      @JKnott:

      The target IP address is, I think .62.x.x.176 (at the far end of the tunnel), with the Hitron sat on .177.

      What address do they give you for your default route?

      When setting up a laptop plugged into one of the Hitron LAN ports to test connectivity, they suggested an IP address of 62.x.x.178, a netmask of 255.255.255.248 and a Default GW of 62.x.x.177

      If you do an arp -a from the laptop does the mac address of 62.x.x.177 tie in with anything marked on the Hitron ?

        They state that once in modem mode only 1 network port will work at a time.

        I have a Hitron GCN3ACSMR, which is in bridge mode.  I can plug a 2nd device into it and get another IPv4 address, as is the norm with my ISP.  However, this has nothing to do with the issue, that is how the subnet is provided.

          That fits in with them providing a /29 to you.  You can use any address between .178 and .183, which means pfSense only had to filter and not route or use NAT.

            Almost! arp -a lists .177 as having 1c-ab-c0-f1-26-b2, the sticker on the hitron lists the MAC address as 1c-ab-c0-f1-26-b0 (note difference in last segment).

              The Hitron will have two or more network interfaces and the one in the sticker might be the MAC address of the internet facing "WAN" interface.

                The -b0 MAC address seems to be listed as the HFC (Hybrid fibre-coax) MAC address.
