Incorrect editing of the firewall rules may cause security risks! A good understanding of how firewall rules work can be achieved by marking checkboxes on the Security Profile pages, and examining what new rules they add to the firewall rules. text/html 2010-11-04T13:20:48+02:00 http://wiki.igmanual.com/doku.php?id=firewall:example_2&rev=1288873248&do=diff Firewall rule tutorial example 2: :!: This description is addressed to advanced users only.

Incorrect editing of the firewall rules may cause security risks! As you can see by examples 2 and 3, it is usually the outside interface that handles the flows. But all interfaces are capable of creating flows. text/html 2010-10-29T14:46:52+02:00 http://wiki.igmanual.com/doku.php?id=firewall:flows&rev=1288356412&do=diff The firewall in Internet Gate uses flows to be able to stateful inspect data streams. Each new data stream to be inspected uses one flow to track what state the data stream is in. If the data stream is bi-directional then two flows are used – one in each direction. text/html 2010-11-01T12:53:02+02:00 http://wiki.igmanual.com/doku.php?id=firewall:security_profiles&rev=1288612382&do=diff The Internet Gate uses security profiles to store its security settings. The security profiles provide an easy way for users, without previous knowledge about network security, to administrate the firewall. The predefined security profiles are prepared with support for the most commonly used applications, games and services. The default settings of the security profiles will be sufficient for most users. By changing between the profiles, you control what traffic is allowed to pass. text/html 2010-11-15T14:43:07+02:00 http://wiki.igmanual.com/doku.php?id=firewall:start&rev=1289828587&do=diff The Internet Gate contains a powerful firewall protecting your computers from the Internet. Firewall Overview What is a firewall? The firewall works like a barrier that keeps destructive forces away from your computers. It guarantees that only allowed traffic passes in and out between the two networks.

This means that the rest of the text is only relevant for the Internet Gate unless otherwise noted. The text will loosely refer to a unit of data transmitted on the network as a packet when it would be more correct to use, for example, frame in some situations. text/html 2010-11-04T11:47:57+02:00 http://wiki.igmanual.com/doku.php?id=firewall:tutorial&rev=1288867677&do=diff :!: This description is addressed to advanced users only. Incorrect editing of the firewall rules may cause security risks! Editing the firewall rules manually allows greater control of what is allowed through the firewall, but is also much more complicated than using the Security Profile pages.
