    if you want one LAN for one WAN, you could do it with 5 ClearOS. One as a KVM hypervisor running 4 instances of ClearOS. With one ClearOS you won't get separation of your LAN's. Even WAN's won't separate if one fails, but otherwise source-based routing should work.

    I even have more NIC's on my clearos so its not a problem.. was thinking about 4 cables in, and 4 out, then to 48p switch where i could have 4 nets each with own ext ip, and ports sorted like this net1:1-12, net2:13-24, net3:25-36, net4:37-48

    i was thinking also about connecting it all to my server, create 4 vms with clearos on and the route traffic trough them to 4 vlans wich i can use inside the server..

    but its still 4 separate "devices" i was hoping i can connect it all through one clearos :D

    I have no idea about this set up. If you have four ports on the ISP box and they carry different traffic, then you'll need 4 NIC's in ClearOS unless you can redirect all the ISP traffic over VLANS on a single port.

    ClearOS is not really designed to tie a WAN port to a LAN port and port forwarding operates on all WAN ports at the same time.
