Astrill Setup Manual:Change Gateway and DNS on iOS
Change Gateway and DNS on iOS
Step 1 - On your iOS mobile device, tap on "Settings"
Step 2 - Tap on "Wi-Fi". Select the connected Wifi network and tap on the blue arrow icon on the right.
Step 3 - Enter the VPN Sharing IP address for ‘Router’ and ‘DNS’
Switch to "Static" tab and change the values of "Router" and "DNS" to the IP address you noted down earlier in VPN Sharing prompt here.
Your VPN Sharing IP address might be different in most cases. Don't just copy IP address from the example above, but get the correct IP address from VPN Sharing settings in Astrill application.
Note : Make sure the computer (sharing OpenVPN/StealthVPN connection) and the other device are connected to the same Wifi network/router. You can share with ANY number of devices if connected and configured as above on same network.
