SSTP is unreliable (version 5.0 beta 2)
Setup : two Mikrotik RB750G box through Internet.
We have session drop, and double sessions, very often (3 or 4 times by 10 minutes)
Then we switched to L2TP and all was ok.
can’t reproduce, i’m running RouterOS->RouterOS SSTP connection with lots of traffic, lots of PPS, whatnot, connection is rock solid.
If you get disconnects, enable SSTP debug topics in your log, and check what the log says. Also send supout.rif file to support.
