Hi All,
As of now, we have a single DMZ controller and guest traffic are going from local to DMZ through GRE tunnel.
Now we are adding a secondary DMZ controller to the setup for redundancy purpose. I already built a VRRP between them for config sync purpose.
So to achieve GRE tunnel redundancy, can I use DMZ controller VRRP IP as a GRE tunnel destination from Local controller?
If yes, what would be the GRE tunnel source IP address in DMZ controllers?
