Lynwood,
This has been discussed innumerable times here on this list, where myself
and other BGP subnet operators have weighed in.
1. Some IPIP users route 44/8 through amprgw. Now that amprgw can reach
us, this fixes their connectivity issues.
2. IPIP users who route properly by NATing out 44-net subnets that they
don't have an IPIP tunnel for will reach us fine, and could reach us
before.
This is not a matter of what the source IP is. This is a matter of amprgw
could not reach non-IPIP subnets prior to now. Now it can, and traffic
flowing through it can as well.
If an IPIP operator wants to *not* NAT out 44-net subnets that are *not*
in the IPIP mesh and not have a default 44/8 route through amprgw, then
they have no route, and can't reach us anyway.

Nigel,
It does?
We considered a lot of these issues before (mainly when developing the
first version of the boot script). Brian is able to ping because, as I
recall, his actual Public IP address is 44...those who IPIP, our IPs are
not.
- IPIP subnets would be required to configure masquerading, making our
Public IPs the one that actually reaching his device, or to require no
further configuration;
- have traffic for BGPed subnets sent through the Main AMPRGW at
44.0.0.1 (on our table 44).
Also, the Security Update and Notes section of the startampr wiki covers
issues for IPENCAP operators with:
-reaching BGP subnets; and
- 44 subnets behind a tunnel with a 44 IP.
(read the last point in the NOTES section - Rob is the one who
discovered it years ago, if you read his email earlier regarding more
specific routes)

This is incredible news! WOOOOOOOOOO!
Thank you much for the work in that regard. This simplifies so much of
the
interconnectivity between BGP routed subnets, and IPIP users.
