help routing two networks and two WANs
-
Hello! First post on here! Please bear with me if this is something trivial! I am having trouble deciding how to approach routing two networks with two WANS. Here's my setup:
LAN 1: 172.20.0.0/16, connected to WAN 1 (my location)
LAN 2: 10.0.1.0/24, connected to WAN 2. (other location)LAN 1 and LAN 2 are separated physically, with a wireless link that I've setup between the two locations. At present I am able to load balance the two WANs on LAN 1, as I have a NIC directly connected via the wireless link.
What I'd like to accomplish is having either LAN have WAN failover setup with the other networks WAN. If I had both WANs physically present at my pfsense box I could do this no problem, however WAN 2 is present across the wireless link.
My thoughts are to disable DHCP on the LAN 2 network, and setup a DHCP on pfSense that LAN 2 will utilize as well, however, because I only have one interface on my pfSense that is connected to LAN 2, I'm not sure how to set this up. I'd like pfSense to be a router, and have firewall rules, and be DHCP for both LANs. I'm thinking I may need to have a transparent bridge, and / or VLANs setup I just have no idea how to do this. I'd like to utilize LAN 2 router to get out to the internet, but only for that.. I want pfSense to be the first stop for LAN 2. Hope this make sense. Any thoughts?
Thanks and God Bless!
