Device Compatibility and Network Tunnels
Secure Access connects and secures traffic from IPsec tunnels established by various network devices. A network device must have the capability to configure an IPsec (Internet Protocol Security) IKEv2 (Internet Key Exchange, version 2) tunnel and connect to Secure Access.

IPsec Tunnel Requirements
IPsec tunnels for Secure Access must have an MTU that is no larger than 1390 bytes. Secure Access automatically clamps the TCP MSS to 1350 or below.
Fragmented packets in underlay or overlay are dropped. Slightly larger MTU and MSS may work depending on your IPsec configuration. For more information about establishing tunnels to Secure Access, see the tunnel configuration topics found in Network Tunnel Configuration.
Supported Devices for Setting Up IPsec Tunnels
Secure Access integrates with network devices that can create compatible IPsec tunnels. We provide guides to configure tunnels from various network devices. For devices where the setup is not documented, we cannot guarantee that the device can establish an IPsec tunnel to Secure Access.
