Hi, Many libraries in North America now use a JAVA web interface to their library catalogues. 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? Typical link http://tplwpac.tpl.toronto.on.ca/ Regards Bob Cheeseman King Kommunications
