Hi all, In our lab, we're testing ISA server. We try to use web publishing, it seems to work except when a client (supposed to come from the Internet) connects to ISA with port 1723 (client side) on port 80 (server side). In this case, the TCP packet coming from the client is as: client:1723 to server:80 But the answer of ISA is server:1025 to client:1723 This answering packet is then blocked by the built-in firewall. Any idea ? Any feedback about the Feature Pack ? Cordialement / Regards Philippe WEHOWSKI
