Understanding iOS Settings and Protocols

Authors list

Now that you have the VPN installed on your iOS devices, you may be interested in the settings and features available in the iOS application. 


To access the iOS settings select the (3) horizontal lines in the top left corner. 


Here you will be able to access several options such as: Region Selection, Account, Settings, Log out, and more. 


Once you are in the Settings menu you will be able to access and change several features depending on the protocols that your application is connecting to. Below we outline what each protocol’s settings are available and what they do.  


The Protocols that you can connect to are: WireGuard, OpenVPN and IKEv2 


The protocol selected will change the settings that you can select. 


IPsec (IKEv2) settings: IKEv2 is an advanced VPN protocol that provides a balance between security and speed by using the UDP socket and port 500 for lower latency communication. Additionally, you are able to toggle the Data encryption level as well as the Handshake. 


OpenVPN settings:   OpenVPN gives the most flexibility when encountering connection issues as different Sockets and Port combinations can resolve them. Not only are you able to toggle your encryption settings, but you have the option to enable the 'Use small packets' feature.  


WireGuard settings: WireGuard which is optimized to be the best pre-configured option for speed and security, connects over the TCP socket with port 1337 in use. Similar to our other pre-configured option, IPsec, you have the basic settings to chose from with the exception of the ability to change your encryption settings. 


Please See below for the Setting Descriptions
