internet but no internet

[cl1nt]

hello,

Im having an issue with my WAN.
Its a coax to ISP router that is in bridge mode, I then have it connected to my bare metal OPNsense.
Its something fishy about the ARP-table. I can get my internet back if I flush the ARP.
But during this time internet is not working I can ping to google dns etc..
Any one have any idea?

Hi,

you mention that you can ping some hosts in the Internet. What is not working then?

You also mention that during flushing the ARP cache the internet does not work... How long does that actually take? Normally it should be an action of a few milliseconds.

Maybe the issue is that your ISP router somehow glues the MAC address of your router? In that case you could fake the OPNsense's box's MAC address on the WAN port.

Can you actually ping any host on the internet from the firewall?
