Re: SNA OVER TCP/IP

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

Actually the Anynet trick should work. Anynet uses port 397 UDP and TCP
so if that's open you should be good to go. Once Anynet is up between
the boxes then STRPASTHR works fine. I have done this but we were not
dealing with blocked ports at the time.
