What are the different VPN protocols and their compatibility?

What are the different VPN protocols and how do they compare in terms of compatibility?

There are several VPN protocols like OpenVPN, L2TP/IPsec, PPTP, and IKEv2. OpenVPN is widely compatible across platforms, while PPTP is less secure but easier to set up. L2TP/IPsec offers better security but can be blocked by some firewalls. IKEv2 is great for mobile devices due to its ability to reconnect quickly.

Which protocol is the best for streaming?

For streaming, OpenVPN is often recommended due to its balance of speed and security. However, some users prefer IKEv2 for its fast reconnection capabilities.

Are there any protocols that work better in restrictive networks?

Yes, OpenVPN is known for its ability to bypass firewalls, especially when configured to use TCP over port 443. This makes it effective in restrictive networks.

What about security levels among these protocols?

In terms of security, OpenVPN and IKEv2 are considered the most secure, while PPTP is the least secure. L2TP/IPsec offers a good balance but can be vulnerable if not properly configured.
