      I have a Cable Modem with 6 external IP's (1 dynamic on subnet 255.255.248.0 and 5 on 255.255.255.0), I bound the dynamic to my WAN address, and Bound ONE of the static's to OP1. I configured a LAN interface for the Dynamic WAN address and I'm on the internet no problem. I configured OPt2 with another LAN address and then procedeed to setup 1:1. I can not get any traffic to pass to or from op1 to opt2. Any suggestions?

        do you have on your OPT an IP out of your LAN range?
        do you bridge OPT to the LAN?
        if no: it wont work (you cannot have the same subnet twice on different interfaces)
        if yes: do you have firewall rules in place that allow traffic between the two interfaces?

        We do what we must, because we can.

          OPT1 (Connected to Switch on Cable modem)
          IP is 172.16.1.127 (fake IP)
          Subnet is 255.255.255.0
          OPT2 (LAN)
          IP is 10.10.1.1
          Subnet is 255.0.0.0

          do you bridge OPT to the LAN?
          No bridging in effect

          Basically my network looks like this
          NOTE: Pfsense machine has 4 network adapters, WAN, LAN, WAN2, LAN2

          Cablemodem –---- Switch --------WAN|PFSENSE|LAN ------ Internal Switch ---- Internal Private Network HERE
                                    172.16.13.129 (fake)            192.168.1.1                            192.168.1.100 - 192.168.1.200 (DHCP)
                                    255.255.248.0 Subnet            255.255.255.0 Subnet   
          Cablemodem ------ Switch ------- WAN2|PFSENSE|LAN2 --------- Internal Switch ---- External Email Server / Mysql Server
                                    172.16.3.127 (fake)                10.10.1.1                                  10.10.1.100
                                    255.255.255.0                        255.0.0.0

            could you post your firewall rules?
