Good day!
I am a certified network engineer (MTCTCE/MTCNA) having over 10 years of experience in configuring, maintaining and troubleshooting of enterprise network devices, VPNs, and Linux servers.
I can help You qualitatively, because I know many types of VPN. As I know, some types (Cisco SSL and OpenVPN) of VPN are blocked in Egypt, but SSH tunnel work always and everywhere.
Do You plan to use VPS as VPN server?
