WAN link getting down continuously

Hello Everyone!!

I am using a Sophos XG210 firewall and have configured multiple WAN links.

In the WAN link manager one of the ISP gateway which i have setup for fail over, gets down continuously and whenever i update that particular interface manually it gets UP and starts to work normally again. Its very hectic and time consuming to manually update the WAN interface again and again. Guys please suggest me what should i do.

Thanks.

Gobind Jha.

Hi Gobind Jha

Please verify the Interface Negotiation speed with the upstream device, Please add ARP entry in the Sophos XG for the upstream device, Please check the failover condition configured for the specific Interface.

Also check the dgd.log and networkd.log on Shell, to find a root cause.

In case it stop working, can you change the Failover Rule to "google dns Ping".

Will it still fail?

Then in case of a failure, please perform a tcpdump on the interface to see, what is actually going on.
