      Our new ISP has issued us a full class C network with an out of the ordinary config.  Network config as followed:
      Usable public IP’s  216.XXX.XXX.1-254
      Subnet 255.255.255.0
      Default GW 65.xxx.xxx.197/30
      I have setup the Wan interface as follows:
      IP 216.xxx.xxx.1
      Subnet 255.255.255.0
      GW 65.xxx.xxx.197
      The LAN interface is working ok I can access the server but that’s a far as I get.  I cannot access the internet.
      I used the wizard to setup pfsense, could someone please advise as to what needs to be done to enable internet access.
      Internet
      |
      |
      WAN (IP 216.xxx.xxx.1 SN 255.255.255.0 GW 65.XXX.XXX.197)
      |
      Pfsense server
      |
      LAN (IP 172.16.0.1 SN 255.255.255.0)
      |
      Local lan
      Thanks in advance

        I would suspect that 216.xxx.xxx.1 should be the gateway on YOUR side.  The gateway address they gave you is for their equipment.  We have a similar setup, and in communicating with our carrier (XO) they intermittently swap the meaning of 'gateway' to mean our gateway (their dual t-1 router on premises) with their gateway (who knows what or where, somewhere upstream).

        Try setting your gateway as 216.xxx.xxx.1/24
        Set your wan IP as whatever you want between 216.xxx.xxx.2-254

          Thanks for the reply mhab12.

          I tried your suggested configuration but it doesn't work.  I tried using 216.xxx.xxx.1 and 216.xxx.xxx.254 as the gateway but no internet connectivity.  I actually configured a Clarkconnect box to test it and it works with the odd gateway.  I have been playing with this for about a week now and it is really getting frustrating.  Thanks again for your suggestion and anymore help you maybe able to provide.

            What WAN IP and subnet mask are you using when Clarkconnect was working?  I assume you entered the gateway as 65.xxx.xxx.197?

              The WAN IP was 216.XXX.XXX.1, subnet 255.255.255.0 and gw 65.XXX.XXX.1, I was surprised it worked like that.  I just got off the phone with XO and they didn't send me all the info with the original config email.  First off I needed to put a router inplace between the XO modem and pfsense with the correct info.  Here is what I needed to do to resolve it:

              Internet
              |
              XO modem
              |
              WAN ( IP 65.XXX.XXX.198 Subnet 255.255.255.252 GW 65.XXX.XXX.197)
              Cisco 2600
              Public LAN (IP 216.XXX.XXX.1)
              |
              WAN (216.XXX.XXX.2 subnet 255.255.255.0 GW 216.XXX.XXX.1)
              pfsense
              LAN (IP 172.16.0.1 Subnet 255.255.255.0)
              |
              Local LAN

              So in actuality your hit the nail on the head with your first reply.  Once XO updated me with the complete info I was good to go.

              Thanks for your assistance.

                Too funny that we both have XO…I'm jealous of your Cisco 2600, a slight improvement over our XO provided Nortel / Tasman 1002 with one dead LAN port (luckily there are two available).

                  Yes it is.  I actually had an extra 2600 router here that I tossed in between the XO Hatteras modem and pfsense.  I was initially trying to connect pfsense directly to the the Hatterras box.  Like I mentioned in my previous post I was surprised CC worked like that.

                  Thanks again for your guidance fellow XO user!!
