First please make sure you have IPIP protocol 4 (IPIP) forwarding in
both mikrotik routers:
First router (192.168.70.1):
ip firewall nat add action=dst-nat chain=dstnat in-interface=YourWanIf
protocol=ipencap to-addresses=192.168.70.100
Second router (192.168.70.100):
ip firewall nat add action=dst-nat chain=dstnat in-interface=YourLinkIf
protocol=ipencap to-addresses=192.168.0.10
Also, make sure that on both routers you have enabled forwarding of ipencap:
ip firewall filter add action=accept chain=forward comment="IP Encap"
protocol=ipencap
With these in place, you should see incoming traffic on your ampr0
interface, including RIP routing info.

I'm trying to configure a gateway with Debian and
ampr-ripd never responds. I tried several tutorials and it never works.
My network structure is as follows;
eth0 (192.168.0.10) --> (192.168.0.1) [router(mkrotik)] (192.168.70.100) -->
(192.168.70.1) [router (mikrotik)] --> ISP
(I know, it's a little strange but I need the 2 mikrotiks)
I have configured my external IP (it is in bridge mode) with a dyndns. For this test the
firewall is completely open.
First I create the tunnel:
ip tunnel add ampr0 mode ip local 192.168.0.10 ttl 64
ip link set dev ampr0 up
ip addr add 44.153.x.x/32 dev ampr0
ifconfig ampr0 multicast
Then I add the path:
ip rule add to 44.0.0.0/8 table 44 priority 44
Finally I launch ampr-ripd:
ampr-ripd -a 44.153.0.0/16 -i ampr0 -t 44 -d
This process never receives a response.
Is there some configuration missing or am I misunderstanding the process? Maybe the
mikrotiks are missing some configuration? (are the connections under NAT)?
