Today, in HA mode, if the master and slave do not see each other, the Master becomes slave and the Slave becomes master.
It would be nice to have the possibility to have tracking option on WAN interface to determine if the master and slave should swap or not.
For exemple :
- WAN1 has a normal Internet connection;
- WAN2 is connected to lease line to a remote;
- WAN3 is on MPLS line (connection to e remote site).
WAN1 is used for internet connection and as backup line (SPEED FUSION) for remote site connection.
If WAN1 fails, we still have connection to the remote site, but no more access to internet.
Balance should be able to swap Mastership in this case.
