How to configure VPN on my Microtik?

Hi guys.

I have ip, port, login and password from proxy-provider.
How to configure this proxy interface on my router?

I’ve readed a lot of manuals but I can`t find proxy setup with some specific port, login and password.
Can somebody help me?

You need to know the technology of your provider. RouterOS offers you

# L2TP client
/interface l2tp-client add name="my-provider" connect-to="ip" user="myusername" password="mypassword"
# Open VPN client
/interface ovpn-client add... #same options
# SSTP client
/interface sstp-client add... #same options
# PPTO client
/interface pptp-client add...  #same options

This pseudocode is for the terminal. In the WebFig interface they are under Interfaces → Add new drop down

They all are based on PPP, and share the /ppp profile if they gave you any special ppp options, etc.
They also have additional parameters, depending on thecnology: certificates, ipsec stuff…

You can also manufacture yourself some other vpn alternatives, using things like ipsec, ipip tunnels, eoip, … but the most commons are the ones above.

I have IP, PORT (65233), USERNAME, PASSWORD in Proxy settings, gived to me from provider.
I cant find any connection type in RouterOS, where I can specify specific PORT.
Only ip, username, pas - and its not working.

How to configure this proxy server WITH IP, PORT, USERNAME, PASSWORD for specific site list?
Can you provide step by step instruction please?
