If IIS is operating on the ISA, you have a choice between web publishing and packet filters. Some details on your setup would help in providing a specific answer...

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"!)
