[44net] Encap tunnels

Hello, New to the list although I do have some JNOS experiences from 12+ years ago. FIrstly, I seem to have volunteered myself as co-ordinator for amprnets in my part of the UK - 44.131.[56-62] so I'd like to thank my predecessor John G1HTL for his efforts over the past couple of decades. I'm trying to discover what the best practice is for routing 44net traffic based upon what I can see in the encap file. Presumably each one of these is a tunnel, what would be defined in Cisco-speak as "tunnel mode nos" (protocol 94)? I'm experimenting here with the G8PZT Xrouter software which runs under dos and provides ip connectivity to radio links. I have a spare Cisco 1721 that I've connected to Xrouter with a SLIP link to the aux port on the router and once I figure out how to get encap routing up and running I may be able to provide 44net access via a radio port (subject to UK licensing of course ) . I'm interested to know what other folks are using to route 44net over the internet? Regards, Nick.
