      Again, great product!

      Environment 1.0.1-SNAPSHOT-01-19-2007 built on Fri Jan 19 15:38:01 EST 2007
      LAN  192.168.1.1
      WAN DHCP(192.168.0.2)  SS6520 ADSL2+ Router  @192.168.0.254
      OPT1 DHCP(192.168.2.2)  SS6520 ADSL2+ Router @192.168.2.254

      Load Balancer:Pool
      Wan1BalanceWan2  gateway  wan opt1 64.235.192.30 64.230.199.5 Load balance Wan1&Wan2   
      Wan1FailoverWan2  gateway  wan opt1 64.235.192.29 64.230.199.5 Traffic via Wan1 | Wan2

      The Wan1FailoverWan2 Pool is used for outgoing SSH HTTPS.

      Both SS6520s have PPPoE connections with Static IPs except that the Gateway for WAN can change between 64.235.192.29 and 64.235.192.30.

      Changes in the Gateway cause

      The SS6520s are in router mode for 2 reasons
      Supply a PPPoE client and allow wireless internet access bypassing pfsense.

      Any suggestions besides picking a different monitoring IP?

        the standard workaround for dynamic ip addresses is to put in a simple (maybe Linksys) router in front of the pfSense.

        You might do a traceroute and pick the next hop as a gateway.  it might work.

        Dynamic gateways! wow. what will ISPs think of next to hassle us?
