Description
Two nodes with CARP outside and CARP inside.
Outbound SNAT is done via the outside virtual IP.
Changing the vhid of the outside virtual IP breaks the NAT - inside network loses Internet connectivity.
Workaround is to go at Status > CARP (failover) on master node and Disable Carp to force failover to the slave node and then Enable Carp.

not true except where it causes problems with an upstream ARP cache, which we can't do anything about. Disable/enable can update the upstream ARP cache but way too intrusive to just do in every circumstance.
