How many clients can OpenVPN handle?
You can have 500 user accounts on your OpenVPN Access Server but only license it for 100 connections, and if 25 of those 500 users are connected then you can still connect 75 VPN tunnels with any of the 500 accounts.
Is OpenVPN a good VPN?
Unlike some other protocols, which work best or even only on certain operating systems, OpenVPN is set up for Mac, Android, Windows, Linux, iOS, and other platforms. This makes it a good choice if you want to run your VPN service on many different devices.
How to access remote network with OpenVPN?
Firewalls are turned off on the client and the server. I already asked this question on Network Engineering, but I was told ServerFault would be a better place for a problem like that. Routes on both sides of the VPN tunnel are required. Also IP Routing must be enabled on the server. For example on Windows 7:
Can you run OpenVPN client and server on the same machine?
I know there are possibilities on a Linux with the power of iptables but I do not really know if this is possible on a windows host. Having an OpenVPN TLS server and client on the same machine is possible (I’ve run this way under Ubuntu some time ago and don’t expect Windows makes a problem here).
What kind of authentication does OpenVPN use?
OpenVPN supports bidirectional authentication based on certificates, meaning that the client must authenticate the server certificate and the server must authenticate the client certificate before mutual trust is established.
How to avoid port conflicts between OpenVPN instances?
Simply set them to use different ports and virtual TAP-Win32 network cards. Preferably, configure the client instance to include nobind option so it uses a random, dynamic port. This will let you avoid port conflicts between instances easily (by default OpenVPN always binds to the default port 1194, even in client mode).
