E2k3 RPC over HTTPS doesn't connect from behind a firewall

[edvinh]

I've configured an Exchange 2003 single server with RPC HTTPS using a 3rd party Cert from Godaddy. I configured Outlook 2007 to connect via https, but can't seem to get into the server.

If I connect via VPN, all is well and RPCdiag shows that all services are connected via TCP/IP, but when trying to connect remotely without dialing into the VPN, Outlook asks for my passwd and immediately disconnects.

The server is behind a firewall, NAT has been properly configured and ports 80 & 443 have been opened, as well as 6001, 6002 & 6004, yet nothing I do connects me to the Exchange server via https.

Does anyone have any ideas? I've looked everywhere on the net, and really cant find anything.

Thanks in advance
