User's Guide

Firewall

A complete list of active Firewall rules is displayed in this menu, with real time data

regarding network traffic handled by these rules.

IPV4 and IPV6 are separately displayed by selecting the Tab at the top of the main

window.

Firewall rules are shown at the WAN and LAN level for Inputs, Outputs, Forwarding,

Rejection, and Quality of Service (QoS). Rules are sorted into Tables by FILTER / NAT /

MANGLE / RAW. Firewall NAT tables apply to IPv4 only.

Each rule entry describes the rule via the target, protocol, input interface, output

interface, source IP address or IP address range, and destination IP address or IP address

range. Each rule entry also displays options and comments, if any. Finally, each rule entry

displays the number of packets and amount of traffic handled by the rule.

Buttons at the top right of the screen allow the user to

• Hide empty chains: removes chains with no firewall rules from the display

• Reset Counters: to set all traffic counters to zero

• Restart Firewall: restarts all firewall rule chains
