If you have access to your network/router settings, we always recommend making sure that the ports CyberCat uses to operate aren’t being blocked.

Both macOS and iOS rely on the IKEv2/IPSec tunnelling protocol in order to connect.

They need UDP ports 500 and 4500 to be unblocked. Additionally, some routers have an “IPSec/IKEv2 Pass-Through” setting which opens the ports required for the VPN connection to operate.
