I have a SBS2003. We use OWA with a SSL certificate. I forward port 443 on my ISP modem and it works fine.
Today I implemented a NetGear ProSecure firewall. Now I use my ISP modem in bridged mode. On the firewall I forwarded port 443 to the SBS server. When I try to connect to OWA from home, I get a certificate error. It looks like there is no certificate anymore. I see the certificate error website where I can click, continue to this website anyway. After that the website is not found.
Do I have to open additional ports on the firewall? I had to change the public IP address and reconfigured the DNS settings at the domain host. Could that have something to do with it?
