Hello Frank607! Happy to see you again. Thanks to respond me.
I am afraid to say that i am having still problem with establishing PPTP link between my MT's 450 RouterOS server and Windows XP Client. I have been done everything from documentation to configuring my PPTP server and XP client, but I can't establish PPTP link over INTERNET. I am able to access RB450 router while within the same attached LAN network through my Windows XP VPN client, but when i try to access RB450 from outside (over INTERNET) it drops the connection and when connecting process goes through its "verifying username and password" process it gives me an error message "Error 619 a connection to remote computer could not established, the port used for this connection was closed". Below is my configuration for PPTP link between MT 450 server and Windows XP client: I have also replaced my TP-LINK Modem by NeatGear, as TP-LINK don't have firewall rules and Dynamic DNS options available. I am able to access my Netgear DSL Modem+router over internet using "myhostname.dyndns.org:8080" address, but unable to access RB450 behind it.
Please check my configuration once again:

Please let me help in establishing this VPN connection and let me know where and what i am missing in the pptp configuration as i have been tried every configuration at both ends one-by-one with no PPTP link connectivity.
Once again any help will be appreciated greatly.
Thanks,
Paams
