My WP homepage works, but the other pages don’t when accessing from out side of my network

So, I host my WordPress website on my PC. 192.168.1.5:25566 (port forward). On my LAN, I can access homepage and other pages on the site. But from outside the LAN, I can access homepage but cannot access other pages on the site. I suspect this is due to the links to the other page being 192.168.1.5:25566/page2, as 192.168.1.5:25566 is set in Settings>General.

So, I put my WordPress site address in Settings>General to 80.90.484.594(my public IP, not my real public IP cuz I ain’t giving that out). After I do this, WordPress site and all it’s pages can be accessed from outside the LAN but not inside the LAN. I thought I set my Apache server to listen to 192.168.1.5:25566 but somehow WordPress, which AFAIK runs on Apache, cannot be accessed from my LAN. Is there a way to access all pages from the outside network as well as inside?
