multi wan with 1 LAN port

[mindaugezas]

Hello, so there's my situation , I have a pfsense box with 2 ports.

Port1 - WAN
Port2 - LAN

Port2 is connected to a switch.
There are also 2 other routers connected to the switch (let's call them routerB and routerC).

Pfsense Lan port has an IP of 192.168.1.250. That's what I am using as the gateway in my machine to connect to the internet.

RouterB has an IP of - 192.168.2.1
RouterC has an IP of - 192.168.3.1
I can use these IPs as default gateways to connect to the internet from my main machine as well.

So here's the question -
Is there any way to configure pfsense to use RouterB/routerC to access the internet.

So I could be using different internet connections from different machines over pfsense.

Thank you.
