Triple WAN Load balancing from the same ISP



  • I have three modems from the same ISP. The first modem is connected directly to pfsense and is named WAN1. The second and third one are connected to routers (each has one) and their respective router is connected to the pfsense interface named WAN2 and WAN3, respectively.

    My ISP has three DNS servers. Do I need to input those three in the DNS server fields of pfsense? Do I still need to setup static DNS routes?



  • That would most likely be a good choice, no need for static routes, the system will do that for you.

    Check with traceroute if you can find another closer upstream address that responds to icmp
