Firewall Setup

This task ensures that the system can be safely used as a network relay. This task protects an internal network from external public networks by setting up a dedicated system as a firewall, which is described in Firewall Systems. The firewall system separates two networks. In this situation, each network approaches the other network as untrusted. The firewall setup task disables the forwarding of Internet Protocol (IP) packets and hides routing information from the external network.

The firewall task runs at all security levels, but takes action only at the highest level. If you want to run ASET at high security, but find that your system does not require firewall protection, you can eliminate the firewall task by editing the asetenv file.

Any changes that are made are reported in the firewall.rpt file.
