3 ISP Setup



  • Hello all,

    Can anyone possibly tell me if the following is possible and whether pfSense supports this sort of setup…

    Scenario 1

    I have three connections which I actively use, all are regular home DSL lines.

    The first two DSL connections, are to be load balanced. On the third DSL connection, I want to only allow traffic to certain IP addresses... if both DSL connections are down, the third DSL connection to be the failover and take on all traffic.

    Scenario 2

    I have three connections which I actively use, all of these are regular home DSL lines.

    The first two DSL connections, are connected to a load balanced router. The load lanced router has an IP of 192.168.1.1 for example... would I be able to assign 192.168.1.2 to pfSense with gateway 192.168.1.1? What about NAT? As I understand it, the load blanced router already does natting, would this cause problems?

    For the third DSL interface, it's the same as scenario 1 - Only allow traffic to certain IP addresses.

    Any guidance/advise much appreciated and many thanks in advance!

    Scenario 1 would work. If all three lines are connected to pfSense, you can make firewall rules to match the traffic you want, and direct them to the appropriate Load Balance Pool, Failover Pool, or directly to a given gateway.

    Scenario 2 could work, but would not be ideal. The LAN side of the load balancer and the WAN side of pfSense can be in the same subnet, yet, but the LAN side could not be unless you bridge it to WAN, which would make some features unusable.
