I have an ASA 5510 running 8.3 code. A 3rd party vendor that manages some servers in our network via a VPN connection is trying to get 2 of these servers setup on WSUS through the VPN tunnel. I've ensured that HTTP and HTTPS as well and SSH services are open on the Firewall page on the Outside Interface.
I seem to be able to telnet to port 80 to the server on the far side of the tunnel without issue but when it comes to 443 traffic it looks like the traffic is somehow being blocked. As you can see in the screen shot below it looks like the Firewall is having an issue with the return traffic - it seems to think that it is being spoofed and is therefore dropping it. Any ideas on how I can correct this?
