Pfsense and two networks

lanpfsensewan

I am playing around with pfsense and have an issue with it connecting properly to the internet.

It has the 1 WAN port by default but I also want to run 2 other networks 192.168.3.0 and 192.168.4.0 on 2 seperate network nics. (server has 3 total).

Does my default WAN port need to connect to a WAN port? I assume routers in order to connect to each other requires a WAN to WAN connection?

What I was to achieve is this:

What I want to do is have all 3 networks connected to each other.

No, you don’t need to. WAN, in this sense, is just blocking inbound requests by default. I’ll assume the reason you’re using pfSense is to perform routing functions between those 2 networks (?). If you aren’t using it for any real firewall functions, then you would be alright to, technically, just use multiple LAN interfaces.

I’m not entirely sure what you mean. If you are talking about needing to connect pfSense to your ISP connection, then no.

Remember one persons WAN is anthers LAN. In this sense, your Cisco Firewall’s WAN is the ISP, and it’s LAN is everything behind it. Your pfSense’s WAN is the Cisco Firewall, and it’s LAN is all networks residing behind it.
