Hello, I have a redundant router/firewall with CARP and PF/PFSync with the following configuration (simplified for example):
on FW1 (MASTER): ifconfig_em3="inet 1.2.208.89 netmask 255.255.255.224 -tso" ifconfig_em3_alias0="vhid 53 advskew 0 pass xx alias 1.2.208.90/32" on FW2 (BACKUP): ifconfig_em3="inet 1.2.208.91 netmask 255.255.255.224 -tso" ifconfig_em3_alias0="vhid 53 advskew 100 pass xx alias 1.2.208.90/32" on both machines I have something like this in my /etc/pf.conf: net_local="10.209.1.0/24" net_prod="192.168.10.0/24" if_wan="em3" CARPvhid53="1.2.208.90" nat on $if_wan from { $net_local, $net_prod } to any -> $CARPvhid53 it works great but I have a couple of questions: - is it possible to use differents subnets for the "real" ips and the CARP vip ? in other words: I only have three public IPs and I'd like to reuse two of them. I wondered of something like this would work: on FW1 (MASTER): ifconfig_em3="inet 192.168.88.1 netmask 255.255.255.0 -tso" ifconfig_em3_alias0="vhid 53 advskew 0 pass xx alias 1.2.208.90/32" on FW2 (BACKUP): ifconfig_em3="inet 192.168.88.2 netmask 255.255.255.0 -tso" ifconfig_em3_alias0="vhid 53 advskew 100 pass xx alias 1.2.208.90/32" (assuming that the switch is configured properly) - as the state table is synced between FW1 and FW2, is it possible to do some load-balancing on the outgoing address? Thanks!
