      @galt007 Unless your company was using same network as you, or overlapping network using 10.a.b.X shouldn't be a problem.

      Unless they are using a /8 or /16 mask odds seem pretty high that they would be using 10.30.50/24 or 10.30.55/24 ?

      If they are using such masks?? My 2nd reason applies to them as well ;)

      the 172.16-31 network is prob less likely to have conflict, its rare you see those.. But I do see 10/8 way more than you should, which should be zero ;) or 192.168/16 again you should never see anyone using up the whole freaking network space for 1 segment... Doing so is reason 2 on my list ;)

        @johnpoz Cant recall exactly what the subnet was.

        I'm going to change my 20.30.x.x to 192.168.x.x after I do a quick check on what the ISP assigns as a default.

        Currently I have 4 subnets

        20.30.50.x
        20.30.55.x
        20.30.60.x
        20.30.65.x

          Are you behind a nat? I get a public IP from my isp.. Do you have a isp device, can you not put it into bridge mode so you get a public IP on pfsense wan?

              @johnpoz My ISP router is in DMZ mode and I get a public IP, but the router still uses 192.168.1.0/24 so I cannot use that network on the inside... {insert bad word here} ATT

                Huh? Are you using it for wireless or something? You could for sure use 192.168.1 on the inside.. As long as you had no need to get to this isp device IP for some gui or something.

                  @johnpoz I do on occasion need to get to the ATT Router, but it does not work if I use 192.168.1.0/24 on the inside because pfSense tries to route that network to the ATT router.
                  I did not try too hard as I am not yet close to using up the other 192.168 networks... but I am working on it. 😆
