First of all, I'm on V3R7M0.

I'm trying to set up my AS/400 so that it can "see" the internet.  I
already have 2 NT servers talking to the internet with no problem.  I
also have my AS/400 talking to my NT servers on a private sub network no

I have my AS/400 set up with with a netmask of and the NT servers on the same subnet, and they talk

Now, I have my NT servers on the internet, IP range of x.x.x.112 to 140,

and am on the 'net.

I tried the same with my AS/400, I added tcp/ip interface x.x.x.139,

the same internet
machine from my NT machine, where it worked, and my AS/400, where it

Is there something I'm missing here?  What is the piece of the puzzle
that is different
