I need help with this scenario,One IP can only connect three sstp clients!

Server side: Routeros sstp server (v6.45)
Client: routeros sstp client (v6.45)

The client can only connect three sstp clients,The fourth pptp client can’t connect

The process is as follows:

1:Make a certificate

/certificate add name=MYCA common-name=MYCA days-valid=3650 key-size=2048 key-usage=crl-sign,key-cert-sign

/certificate sign MYCA name=MYCA ca-crl-host=xx.xx.xx.xx

/certificate add name=Server common-name=Server days-valid=3650 key-size=2048 key-usage=digital-signature,key-encipherment,tls-server

/certificate sign Server name=Server ca=MYCA

/certificate set Server trusted=yes

:for myserver from 1 to 10 do={/certificate add name=(“Client” . $myserver) common-name=(“Client” . $myserver) days-valid=3650 key-size=2048 key-usage=tls-client}
:for myserver from 1 to 10 do={/certificate sign (“Client” . $myserver) name=(“Client” . $myserver) ca=MYCA}
2:Export the certificate for backup
3:configure server
4:create user
5:Enable SSTP service
6:Upload the certificate to the client, import the certificate
7:create sstp client
The first three connections are normal, but the fourth client fails to connect, and the latter cannot be connected either.
If one of the normal connections is disabled, the fourth client can connect
I want all clients to be able to connect, how to solve it
(In addition, I tested the pptp service, all are normal, all can be connected, except for the sstp service, a routeros terminal can only connect to three clients, if you add another terminal, you can connect to three clients)

Ok, I edited, keep asking for help

:slight_smile: ,OK,I re-edited, this is more detailed

I am not sure what you are trying to do here, but it looks like you have 1 server MikroTik device and 1 client MikroTik device and you are trying to create multiple VPN connections between them.

I think (from what you’ve written) that you are trying to create a Site-To-Site VPN connection. If that’s the case, you only need to have 1 of the SSTP connections running and then configure the routing so that the sites can talk to each other.
