Hello Everyone!

So I just upgraded finally to 2.5gbps fiber (yay) I previously had the old black router (GS1100 I think) with my old gig fiber. Had zero issues. Less than a week into my new equipment whenever I have my VPN connected I'm getting insane amounts of errors in my Firewall log on my router. I've tried setting my firewall to Low, I've disabled DNS rebind protection (was getting an insane amount of those errors from my media server) and still no luck, Majority of the times with my VPN speedtests seem to be locked at ~140mbps - 150mbps getting A LOT of the errors Below:

XXX'd out my IP.

No idea what they mean, but It TANKS my internet speed with VPN. The weird thing is, that once I reboot the router, it will work perfectly fine for a little bit, anywhere from 30 minutes to 3 hours, but in the end it always craps out and tanks my speed. Never had any issues with my old equipment but NEED to get this fixed. Was hoping someone could shed some light or have had the same issue, I need this fixed.

EDIT: with ProtonVPN I'd normally get around 1600mbps - 2000mbps down and around 900mbps - 1300mbps up.

Looking forward to the replies! Thanks!

UPDATE: It won't let me edit the post again, but I've noticed even with my VPN off I'm getting A LOT of those illegal packet errors all over the place throughout local devices and the bridge portion. It doesn't affect my speed with VPN off, but still errors all over.
