Last year I discovered AMPRNet, and how any Licensed Amateur Radio operator can have a set of public IP’s. In my spare time, I have been slowly tinkering with AMPRNet and I have recently had some success with creating a Raspberry Pi AMPRNet Gateway. I will post my configuration / how-to in the Amateur Radio section a bit later on over the Christmas break, but here are the highlights:
- Auto-update AMPRNet portal with local public IP when a change is detected.
- When this happens, the AMPRNet is inaccessible for about an hour while things refresh – thankfully it does not happen often.
- AMPR-RIP4D is used for routing.
- Basic firewall with iptables protects the local AMPRNet network.
- Raspberry pi auto-updates weekly.
While the only AMPRNet node I am running currently, other than the gateway, is a D-STAR QnetGateway Hotspot, I will probably use this network segment for APRS andother Amateur Radio use in the near future. Future improvements to my gateway will be to add OpenVPN to allow remote access to my segment of the AMPRNet and a local DNS Resolver.
I look forward to hearing if this information helps anyone (once I post it), so please get in touch with me if you have questions or if this information has been helpful in any way.
Update: I have posted the documentation of how I built/configured this IPIP Gateway here.
