When they access the webserver directly, they get blocked. But when they access via a proxy, I have no idea what...

    I learned that freebsd doesn't have a firewall running out of the box. I have no network knowledge. And as a desktop user, I find it a little bit unneccesary to learn little to moderate level of networking. Is there a GUI I can use to configure my fiewall to optimal settings?
