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?
Re: OWA certificate error after firewall implementation
You will have to look through the firewall configuration to see whether it is using port 443 for anything, such as remote management and change it. If you cannot find anything then call Netgear support.
