Last year I followed this instructions

http://www.qsl.net/kb9mwr/wapr/tcpip/ampr-ripd.html

and was able to get a Amprnet Gateway working on a Raspberry Pi 2 with a second USB Ethernet and VPN working OK.

Few months later, I have problem connecting with VPN. i found out later, I have 2 IPs one static and one dynamic on the RPI. This was due to the new dhcpcd.conf implementation. No longer you declare the static IP in interfaces and some say to add it at the end of dhcpcd.conf. I disable dhcpcd at boot and now 1 static IP and no trouble with VPN.

Now, I have problem not receiving the ampr-ripd encap route broadcast.

ip route show table 44 only shows:

default via 169.228.66.251 dev tunl0 onlink 44.163.22.0/24 dev eth1 scope link 44.163.22.128/25 dev tun0 scope link

tcpdump -i etho proto 4 monitor for a long time a no broadcast

I use this tool to ping 44.163.22.1 http://yo2tm.ampr.org/nettools.php

100% packet lost

But with tcpdump -i eth0 proto 4 it shows the ping arriving but my gateway with no route then no answer:

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 00:33:08.740142 IP mail.yo2loj.ro > 192.168.1.112: IP yo2tm.ampr.org > onx.hp2at.ampr.org: ICMP echo request, id 44708, seq 1, length 64 (ipip-proto-4)

How can I diagnose why my ampr-ripd is not receiving the broadcast? Any tools?
