# Set up Dynamic DNS for Cellular Gateways

Cellular gateways can act as a site-to-site IPsec IKEv2 VPN client. The public IP address for a VPN client is required to set up the IPsec tunnel. Setting up Dynamic DNS will ensure the VPN server always has access to the dynamically assigned public IP address for the VPN client (GC31/GC31-E).
