Pesky Linux Node Not Receiving Any Inbound Connections, However Sending 12 Outbound.

Have set up plenty of nodes with no issue in the past connecting to the ravennodes network, but it seems that now one of my linux nodes will not receive any inbound connections for whatever reason. I have checked the ufw, the router port settings, etc. Port 8767 is open and good to go, I get 12 outbound connections, but no inbound connections. I am able to ssh to the machine, so I am fairly confident that it is not a port issue. The node is also fully synched, I had just moved places and when I set my node back up, I noticed after about a day that it was not connecting to the ravennodes map, and figured I'd reach out and see who else might have come across this issue. Thanks a ton!
