This gets more confusing every day... :) If I have a Web Publishing rule that allows SSL requests to be forwarded to web server... do I ALSO have to have an IP filter that allows HTTPS traffic (port 443)? DO YOU ALWAYS NEED AN ALLOWING "IP PACKET FILTER" IN ADDITION TO ANY "PUBLISHIONG RULE" YOU SET UP??? (OWA suddenly stopped working and the only way to get to it from the Internet is by adding an IP Packet filter allowing "HTTPS Server"!) Alfonso
