          Would the following work.

          I assign an IP on my WAN for example 77.86.33.156….

          And my Gateway set that to... the actual IP that I get from DHCP from my ISP ?

          Would/Should that work  ?

            Ah, I just re-read the thread and now it makes more sense. I had assumed that because the gateway being given to you is 10.X.X.X then the IP would similarly be 10.x.x.x. But no.

            Ok well the gateway address you are being sent, 10.55.200.44, is outside the subnet of your WAN address which is a real public IP. The subnet mask you're being sent is a /8 which is really weird. Like you say Kcom are not a 'normal' ISP!  ::)

            The workaround should still apply here but the details you have are very odd. If you connect the router in the normal way, without pfSense, does it too receive these same (or similar) details?

            Anyway the workaround for this is to add a route to the gateway address. See:
            https://redmine.pfsense.org/issues/972
            Specifically at the console enter these two commands:

            
# route add -net 10.55.200.44/32 -iface rl0
# route add default 10.55.200.44

            If that works then you can add the commands to Shellcmd so they run at each boot.

            We might need some input from a higher source on this though because it looks….wrong!  ???

              Thanks yes it is an odd setup and yes even usjng the thomson on its own I get alk of the same IP settingd same subnet n everything.

              Ok thanks for those commands ill try them when I get chance to get back on my machine.

              what exactly will those commands do ???

                This is a very old post but may still be relevant:
                http://karooforums.net/index.php/topic,483.msg4677.html
                I expect to see something similar to that posters gateway settings. The issue you may have is the gateway address you're given changes if you reconnect the modem for whatever reason.

                Are you active on the Karoo forum? Maybe time to join if not. There's sure to be some people trying to do something similar there.

                Those commands add a route to the gateway IP via your WAN interface, because otherwise pfSense has no idea how to reach it, and then sets the gateway IP as the default route for all traffic.

                  Ok when I do dhcp on the WAN that 10. Adress does appear in gateways… is that not the same thing ?? Its gets this from dhcp.

                    The same thing as what? What the commands do? Yes except that it cannot be set as default route because without those commands pfSense cannot get to the gateway address, it's outside the subnet of the WAN.

                            Ok.  :)

                            Those routes will only stay in place until your re-boot the pfSense box so to make them run each time the box is booted install the shellcmd package and them add them to it.

                            The other thing is that this depends entirely on Karoo always giving you the same IP details, or at least the same gateway. They may or may not do that. Their setup seems so odd it's impossible to even speculate! If they don't then what is needed is a script to enter the routes based on whatever gateway is given. There were several comment to that effect in the bug report but nothing I've actually seen.

                            It would be great to get a second oppinion on just what's going on here. Anyone?

                            Also I would definitely suggest a post on the Karoo forum. You fellow subscribers will have faced this before any will probably have more info.

                              Hi, Ive added package ShellCMd and have added those commands - and it works!!

                              I do have one little problem though and if I could solve it everything would be perfect!!

                              For some reason I'm getting dropouts when browsing the internet….  under Interfaces - I have errors 0/12.

                              Any Ideas ?

                                Which interface is that?
                                If it's the wifi interface then it's to be expected. For example my own home ath interface:

                                
Status 	up

IPv6 Link Local 	fe80::211:f5**:****:****%ath0_wlan0  
Media 	autoselect mode 11g <hostap>Channel 	8

                                What do you mean by drop outs?

                                  No, errors are on the WAN interface… by drop outs I mean that at certain times the is no response from the internet or takes an age to load a web page. Ive changed to static NAT instead of Automatic and seems to be a bit better.

                                  Thanks

                                    Nothing in the logs when that happens?

                                    Chaning the NAT to static shouldn't make any difference. It only takes any action when you add or remove interfaces anyway.

                                    Something occurs to me. The fact that you have such an enormous subnet on the WAN could be causing a problem here. If you're trying to access some resource that happens to be at address 77.x.x.x then pfSense will try to access it directly without going via the gateway. It may be waiting for something to timeout before then sending traffic via the gateway.
                                    Normally you could avoid that happening by specifying the gateway in the firewall rules on your LAN interfaces and disabling the 'negate rules' in System: Advanced: Firewall and NAT: However with your default gateway setup I'm not sure what would happen.  :-\

                                    See if you can spot a link between the delay and what site you're trying to access.

                                      Hi Stevenw10

                                      Nothing in the logs as far as I can see, I've left NAT on Manaul and I've also noticed that the 'dropout' was pages hanging on "Resolving host" so I suspect a DNS issue, As a test I've pointed one of my hosts to '192.168.1.254' which is the Thomson and also '8.8.8.8' As A Secondary, and so far I've seem to have no drop outs. Presently my clients were using the LAN address of PFSense for DNS.

                                      I've not been on that machine today but will be later on so will let you know my findings…..

                                      IF it is DNS, I wonder what can be done to fix it, dynamically I get DNS servers from my ISP ?

                                      Thanks - All of your help is GREATLY appreciated

                                      Chris.

                                        You can add DNS servers to pfSense that it then uses for the DNS forwarder. Go to System: General Setup: in the webgui. By default the 'Allow DNS server list to be overridden by DHCP' box is checked but you can uncheck that and enter any public DNS servers if Karoo's are a bit flaky. I use 8.8.8.8 and 8.8.4.4, Google already knows everything about me anyway!  ::)

                                            Looks like it was a DNS issue, I've set 8.8.8.8 in general setup and set KC's gateway as the gateway for that DNS server and so far all is well!!

                                            No dropouts!!

                                            :)
