The Ethernet port that came attached to my computer’s motherboard was periodically losing its connection with my router so in an attempt to resolve the problem I ended up ordering and installing a redundant networking card. The card seems to be working just fine, the indicator light is a solid green, I can connect and use the internet with other applications with no issues I can connect when I open it over LAN, but for some reason external connections to the server only work on my first port. I should have everything configured right, I disabled my firewall and it still doesn’t work, but if I just move the Ethernet cable to the other port it works just fine. Does anyone have any ideas about what I could look into?
EDIT: Almost immediately after I made this post I realized I forgot to reconfigure the port forwarding on my router to use the IP address from the new card. Problem solved. I feel kinda dumb.
