I have a RB/1000, ROS4.x running for 2+ years not.
It is working just fine, but suddenly it was not reachable from external network.
The device is located behind a loadbalancer. To reach it it builds a pptp tunnel
to a central server. This worked for a long time. Since a few days it produces
errors in the syslog when trying to bring up the tunnel
hope this contains all information on the error.12月8日13:27:30 i59F7802A pptp,ppp,info miktik: MT-1: initializing...

There were no changes in the configuration, only if someone hacked it.
The pptp server is located on a RB532A/ROS3.3
I assume the problem on the RB1000, the profile is used by ~40 Mikrotiks and this
one is the only with encryption rejected.
Is there a way to open a connection to this board?
It is located about 6 driving hours from my position
I already tried to set up a second profile and tested all possibilities of encrption/compression settings, without success.
Any ideas ?
