Router issue after ISP outage

We had an ISP outage this morning and now the router is not receiving packets from my ISP. It’s been months since I made any configuration changes on the router.

I have a static IP address assignment. I can see the router send ARP requests for my ISP gateway address and a response from the ISP, but other traffic doesn’t work.

If I bypass the router and plug a laptop into the ISP connection and set the same static IP address, the laptop is able to connect.

I tried changing the MAC address on the router’s interface, but that didn’t work.

The router is a RB3011 running RouterOS 6.49.2

Before I factory reset the router, any suggestions would be appreciated!

Thanks!

Oh, I have rebooted the router several times as well as the ISP’s ONT.

It appears to have been an ISP issue. It just came back up. No explanation though.

If you marked as solved can you tell what was cause?
