Firewall
From MEPIS Documentation Wiki
(Redirected from Firewalls)
[edit]
Summary
A firewall is a device or application used to filter data packets from incoming or outgoing network traffic, usually based upon the IP address or type of service (literally, the port number).
Most firewall programs are merely front ends for Netfilter/iptables, the network filtering module in recent Linux kernels. So, the real difference between different firewalls is how the interface works and what options are available.

Ways to Configure Firewalls
- Guarddog -- default firewall installed with MEPIS. It is actually a GUI configuration tool for iptables.
- Firestarter -- alternative to Guarddog, considered easier by many users.
- Enabling Firewall for P2P Applications -- Gnutella, Frostwire, Limewire, etc.
- Webmin: Web based system administration tool. Contains a module to configure the firewall and routing capabilities of the kernel. Very flexible and powerful but somewhat complex.
- Kmyfirewall: a KDE-based firewall tool designed to be relatively easy while providing full-featured control of iptables.
- Iptables manual configuration
