Dual WAN failover tolerances
robinsonjas last edited by
I have Dual WAN configured and it's working well, the issue I run into is that it seems nightly I get a lot of emails about failover. Is there a tolerance that can be set for the "Member Down" trigger? Is that after 1 ping drop ... 5 drops??? Seems If I update the heartbeat IP it will straighten out for a day or two then go back to giving me issues w/ failing back and forth overnight again.
I use Google DNS on one side and have tried Quad 9's, CloudFlare, OpenDNS on the other...
Any suggestions would be greatly appreciated.
Yes you can set the monitoring preferences for each gateway by editing it in System > Routing > Gateways. If you are using packet loss or latency rather than only member down on the group it will trigger the failover.
The default settings for throwing an alarm of 20% packet loss and 500ms latency are usually good though unless you have an unusual WAN like a satellite link.
