Tunnel IPIP between RouterOs and Linux

This is a small tutorial on how to establish an IPIP tunnel between a Linux Debian server and a Mikrotik RouterOs.

Linux Machine:

ip tunnel add tun0 mode ipip remote <remote_ip_address> local <local_ip_address>
ip link set tun0 up
ip addr add 192.168.200.1/24 dev tun0

Mikrotik RouterBoard:

/interface ipip add local-address=<local_address> remote-address=<remote_address>
/ip address add address=192.168.200.2/24 interface=ipip1

Check that there are no rules blocking protocol 4 and 94 input and output.

Try to ping the other end of the tunnel:

# ping 192.168.200.2
PING 192.168.200.2 (192.168.200.2) 56(84) bytes of data.
64 bytes from 192.168.200.2: icmp_req=1 ttl=64 time=84.1 ms

It works!
