There is RB750GL, mikrotik 6.10. Before to this firmware was 5.7 with the same problem.
Ipsec tunnel created to the Amazon EC2.
Several times a day the connection is dropped, only helps clean Installed SAs
Can somehow fix it or it's a feature on the ipsec mikrotik?
One could make a script that when connection is broken cleaned certificates, but the machines are turned off on Amazon and nothing to check ping.
