After replacing an older BM server with a new BM3.7 server, My
experiences the following problem:

1) customer opens a telnet session to an AS400 host through the BM3.7
2) after a random amount of time anywhere from 20 minutes to an hour,
session disconnects

If I have the workstation bypass the BM3.7 box and sit on the "Public"
of the firewall, the AS400 session will stay open indefenitely!

The BM3.7 box is performing dynamic/statics NATs, just like the
previous BM
did. I've also tried using the telnet proxy and still experience the
disconnects. The BM3.7 box is up to date with patches and is running
a very
basic configuration as was the older BM box.
