[clug] help network not working after upgrade to Fedora 22 (urgent)

[Alex Satrapa]

Absolutely yes, you should have a firewall active on any machine with an active network interface. That firewall should work to protect the Internet from your machine as well as protecting your machine from the Internet.

There are about as many firewall options as there are sysadmins. One that I like is “Firehol”: http://firehol.org/#firehol

This “Domain Specific Language” tries to help you build firewalls by providing a vocabulary around the services you’re trying to enable. This removes you one or two levels from iptables where you have to remember to set up incoming, outgoing, and through-traffic rules for all services.

Be aware that FireHOL is based on a very strict firewall concept of denying everything that isn’t explicitly allowed. It has a built-in safeguard of requiring you to type “commit” after you’ve set up new rules, in order to reduce the risk of accidentally locking yourself out of SSH connections (and accidentally shutting down the SSH connection you are currently using).
