I've got a customer who has a phone system which uses WAN2 and only
works on this port. So I set a rule manually selecting WAN2. In case of
a failure it switches to WAN1, on which the system doesn't work and it
doesn't automatically switch back, even...
so now I made an address group with an exception for the phone system
and set the "all" SD-WAN rule to that group as source. now the phone
system isn't in any other roule as source than the one with the manual
WAN port. Is that the way it should work...
