I have an ASA5510 that I am trying to set up for remote access using SSL VPN & clientless SSL VPN. I have followed the config guides on the Cisco website as well as the config guides elsewhere on the internet to no avail. I have a TAC case opened and have spoken with 4 engineers thus far. I have tried several software versions on the device and they all give the same result.
When going to https://(outside interface ip address), I receive the expected ssl certificate error, then I click to continue to the website, and the browser never loads a page. I can see the ssl negotiation in my debug, and it completes that portion. My http debug shows the get requests to https://(outside interface ip address)/+CSCOE+/index.html and/or logon.html, but the page never loads.
Has anyone ever seen this before---any ideas or what would be helpful in troubleshooting this further?
Thank you in advance!
