on of the Ports ???..

I have tried disabeling the NAT function in the hope of passing though
the IP address, this seems to have little / no effect as the Local IP
address is still reconized.....

Im i misunderstanding something ??

You sure? What VPN client is it?

If it only uses TCP/UDP traffic and you know which ports it requires, then
the 'Virtual Servers' section of the Firewall config may help.

If you really need to get it working, the nuclear option would be to specify
your LAN IP address in the DMZ section - your VPN should then work but
you'll have _no_ protection from the outside world.
