It is possible to setup multi WAN in pfsense now. http://doc.pfsense.org/index.php/Mul..._Version_1.2.x

I need a little more help to accomplish this. Because my scenario is little bit more complicated than what is explained.
Complications:
I have 8 ISPs Each with different Dynamic IPs
I have no DMZ
I have to use the fail-over switching only incase any of the internet connection fails

Static routing is needed for all systems i mean that i need to specify which LAN IP(Systems) to use which ISP.

The failover should be done when an ISP fails. Anyother easier or reliable setup may also be submitted.

A firewall is not essential but if available i'd be happy to use, because it eliminates a dedicated hardware firewall in existence now.

I don't need anythig additional to be setup like samba, or.. Just a MULTI-WAN, Failover Load Balancing should do.

Thanks in advance.
