Hi,
We just installed a firewall 2 weeks ago at one
of our supported site and we had to ensure that tn3270
would work through the firewall and it surely does.
I had ported a copy of tn3270 to our HP-9000's and
I tested the connections with this 3270 everything
I was able to try worked.
There should be no reason anyone elses tn3270 client
wouldn't work.

take care
stevp
