Unfotunately i have to solve this based on software i need to isolate each company to protect their info from others i have 3 companies and last one thing i need to see each company's traffic statics for long time periods. and i need to be able to limit their traffics that is all , but as i see on open vpn i could not group users.i have a cisco router which i could see the traffic of my servers external ip addresses so i decide to see them from there via giving each company one external ip to connect to internet . but i could not decide yet how to do it :) is there any body have an advice for me ?
I don't understand the role of a vpn here. Normally you would split address ranges and use firewalling (iptables on linux, access control lists on a cisco) on the interfaces where they connect. So your 3 companies would simply be split into different subnets with routing between them blocked on the device where they connect. A VPN is used if you need to connect things through a firewall that would otherwise block it - you might use that for your administrative access through the firewalls of for portions of companies in remote locations.
