About Pre-shared secret of site-to-site VPN

[checkkilaipoint]

Hello,

I would like to configure a site-to-site with using pre-shared secret between a CP 5200 R80.40 and a Watchguard firewall.

However I didn't know how to put the pre-shared secret to the VPN community. I have tried but failed.

Is there any guide about configuring  pre-shared secret in site-to-site VPN?
