Packet Loss across RB493G

We have been seeing a wierd issue with one of our 493G’s. We are seeing packet loss when going across the tik. We dont get packet loss going to it or from it, just going across it. If that makes sense.

I upgrade the firmware this morning to see if there was some fw fix. So we are running 5.12.

What info should i post here to show you the setup?

firewall rules to start

Try a different POE and Jumper cable or both.
