In general, all encapsulated packets sent to the amprgw router for decapsulation and forwarding should have inner source addresses on the 44.0.0.0/8 network, since they are being originated by hosts on that network.
The owners of the following gateways should contact me or consult the error listing in the /private/pkterrors.txt file regarding misconfiguration of their gateway routing rules which is leading to the sending of packets to amprgw which have a non-44 inner source address. These packets are being discarded by the gateway router, so they're not being delivered anywhere. This could be caused by an erroneous default route pointing at amprgw. Probably you shouldn't have one of those.
This isn't causing any harm, but it's not doing any good either. - Brian
