I have a pptp server (3.1.1.3) that allows technicians to gain access to my network. I have a particular user who I am granted a static ip address to (3.1.1.200). I only want this user to have access to, for instance, servers 3.1.1.10 and 3.1.1.20. How do I, using iptables on 3.1.1.3, restrict this user to only have access to .10 and .20? Any assistance will be greatly appreciated. Thanks in advance, Hu
