@empbilly said in Compatibility between VRRP and CARP:
The vlans I have are in a lagg with 4 physical interfaces.
Would this be a problem?
No. In former pfSense versions the network ports for a (virtual) network interface have to be the same same on both nodes. E.g. the port for VLAN 305 has to be lagg0.305 on both.
Configuring a lagg was a way to achieve this if the hardware was different.
But as far as I know, this is not necessary anymore since FreeBSD 12. However, I configured it only this way.
Do I need to have one network (10.10.10.0/24) or can it be one IP only (10.10.10.1) for each VIP in the vlans?
You have to configure each IP and as well the VIP with the correct mask.
I have the vlan ADM_LAN with the network 10.60.0.0/23 and GW 10.60.0.1
On pfsense backup can I put the GW 10.60.0.2?
If you have 10.60.0.1 already configured as gateway on all your internal machines it might be easier to turn this into the CARP VIP and change the interface IP on the primary to anything other, maybe 10.60.0.2 and use 10.60.0.3 for the secondary.
Another point is that we have an AD in our infrastructure, and the AD IP is the DNS in some vlans. How does this work with VIP?
This has nothing to do with HA. It should work like before.
Maybe I'm getting you wrong?
