    restricting PPTP users

    Dear All,
    I have a Ubuntu PPTP vpn server and its working fine
    I have about 8 users that are using vpn.
    each user should be able to access their own server or servers

    now the issues I am having is how do I restrict a particular user to access only his server and not even able to ping or reach the other server

    is it possible on the VPN server that if the user logs in a userA he is allowed to access only server1 and server2 and not server 3 and similarly userB allowed to access server 2 and server 3 but not server 1

    appreciate your kind help

    regards

    simon

    Using pptp is not a good choice anymore.
    Please read the following article:

    Maybe it is better to choose ltp or ipsec?

    About the security case. Make sure that only the user account of a particular user is enabledon the server where he/her is allowed to logon.

    Hello



    Whether your using PPTP or L2TP or some other method, I still think your stuck with limiting network access to servers based on who the user is.

    I would recommend reading bodhizazen's (staff emeritus at the UF) excellent blog


    I figure your best bet is to set up users in groups.
    This way you can control the groups access using iptables or ufw
    Go to the part in the blog which discusses limiting network access based on groups
    You can tell a man who boozes by the company he chooses, as the pig got up and slowly walked away.
