A pptp vpn has been setup on an ubuntu server. The VPN server is used by my voip clients in UAE where free internet is blocked. The VPN server's inernet connection is used to bypass the ISP blocking.
The vpn server is already configured and working but it currently allows traffic to any voip server (port 5060) which means that my competitors are also able to use my vpn server.
The project requirement is to change the setting so that traffic is only allowed to the following services. No other website or voip traffic should be allowed via my vpn server.
My voip server([url removed, login to view]) on port 5060.
My Website [url removed, login to view]
As part of the project requirement, you will also have to document the process of adding/ modifying and deleting new IP addresses.
Hi. It can be easily done with iptables. I can also write a script for you to ease adding/deleting of ips, of course I'll give you documentation. Price is negotiable.
