I take it HECnet peers are lacking in the U.S.?
I can provide tunnel endpoints. Real Cisco hardware here, real static

If you're doing virtual cisco, do you speak IPv6? If you do I can you a
semi-stable link. My IP is dynamic but my scripts should restore
connectivity within 65 seconds. The longest wait would be for Brian H.'s
scripts.

Look for packets from the neighbor routers you re expecting to see. And
look at the hello packets from both sides and match them against what the
DECnet routing spec says should happen.
If necessary, post a few lines from the result and we can look it over.
