Outbound rule Priority vs Outbound Policy Failthrough

#1

Reading about the V8 features. I see the description of Outbound Policy Failthrough. Sounds like the same as an outbound rule using Priority method. What’s the difference and use case?

#2

Its different.
It lets you do something like this:

  1. Send all my traffic from my PC via WAN1 (which is dedicated to me).
  2. If WAN 1 is not available then send my traffic via WAN2 (which is normally used by my business partner).
  3. If neither WAN 1 or WAN2 are available load balance my traffic across WAN 3,4 +5 (WANs used by the rest of the staff).

1 and 2 above can be done with a priority rule no problem - but the priority rule can’t become a weighted balance rule when WAN1 + WAN2 are not available.

By using Outbound policy Failthrough, traffic types / traffic from and to specific places, can use a combination of load balancing technologies based on WAN availability.
