<![CDATA[Carp on wan with two networks /30]]>Hello folks
I'm running pfsense for 10years already with successfull CARP setup on multiple interfaces..
I'm aware that with two interfaces I need a network with minimum /29 subnet mask.

Unfortunatelly I'm going to change operator and the new one does not offer an option for subnet /29 :( I can get only /30
According to my knowledge VIP must be in the same subnet as physical int.
I wonder is there any other possible way to do this setup without additional router before pfsense???

What if I get two set of subnets with /30 ??? any clues?

regards
Michael

since pfSense 2.2 3 IPs in one subnet are no longer necessary:

https://doc.pfsense.org/index.php/High_Availability#Common_Requirements

However, I've never tried and there are some limitations:
