Firewall Configuration

A firewall is a means of restricting dialled access to and from a network, particularly at its interface with the Internet. The IPNC has a firewall with default settings that allow local users access to the outside world using most TCP/IP protocols, but stops any unsolicited access from the outside world to your subnet. When a permitted outgoing session starts it punches a hole in the firewall. This then allows traffic to flow in both directions. When the session ends the hole is sealed. A firewall can be specified for both User and Service profiles.

The Standard Firewall Tab

Use the following menu to set up the required firewall profile.

Name: The name of every firewall profile is made available in a drop-down list for Users and Services.

The Protocol radio buttons: A firewall can be configured to allow individual protocol sessions access as follows:

Drop: No sessions via selected protocol will be allowed through the firewall.

In: An incoming session can punch a hole in the firewall to allow traffic in both directions.

Out: An outgoing session can punch a hole in the firewall to allow traffic in both directions.

Bothway: Both incoming and outgoing sessions can punch a hole in the firewall to allow traffic in both directions

The protocols that can be managed in this way are:

File Transfer Protocol (FTP) - a TCP/IP application used for transferring files from one system to another

Telnet– used for remote access for diagnostic purposes.

Simple Mail Transfer Protocol (SMTP) – an email application.
