Ethernet driver crashing?

[KhakiHat]

After setting up a router with OPNsense and then digging deep on how to port-forward successfully(for someone who knows very little about port-forwarding), I seem to have found a new problem.

 

Maybe a problem of my firewall within OPNsense, or within my operating system itself (All of my settings within OPNsense are 99% default, outside of port-forwarding).

A somewhat random occurrence, if I host a Minecraft server from my main rig, port-forwarded through my now OPNsense router build, I have no problems with my gaming PC/hosting machine, the problem arises when I attempt to play Minecraft at the same time as trying to host the server. Almost immediately after logging on, my internet connection drops. Requiring my to do a full restart of my PC before the ethernet driver and can be turned off and turned back on within Device Manager. I attempt to do a regular restart, my PC will crash for whatever reason is likely causing the ethernet problem to begin with. Also if I attempt to disable and re-enable the driver for ethernet, Device Manager will crash.

 

My PC is completely up-to-date from what I can tell, ASUS ez update claims I have no pending updates, as well as Windows not needing any updates.

 

Not sure really where to go from here. My PC rig isn't really lacking anything as far as my hardware, and I have a 1200MB/s internet connection.

 

For reference, I have a ASUS ROG Strix Z690-E GAMING motherboard, 32GB DDR5 CORSAIR Dominator Platinum RGB @ 5600MHz RAM, and an Intel i7-12700k @ 3.6 GHz. Which in my opinion should likely be well over the requirements for hosting and playing a Minecraft at the same time.

 

Any suggestions? Any driver updates I'm unaware of? Ways to search that aren't obvious?

 

I'm all ears.
