Are you sure? Perhaps you're getting dropped because you're not being NAT'd. db0alg.ampr.org does not reply to me on the Internet, but it replies to my BGP-connected AMPRnet address (not via the IPIP gateway at UCSD). This probably means it's internet connected but only allowing 44/8 sourced traffic.
Probably. It's reachable for me via IPIP.
I think it's local to your site. The AMPRGW encap might be strange, but the routing isn't anything difficult. It really should work. I see 44.0.0.1/32 in the encap. I cannot test it's reachability via IPIP, but this means to me the AMPRGW's filters should not be at play.
I'm also able to reach 44.0.0.1, so I agree, the OP has something local to their endpoint going on.
