I'm trying to forward TCP-8443 to a web server, listening on the standard HTTPS port, inside my home network. The ISP blocks incoming TCP-80 and TCP-443 hence, I'm using that alternative port. Again, I'm new to opnsense but this should be straigh forward; this used to work on my old pfsense setup
I followed this well written and concise tutorial (https://forum.opnsense.org/index.php?topic=8783.0).
I went to Firewall > NAT > Port Forward and set it up. I allowed it to create its own firewall rule in Firewall > Rules > WAN. See the following screen shots.
The browser, when I go to visit the site, says the following which leads me to believe I'm actively getting blocked:
ERR_CONNECTION_REFUSED
Seems correct.
I assume you checked that the traffic arrives at your WAN address?
Do you see any blockings in Firewall > Log Files > Live View?
(Especially with destination being the WAN address (with ':8443', which would mean natting doesn't work properly (had this just yesterday, all of a sudden))
None that I can see but, the filtering on the live view is less than ideal. I'm able to filter by "WAN" and I see everything hitting the WAN. I can also filter by ":443" and see some traffic but it looks like it's all outbound. If I filter by ":8443", I get nothing at all.
