Switch on SSH (inside/outside)?
SSH is a secure telnet client to access your FSG. If you do not know what that means, you do not need it. If you wish to have access to your FSG via SSH from anywhere in the world, switch on SSH access to the outside. If you do not need to reach your FSG via SSH from everywhere, but only from your home, switch on SSH from the inside. If you do not need SSH, or do not know what it is, switch it off. Be careful! When you can reach your FSG, others can too. Make sure you only use users with a password and delete the guest account if you switch this on to the outside.
