Question :

How do I manually add a VPN profile on an iPhone for an IKEv2 VPN connection with Nebula Firewall?

Answer :

The user can not only import the .mobileconfig file downloaded from the firewall to the iPhone's IKEv2 VPN connection but also manually add an IKEv2 VPN profile on the iPhone. For example, the steps below were tested on iOS 18.1.1 and a USG Flex 100 firewall with 5.39 patch 1 firmware:

STEP1. Navigate to Settings > VPN > Add VPN Configuration > To add an IKEv2 VPN profile, input the Description, Server's IP address, and Remote ID (which should be the same as the Server's IP address), along with the Username and Password.

To verify the IKEv2 VPN connection:
Select the corresponding IKEv2 VPN profile and establish the VPN connection successfully.
