[mili_sms]

Hi , I am using Pf sense as my primary firewall in my Organization, Now we have decided to shift our designers on every monthly basis to different location computers. Now here i have a problem I am able to provide internet access to certain users from getting to know about their computer IP. Each time a users moves i need to do it, Kindly let me know if you have something based on user access list , Like user based Internet access from Active Directory.
