Any ideas? I feel like I did configure the tunnel correctly, but I don't see anything on the LAN. Will post config if needed.
Your gateway config looks OK to me. Your route entry appears in our gateway:
44.98.17.32/27 via 73.1.142.180 dev tunl0 proto ampr-ripd metric 4 onlink
(of course useless for us, because the method described on the WiKi does not provide connectivity for gateway stations other than amprgw)
I can ping your external address. Maybe Comcast or the modem is filtering IPIP?
