[ale] IP routing problem.

[mims at gomwi.com (Millard Wayne, An Infocure Company)]

Hello all.

I have another networking problem I was hoping for some help with.  I
have gotten some really good answers here before.  For that I say Thank
You.

Here is my latest dilemma.

I have a Linux box connected to a dedicated ISP account with a static IP
address.  I have IP masq on this box for the internal network and
everyone can get out, no problem.

The problem is I have an AS/400 inside the network that I need users on
the internet to be able to connect to.  Is this possible?  Is there
someway to route an IP or a group of IP's from the internet through the
Linux box and directly to the AS/400 so that the PC's think they are
attaching directly to the AS/400? Or am I just dreaming?

I hope this isn't to off subject.

Thanks in Advance,
Tory
