Hello,
I have a website running on 8443 and have trouble accessing externally. For our purposes we will call it
https://1.2.3.50:8443
The internal URL is
https://172.16.0.140:8443
Internal access to 8443 works.
External access to 80 (
http://1.2.3.50) works.
External access to 3389 (remote desktop 1.2.3.50) works.
Externally the connection is quickly reset. When attempting to access a port not allowed on ACL (attempting to hit
https://1.2.3.50) , it is properly logged as follows:
May 13 11:55:14: %SEC-6-IPACCESSLOGP: list INTERNET denied tcp MY_PUBLIC_IP(51232) -> 1.2.3.50(443), 1 packet
This will be repeated for a matter of minutes until my browser stops trying the connection. When attempting 8443, it is immediately a "cannot display webpage" with no persisting load bar.
Here is my full router configuration:

Thanks for taking the time to look at my problem.
