Asymmetrical 

Route

Select this check box to have the Prestige firewall permit the use of triangle route 

topology on the network. See the appendix for more on triangle route topology.

Packet Direction

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

to DMZ, WAN to WAN/Router, WAN to LAN, WAN to DMZ, DMZ to DMZ/

Router, DMZ to LAN or DMZ to WAN).
Firewall rules are grouped based on the direction of travel of packets to which they 

apply. For example, LAN to LAN/Router means packets traveling from a 

computer/subnet on the LAN to either another computer/subnet on the LAN 

interface of the Prestige or the Prestige itself.

(allow the passage of) packets that are traveling in the selected direction.

Log

Select the check box to create a log (when the above action is taken) for packets 

that are traveling in the selected direction and do not match any of the rules below.
