What ports do I need to open to allow SSL thue sonicwall?

[richardv]

I finally managed to get Exchange 5.5 OWA on Win2K Server running IIS 5 [not an Exchange server]. In house,

https://server_name/exchange/logon.asp

works as expected. From home, I tried

https://public_ip/exchange/logon.asp.

Won't work. Port 443 and 80 are open on the DSL modem/router. Sonicwall forwards ports 443 and 80 to that new IIS server.

However, I did not yet remove the OWA on the Exchange server.

http://public_ip/exchange/logon.asp

takes me straight to the "not SSL" Exchange server and works fine.

I don't know what I am missing.
