[44net] Thank you AMPR and Chris

Hi list, I hope I am not spamming this list; I would like to express my sinciere gratitude to AMPR (everyone who made and makes 44/8 for hams possible) and especially to Chris who helped me a lot in the process for a BGP routable network. Thank you for gifting me an enormous time sink. It was always a dream of mine to connect directly to the "core" of the internet, play around with BGP and, in some ways, completely independent of an ISP. I had given up this dream long time ago until recently my friend told me about AMPR. It's a privilege that hams are given the opportunity to experiment with something that would otherwise be out of reach for hobbyists, similar as radio would be without ham. (while the same with IPv6 is 'somewhat' still accessible, /24 prefixes meanwhile go for 15k and since this is the smallest for anything interesting [BGP, AS], it's just out of reach for experimentation) There are so many exciting things to play with. Subnetting the /24, using /30 or /31 networks for example is something I knew in theory but never really applied in that intensity because with RFC1918, there is no need. BGP I knew in theory but setting up bird and seeing how a session is established, a prefix is announced and watching via looking glass how it propagates through the global interconnected network brings this to a whole new level. I am currently trying to implement a "real" multi homing setup. I have two cheap consumer grade internet links: DSL and 5G. The latter one is CGNAT. Normally there is no way to make anything useful out of this (other than having a manual backup connection). For the first line, I created an ipip tunnel, for the second one a wireguard (due to CGNAT) and connect a third network over them. This network is now accessible straight from the internet on two lines. Exactly as the internet was originally conceived, the packets can now flow on either connection! In next steps I would like to set up OSPF (or maybe iBGP?) and possibly adding more tunnels to create realistic routing networks. And further down, I'd like to see if I can find something interesting to implement anycast. Maybe some spectrum sensing via RTL2832 at two different locations accessible via the same address? Let me know if you have any good ideas. Nick, KM6RDV
