Since before the days of the commercial internet, amateur radio operators have had their own Class A block of IPv4 addresses<\/a>. Net 44 or AMPRNet<\/a> is a non-routeable amateur radio experimentation network and access is only available to licensed radio amateurs around the world.<\/p>\n\n\n\n

While hams have been experimenting with Net 44 since the early days of packet radio<\/a>, interconnecting RF and wired networks via AX.25<\/a>, I’m a relative newcomer. A couple members of the 020 Team are up and running on the AMPRNet and looking at potential use cases.<\/p>\n\n\n\n

My driving use case is the to get around the limitation of one ircddbgateway <\/a>behind a single network address translation<\/a> (NAT). This limitation prevented me from running an ircddbgateway to service my Pi-Star<\/a> hotspots and to use Icom Terminal Mode on my IC-9700 at the same time. What is the limitation? UDP port 40000, used by the ircddb protocol, must be forwarded to the destination system. As the Highlander<\/a> said, “There can be only one.”<\/p>\n\n\n\n

By establishing a Net 44 subnet behind my firewall and assigning a Net 44 address to the Icom, I get around the single IP NAT limitation. There’s a bit more to this, but a Net 44 gateway can be run on a spare Raspberry Pi or your internet gateway router (or any Linux based host). This article is not, however, meant to be an implementation guide but more of a starting point for thought.<\/p>\n\n\n\n

It is also an announcement that XLX020<\/a> is now available on the AMPRNet for use by those with Icom Terminal Mode radios. Our gateway address on the AMPRNet is 44.64.12.57 and you can connect to any module using a To Call of \/XLX020m (replace m with your module of choice). If you’re on Net 44, feel free to connect.<\/p>\n\n\n\n
