Use certificate in IPSec VPN

Hi everyone,

I am administrating an AirLink device which has dynamical IP and I want to stablish a IPSec connection between this AirLink and a checkpoint device. The problem is that checkpoint device needs to authenticate remote dynamical IP devices with a self-signed certificate, so I need to install/use this certificate in the AirLink device.

After look for a solution, I have no idea about how can I do that in AirLink device. Could someone help me?

Thanks beforehand,
