hi, sorry for bad english :drug:

example:

but i need to connect to this vpn from only specific ip addresses. example 2: its my external ip xx.xx.xx.xx its another external ip yy.yy.yy.yy, i need to connect this vpn from only xx.xx.xx.xx and not connect from yy.yy.yy.yy.

ban, warn, kill me, but after than tell me what can i do xD

Make /ip firewall filter rule in chain=input.

Allow 1723 PPTP for specific address ,
/ip firewall filter add chain=input action=drop protocol=tcp src-address=!your_IP dst-port=1723
your_IP - is allowed IP address to establish PPTP connection.
