This is a VPN business with the following:
1. TCP, UDP and ICMP tunneling protocols using openvpn or any
2. Create a Windows based VPN GUI using .net/c/c++/phyton/ or anything
3. User authentication from database
4. Disclose all the necessary steps/scripts to setup tcp,udp,icmp tunneling in the SERVERS
5. give source code of GUI
I have a simple background in openvpn but I don't know how to do ICMP tunneling.
