[SOLVED] Loss of connectivity after reboot of modem
mg85:
Hi!
I used the search function to find possible related topics, but was not able to find any.
I’m noticing quite a strange behaviour after updating to 22.7. Maybe others can guide me in the right direction of solving this.
Whenever I reboot my cable modem (in bridge mode), the firewall loses connectivity once the modem comes up again.
This wasn’t a problem before, so I am expecting this to possibly be software related. No cables are changed, neither the public WAN IP or the configuration.
The interfaces (WAN) and gateways are showing as ‘online’ and ‘green’.
After rebooting the firewall as well, everything is fine again.
I am looking for pointers on where to start troubleshooting to fix this (our cable modem is quirky every now and then and requires a reboot to be revived :))

I'm wonder if your issue is related to another problem I've seen. When it happens again, go into SYSTEM:GATEWAYS:SINGLE.
Press Edit on your WAN, make NO changes, and then press save.

Thank you for the tip. I’ve just tried that, and this does not work (this fixed an issue I had while running pfSense before though and restoring from scratch using the xml approach).
When pulling the cable from the WAN interface I can replay the situation.
- After reconnecting, the gateway shows as online again.
- Restarting Unbound does not have any positive effect.
- I do reject leases from 192.168.100.1 on the wan interface to prevent the cable modem from temporarily handing out an own dhcp lease.
- I have also disabled gateway monitoring
Here’s the log from System > Log Files > General (if that is of help):

Are you spoofing your MAC address by chance?
mg85:
No. It looks to be happening since the 22.7 update. Will have to test with 22.1 and a backup to confirm.
