Hi, I’ve set up a routerboard rb951 with a sstp server without certificate, then I opened the 443 port.
On another rb x86, I setup the client but it can’t connect.
Here’s the logs on server.
On my knowledge, if you do not set any cert, SSTP do not work…
BUT
OR you disable on bot devices /ip service www-ssl
OR you change on both device the SSTP port
BECAUSE
it use same port as SSTP service…
The www-ssl is disabled on both devices. I tried now openvpn and it works but only if a create a certificate like this on bottom. Is it correctly created?
If it works, it’s ok 
Yes, but I want a secure VPN so if the certificate creation is a delicate matter I would do it correctly.
I am running several sstp tunnels on ports 444 without certificate just using user/password. Not problem ať all.
usually i use port 7787 by self generated cert…
I want see if you deduct why I use that port number…
Gaming port? Masking tunnels as gaming activity?
not… SSTP = 7787 on telephone… 
Nice, but I have to use the 443 because the client provider do a heavy traffic shaping.
ahh…
If you not using VoIP/SP, port 5060?
There also a VoIP client
For the opened port, to prevent portscan the RB server will accept only the connection from the /16 subnet of the client provider.
For the other vpn I use l2tp/ipsec.
