Well we have an http and an https reverse proxy configured on our F400 firewall. HTTP works fine but the https is causing us some issues. I've uploaded the SSL certificates to the reverse proxy (the complete chain I think) and the key as well. now we can hit it externally and its opening the pages on the right web server with what appears to be a SSL green padlock. however looking in chrome and at the details its saying its using an obsolete key exchange. Safari refuses to connect saying it cannot establish a secure connection to the server. Internally it works on all devices and browsers so its the https reverse proxy that's causing the issue here.
To top it all off trying to use sage pay for payments and it just completely fails and crashing the reverse proxy so no external access is possible until make a configuration change (any change in the reverse proxy just add or remove an IP etc) to being it back to life and allow external access in again.
I've had Digicert looking at it and say they can see nothing wrong with the SSL cert and site setup but as of yet still waiting for Barracuda to actually get back to me with anything useful. Anybody come across SSL issues using the reverse proxy service in the NG firewall?
