      Good evening!
      I'm new to pfsense, mine is the following, I need to do this structure below:

      I have two dedicated links that access another company, they gave me these two dedicated links, I know it's strange but the two links are from the same network, my mission is to connect my lan on these two links failover, I could not do it on Pfsense gives the error:

      IPv4 address 192.168.10.230/22 is being used by or overlaps with: OPT1 (192.168.10.221/22)

      But in cisco it works, I'm going to change from Cisco to Pfsense in cisco the config are:

      Building configuration…

      Current configuration : 3837 bytes

      scheduler allocate 20000 1000
      end

      1-) What should I use to make both Gateways work
      2-) I need them to fail over
      3-) I'm going to make a static route on my LAN to go through one of the two failover gateways
