      Thanks for that info.

      You do need to make sure pfSense is not blocking Private Networks, RFC 1918 & 4193 (bottom of the Interfaces settings page) as Cox appears to use some of the private ranges (v4 and v6)  for their internal network.

      That would only matter if you are trying to accept inbound connections from those networks. Nobody should be doing that.

        Cox doesn't seem to work right for me if I check the block 1918 box. This came up several years ago in this topic:

        https://forum.pfsense.org/index.php?topic=66289.msg361564#msg361564

        The Cox Cable tech support folks position is that they are within the RFC 1918 rules with these addresses as they stay on the private Cox Cable system and are not passed to the Internet.

        and a quote from the link to DSL Reports Cox forum, the Cox Tech rep there:

        CoxTech1

        That' correct.  These IP's are being used within the Cox network and not being used for routing across the public Internet.

        I can't break anything until late tonight but if you want me to try some testing tell me what you'd like to see and I'll try doing it then.

          I am merely stating what rules that checkbox puts in place and their effect.

          Unless you are receiving inbound connections into WAN from those addresses they have zero effect, regardless of what an ISP thinks. If they tell you you need to allow that, you should be asking many more questions.

          block anything from private networks on interfaces with the option set

          block in log quick on $WAN from 10.0.0.0/8 to any tracker 12000 label "Block private networks from WAN block 10/8"
          block in log quick on $WAN from 127.0.0.0/8 to any tracker 12000 label "Block private networks from WAN block 127/8"
          block in log quick on $WAN from 172.16.0.0/12 to any tracker 12000 label "Block private networks from WAN block 172.16/12"
          block in log quick on $WAN from 192.168.0.0/16 to any tracker 12000 label "Block private networks from WAN block 192.168/16"
          block in log quick on $WAN from fc00::/7 to any tracker 12000 label "Block ULA networks from WAN block fc00::/7"

            Edited to change Bogons to Private Networks which is what I meant to say.

            Derelict, I just took my network down for a few minutes to play with this again.

            If I have (not Bogons) private networks blocked I can't connect to the Cox DHCP server to get IP addresses for my WAN if I attempt to renew them.

            If I allow (not Bogons) private networks I have no issues getting a response from the Cox DHCP server and both v4 and v6 IP addresses for my WAN.

            Cox does things their way and there is nothing we customers can do to change that so we just have to puzzle out the problems they cause and hopefully solutions. They don't even warn us about the strange stuff, tripping over it is your first indication there is something wrong.

            Other topics discussing this:

            https://www.dslreports.com/forum/r30380140-RFC1918-DHCP-servers-on-COX-network

            Had a fun one today. COX is using 10.0.0.0/8 addresses and 172.16.0.0/12 addresses on their WAN. This causes a headache for the end subscriber if one is blocking RFC1918 addresses on their WAN interface, as it may break DHCP.

            http://www.techexams.net/forums/off-topic/114996-cox-using-rfc1918-addresses-their-wan.html

            When setting up my router a few weeks ago I found I had to unblock 10.36.96.1 on my WAN interface for DHCP client and server.

              I have Cox IPv4 and IPv6 and I have to do no such thing.

              I would be curious to see what was logged in the filter log when it failed.

                With Private Networks blocked I'm seeing the Status_Interfaces browser activity spinner just continue to spin after I press the "Release" button until the page times out.

                No IPs are shown on the pfSense home/status page and both gateways, v4 and v6 offline.

                If I allow the private networks, save and apply, then I'm getting IPs and the gateways come up. See the second set of logs.

                I'm far from an expert at this so I don't have any real idea what is going wrong other than what I found on other topics about it being a DCHP server access issue.

                If I can provide you any information that might help I'll be glad to try, just tell me what you need.

                  Interesting. Public address from a private-addressed server on WAN.

                  You wouldn't happen to have the firewall filter logs from when you have the RFC1918 block enabled would you?

                    In that unique case you can make an RFC1918 alias and:

                    Pass the DHCP traffic in on WAN
                    Block the RFC1918 in on WAN
                    Rest of your WAN rules

                    Disable the checkbox for RFC1918 on WAN.

                    The ISP should not be expecting you to accept that traffic into WAN. I would open a ticket with them.

                      The firewall logs always show as empty with the private block enabled or disabled.

                      I've talked to Cox tech support by phone and via their DSL Reports rep and no information is public about their use of the private network space within the Cox system. Not even a simple list of "we use these ranges, pick something else for your use" which has bitten folks for some time now when they have duplicates.

                      I'll skip trying to create firewall rules, want to keep the pfSense setup as basic as possible.

                        I believe the problem was my rental ASSUS cable-modem/router-wifi. It was not passing the prefix subnet information, only individual ipv6 ip addresses for the one /64 subnet that it was using for direct connections to its LAN side. It was not sharing the rest of the /60 block that was showing up on the WAN side.

                        When I swapped it out for a NETGEAR CM700 and plugged the pfsense firewall into the NETGEAR CM700 ethernet out, the pfsense fw picked up the proper IPv6 information to distribute IPv6 addresses on the LAN side. That's what I wanted. I am going to mark this as resolved.

                          @obitori , I know this is pretty old at this point, But I'm also a Cox customer, battling my way through a similar setup with pfSense and a netgear CM1000 cable modem.. Any chance you could provide some details on your pfSense config to get it to use the ISP provided block of addresses?
                          Thanks for any info you can provide.

                            @martywise Nothing fancy, my WAN page has these set:

                            Use DHCP6 to configure
                            use /56 prefix and send a hint to the ISP
                            reject leases from your modem's internal IP address
                            don't block private networks (once working you can try blocking)

                              @stan-qaz -- Thanks for the info. Going through my settings again I see what I'm missing. I am currently only asking for a /64 and that's what I'm getting... And, it changes each router reboot.

                              With your config, do you get a static block? Have you seen the prefix change over time? If so, how frequently?

                              Thanks again.

                                @martywise No reason to only ask for a /64 but it should work if you have only one internal LAN.

                                Try checking: "Do not allow PD/Address release" to see if it helps stabilize the prefix.

                                You do not get a static block, you get whatever Cox wants to hand out. Some times and some areas you'll be on the same prefix for a long time, other times and areas (like Phoenix last year) you'll get a different prefix every couple months. As long as you avoid hard coding the prefix into some rule or DNS entry you will never notice it changing.

                                  @martywise said in [RESOLVED] Problem with Cox cable-modem and pfSense with IPv6 routing on pfSense LAN side:

                                  And, it changes each router reboot.

                                  Check Do not allow PD/Address release on the WAN page. Also, no harm in requesting more /64s than you need. The IPv6 address space is huge, with gazillions of addresses. I get a /56 from my ISP and currently use 4 /64s.

                                    @stan-qaz Fabulous! Thanks. This is definitely working. Now, I get a LAN IPv6 address and a /56 prefix that does not change each reboot. As you say, it will likely change periodically. I've had Cox for over 20 years. In that time, my IPv4 has changed only infrequently... I expect this will probably be similar.
                                    Thanks again for your help!

                                      @jknott I now have the "Do not allow PD/Address release" option checked and overall, things seem to be working.
                                      As for address space -- that's about what I'm after too... I only want to create a few subnets, with at most a few dozen nodes on each.
                                      Thanks for the assistance.

                                        My IPv4 address is virtually static, but my host name is based on modem and router MAC addresses. If I change hardware, the host name will change. If I change my router or it's NIC, my address will change. On IPv6, my prefix has survived modem and complete replacement of the box I run pfsense on. I suspect it might take a nuke or two, to change it. 😉
