Ipsec configuration lost

RouterOS General
1

Hi all,

I have 2 RB951Ui-2HnD (6.29.1) routerboards in branch offices connected through ipsec vpn tunnel with RB2011 on main site. both of them has same ipsec configurations except subnets of course. On one branch everything is working perfectly for about six months. But other site every few days losing vpn connectivity, but internet connection is active and there is no other problems. When i connect through winbox i noticed that there is no ipsec configuration at all, like everything is being erased, (policies, peers, etc.). When i reboot router everything returns to normal for few days. Both sites dont generate any heavy traffic only syncronsation of billing application with central server. Only other thing that i noticed during that situation that RB CPU is on 100% and i dont have any idea what is generating that load and mentined problem.

For any idea how to solve problem i will be thankful

BR,
Goran

I’ve just ran into this same issue - IPSec tunnels were working fine for a few weeks. This morning everything was disconnected and WinBox shows a blank IPSec config. Very frustrating.

I’m running a RB2011 and OS 6.29.1

The router seems to sort of freeze up when trying to show any of the IPSec configuration on the command line.
