I can only connect to my Apache server using devices on the local network and not from the outside.
I think that this is a port forwarding issue, as I'm getting a Connection Timed Out for the port 8080 (I changed the default port in ports.conf) via canyouseeme.org.
I believe that I modified my port forwarding rules correctly by having the correct IP address and 8080 as both the external and internal start port so I don't think that this is the cause of the issue. Additionally, I checked that my Apache server was listening on port 8080 via the netstat command and disabled the firewall with "sudo ufw disable".
Currently, the only workaround is to set up a default DMZ server with the same IP as my apache server, but I don't want to rely on this. Any tips? Perhaps this may have to do with the NAT configurations on my Netgear Nighthawk R7000P router?
