Noobie Link Monitor and SD-WAN questions
On a client's T35 running 12.5.7 U3, I am setting up SD-WAN for the first time and doing the link monitor setup first. The help article here https://www.watchguard.com/help/docs/help-center/en-US/Content/en-US/Fireware/link monitor/link_monitor_about.html states, "Specify a different Link Monitor host for each external interface."
I want to know if their VoIP phone provider's circuit (Fonality/Netfortris) should work best over Spectrum or over their new AT&T connection, so I want to use their VoIP phone provider's FQDN as the target on both of the interfaces. Will that cause problems? Is that what I should be doing to monitor each provider's quality?
On External-1-Spectrum, I have targets of ####.pbxtra.fonality.com and 188.8.131.52 with pinging to both. On External-2-ATT, I have targets of ####.pbxtra.fonality.com and one of AT&T's DNS servers with pinging to both.
What do you think?
