Hi 

Thanks for the replies

Basically I tried the NAT command but it wouldn't work, I think the
destination server 192.168.1.2 is talking back to the client directly
as opposed to going back to the 192.168.1.1 originating server then to
the client.

Would you which package contains ipnatctl, as I typed it on the
command line but its not there?

Thanks
Shaz
