Problem with WAN/GATEWAY and DHCP

[Falassion]

Hi all,

i have a problem with my pfsense. Sometimes WAN goes down (i think for high packet loss) and it is not able to get back online on her own. I need to disable and reup interface.

I paste DCHP and GENERAL log file.

I set up (router with static IP for pfsense and pfsense in interface with DHCP) The same problem if i set up a static ip for both router and pfsense.

Can you help me set up pfsense to come back online on its own?

I try to disable monitoring for gateway. It remains up but doesn’t work. I lost my connection anyway. I need to put down and re-up the wan interface.

Anyone can help me?

@falassion
Re-enable the gateway monitoring and set an external IP for monitoring in case you've changed that in the meantime.

Then try enabling System > Advanced > Miscellaneous > State Killing on Gateway Failure.
