Chapter 12 Policy
Policy
Every packet has to be detected if it corresponds with Policy or not when it
passes the SMC BR21VPN. When the conditions correspond with certain policy,
it will pass the SMC BR21VPN by the setting of Policy without being detected by
other policy. But if the packet cannot correspond with any Policy, the packet will
be intercepted.
The parameter of the policy includes Source Address, Destination Address,
Service, Action, WAN Port, Traffic Log, Statistics, Content Blocking, Anti-Virus,
Authentication User, Schedule, Alarm Threshold, Trunk, Max. Concurrent
Sessions, and QoS. Control policies decide whether packets from different
network objects, network services, and applications are able to pass through the
SMC BR21VPN.
How to use Policy?
The device uses policies to filter packets. The policy settings are: source
address, destination address, services, permission, packet log, packet statistics,
and flow alarm. Based on its source addresses, a packet can be categorized
into:
(1)
Outgoing:
The source IP is in LAN network; the destination is in WAN
network. The system manager can set all the policy rules of Outgoing
packets in this function
(2)
Incoming:
The source IP is in WAN network; the destination is in LAN
network. (For example: Mapped IP, Virtual Server) The system manager
can set all the policy rules of Incoming packets in this function
(3)
WAN to DMZ:
The source IP is in WAN network; the destination is in
DMZ network. (For example: Mapped IP, Virtual Server) The system
manager can set all the policy rules of WAN to DMZ packets in this
function
