Hi Bob, I have tried the link from Belgium and it doesn't work either. With a network monitor I see indeed an outgoing TCP request towards port 5050, but the other site reject the connection with a RST. So, maybe your protocol definition is correct but there is a problem with the site...

It is from Dynix and called WebPAC. It uses port 5050. I have defined a protocol definition (obviously incorrectly) and opened it under ISA but still seem unable to connect (I receive an "error connecting to server message"). I was wondering if someone has a solution for this?
