Chapter 15 Firewall

AMG1312-T Series User’s Guide

The following table describes the labels in this screen.

Security > Firewall > Default Action

Packet Direction

This is the direction of travel of packets (LAN to Router, LAN to WAN, WAN to Router, 
WAN to LAN).

Firewall rules are grouped based on the direction of travel of packets to which they apply. 
For example, LAN to Router means packets traveling from a computer/subnet on the 
LAN to the AMG1312-T Series itself. 

Default Action

Use the drop-down list boxes to select the default action that the firewall is to take on 
packets that are traveling in the selected direction and do not match any of the firewall 
rules. 

Select Drop to silently discard the packets without sending a TCP reset packet or an ICMP 
destination-unreachable message to the sender.

Select Reject to deny the packets and send a TCP reset packet (for a TCP packet) or an 
ICMP destination-unreachable message (for a UDP packet) to the sender.

Select Permit to allow the passage of the packets.
