MacOS – Raise maximum connection limit for Internet Sharing

OS-X treats a VPN connection as a totally separate connection from the device (airport, ethernet) it is transported on. So when you turned on your VPN, your airport or ethernet connection was no longer active.

If you want to share the VPN connection, you have to set up sharing for it the same way you did for your primary, non-VPN connection. They behave totally separately, for sharing purposes.

To try to make things clear let's say you have 2 Mac named:

• Alex
• Bob

Here is the scheme of your small home network :

Internet --- USB --- Alex --- WLAN --- Bob

If when Bob try to join the wireless network (AirPort or WI-Fi or better WLAN) initiated from Alex, it gets an immediate rejection, this may be due to a network access with the wrong security setting.

To check this hypothesis, on Bob, simply go within:

System Preferences… > Network > WiFi > Advanced…

and look at the column Security.

If it is anything else than WPA2 Personal, double click on this network setting to fix it.

If it is already WPA2 Personal, double click on this network setting to check if the registered password is OK.
