How is Realtek Reliability These Days?

[Patrick M. Hausen]

There was a community driver for Realtek but that was supported up to 6.5 or 6.7 only.

Also that still does not make the hardware any better

I used to swear by Intel for everything, but I’ve noticed more people having success with Realtek lately. I set up a home server with a Realtek chip a while back, and it’s been pretty solid for everyday use. That said, if you’re planning something remote where access is tricky, I'd probably stick with Intel for peace of mind. If you do decide to go with the Realtek 8111H ports, just check the compatibility with OPNSense and maybe look at user reviews to see how others have fared.
