# Configuration Deka VPN: IPSec

The **IPSec** section allows you to configure VPN connections using the IPSec protocol. If no IPSec configuration exists, the page displays the [**Create IPSec**](/deka-vpn-gpu/configuration-deka-vpn-ipsec/create-ipsec.md) option. After an IPSec configuration is created, the page displays the following sections:

* [**IPSec Detail**](/deka-vpn-gpu/configuration-deka-vpn-ipsec/ipsec-detail.md) provides access to view basic IPSec configuration.
* [**IPSec Tunnel**](/deka-vpn-gpu/configuration-deka-vpn-ipsec/ipsec-tunnel.md) allows management of tunnel settings such as pre-shared keys, Phase 2, and encryption algorithms.
* [**IPSec Connection**](/deka-vpn-gpu/configuration-deka-vpn-ipsec/ipsec-connection.md) displays detailed information about IPSec connections.

Each tab provides specific options to configure and manage IPSec-based VPNs.
