URGENT help - HA in SG-2100, with multi wan

Hi,

I need to configure two pfsense SG-2100 in HA and multi WAN

I have a fiber /30 with only one ISP IP + ISP gateway, how should i configure the wan ip on pf1 and pf2 please? and virtual ip? what about NAT?

the second WAN is a dsl , i have /32 public IP, or i can use the private network to assign IPs to pf1, pf and carp?

Lan interface will be the one selected on carp configuration
pfsense 1 : 172.16.1.251
pfsense 2 : 172.16.1.252
CARP: 172.16.1.254

i’m not an expert in pfsense, please give details to get your answers. Your help is much appreciated, thanks in advance.

Proper setup of the HA for WAN requires at least 3 IP’s for each WAN.
