1 wan, 3 lans; 3 lan subnet on one interface howto
I have a big question. How can I realize the following system with pfsense, without a vlan switch?
I have a single uplink with fixed ip. I wanna make 3 lan networks on one interface (In the cmts I have only 1 network socket)
(The cmts is only a bridge, not a router):
My pfsense box is x.y.25.2/24 (wan) and 10.0.0.1 (lan)
1. 10.0.1.0/24 for my cable modems and my cmts [gw must be my pfsense]
2. 10.0.0.0/24 for my subscribers (these addresses are assigned to the computers) - that's OK, it's the basic config!
3. x.y.25.0/24 public ip address range for my subscribers, who have special requests. [gw must be my pfsense box]
Thank you for your help.
Multiple IP subnets on the same broadcast domain is a bad idea and not supported. You need a physical interface or VLAN interface for each subnet.
lol, buy a VLAn switch. They're not too much, and you'd only need to cover 4 ports. 3 ports are dedicated to their appropriate VLANs, and then the last is tagged with each, and connected to your pfSense box. It's a better setup.
Definitely separate the subnets - linksys have just launched a new cheap switch with VLAN capability (slm2005 / slm2008) cheapest I've so far seen
Wow, that is cheap. VLAN capability seems to be what separates the boys from the men, so to speak. The prices tend to jump like crazy.
I actually recommened pfSense in a VM on a Dell desktop for someone recently, and it this option was cheaper than a decent router with VLAN abilities. (And I've convinced it will be more flexible, also) Go pfSense!
