Hello everybody! I have got a site to site tunnel only for learning purpose. Mikrotik have dynamic public IP, Debian have fix.
There are four private networks behind Mikrotik, but when the IP change one of the SA Src Address is stuck at the previous one in the particular Policy, and the problem is always with the same private network. I have got a same tunnel with an Ubuntu 16.04 server, that works fine, configuration is the same. So if i disable the Peer configuration and enable again after IP change, everything works fine.
Mikrotik RouterOS: 6.46.1
Strongswan 5.5.1
Mikrotik configuration:
