We are running NAT Overload and when I show the NAT translations, that Port is not in the translate table for that traffic. In other words, it almost looks like the router is denying return web traffic, but that port is not seen by the router as "established" traffic. Anyone have any ideas? Thanks.
There is lots of port redirection on this router, but not on the NAT Overload IP address. Unfortunately, I can't post the whole config as there are some serious security issues that need to be addressed. Let me know if there are some specific parts that would be helpful to share.

In Syslog I also se...
