Modem to Router to Pfsense Set Up
-
I have 2 Internet Connection from 1 ISP. I have read somewhere that using 2 internet connection for Multiwan from the same ISP will not work because they might acquire the same Gateway. The question is, How or what configuration should I do to the router to enable it to be plugged in one of my Pfsense ethernet ports and be detected as a gateway?

You could just look and see if your IPs you get from your ISP on the 2 connections are in fact the same network and have the same gateway. If they do not then your golden.
If they do - you could always just nat one or both of them before connecting to pfsense.
-
tried it. they do get the same gateway. Which NAT set up will I do? NAT from the router or from the Pfsense?
-
well you can not do nat at pfsense for your ISP, so at the isp device (router) nat the IP that pfsense gets.
example
isp1 public 1.2.3.50, gateway 1.2.3.1 - router1 10.0.1.1/24 –- 10.0.1.2/24 pfsense wan1
isp2 public 1.2.3.60, gateway 1.2.3.1 - router2 10.0.2.1/24 --- 10.0.2.1/24 pfsense wan2Now pfsense see's 2 different connections with 2 diff networks.

You can leave one router in bridge mode so that one of your pfSense WAN interfaces will have a public IP. Makes it easier for port forwarding, UPNP etc later on.
