      Please help.
      I want to loadbalance my two adsl account, but the following error occurs whenever i create a new pool in the load balancer.
      Error: "121.97.x.x is currently being referenced by an interface ip address opt1".
      Note: 121.97.x.x is the static ip address of opt1 (adsl account)
      I'm using 1.0 release version of pfsense.
      Thanks in advance.

        your montior ip should be a gateway over your dsl connection
        do a trace route use the second or third hop down usually the one after your dsl modem and the gateway you dsl modem same thing for your second connection

            Thanks for the replies, my load balancing is functional now.  ;D

            I have notice another problem though: when my WAN connection is down even though my OPT1 connection is up, i can't seem to access the internet but in the status page of load balancing OPT1 is online. I have tried it many times, pfsense can't seem to failover to UP connection.

              You lose your dns servers at wan. configure one dns server from each wan and add a static route to the wan2-dns-server/32 through the wan2 interface. This way you won't lose dns when unplugging the main wan.

                I'm sorry if this may sound too much request but how am i gonna do that (making a static route to DNS server via WAN2)?
                I'm still  a newbie, still trying to learn the whole PFsense setup.
                You're firewall rocks! More power!!!

                  Let's assume your DNS-Servers ar 1.1.1.1 and 1.1.1.2 for WAN and 2.2.2.1 and 2.2.2.2 for OPT-WAN.

                  At system>general enter one DNS Server of WAN and one of OPT-WAN like 1.1.1.1 and 2.2.2.1

                  Then at system>static Routes add a route:
                  Interface OPT-WAN
                  Subnet 2.2.2.1/32
                  Gateway OPT-WAN-Gateway (either look this up at status>interfaces or at interfaces>OPT-WAN if it's static).

                  Save and apply.
