I am looking for a temporary backup to a Cisco PIX firewall that has 5 IPs all in use. To date the *Nix based firewalls I have seen (Endian, PFSense, m0n0wall) basically are suited for home use, i.e. 1 static IP can be used. Does anyone know of a solution that would allow me to swap between the PIX and a Linux based firewall? Of our 5 IPs at least 2 have to be pointed to individual WAN addresses, hence the need.
