I have a ASA 5585 running current code. We have an issue where users inside get a Secure Connection Failed when they try to http or https to a web server on the outside interface. I have firewall rules that allow traffic to the destination IP addresses for web and https. When I try to http or https to the web server from a pc not on the inside interface subnet, not behind the ASA at all, I connect just fine. I think I have a cert issue but don't know where to begin to tshoot this. The host on the inside interface is a linux server running firefox browser, both with up to date versions. Does somebody have a book or config guide about passing SSL through the firewall? We have imported our certs to firefox but the same problem occurs.
