OmniAccess 5740 USG Specific Overview
• The default action for a filter is “deny”. However, you can change this to “permit”.
• By default OmniAccess 5740 USG, supports “stateful inspection”. However, you 
can change this to “stateless”.
• Filtering takes place only when filters are bound to interfaces - physical and 
virtual. If a virtual interface is created, the rules attached to the real interface is 
copied to the ruleset for the virtual interface. This can be modified. In the packet 
filter sequence, only the virtual interface ruleset will be used for the packets exiting 
from a virtual interface. The physical interface rules will have no effect on these 
packets.
• In contrast to other products, OmniAccess 5740 USG differentiates between the 
classification and the actions. The classification on OmniAccess 5740 USG is 
done by the use of match-lists and the actions are done by the use of filters.
