Proxy-arp or carp?



  • Hellow to All, im a little confused about what option should i use, this is what im trying to do

    the pfsense box has 3 interfaces:
    lan: 192.168.10.0/24
    opt1: 192.168.20.0/24
    wan: here is the confusion, i have 8 public ips available from my isp and i want lan network to be outbound natted to public ip 1 and opt1 network to be outbound natted to public2, i know that i need to add one firewall's virtual ip, proxy-arp or carp?
    pro and cons?
