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 169
(4) LAN to DMZ: The source IP is in LAN network; the destination is in DMZ network. The system manager can set all the policy rules of LAN to DMZ packets in this function (5) DMZ to LAN: The source IP is in DMZ network; the destination is in LAN network. The system manager can set all the policy rules of DMZ to LAN packets in this function (6) DMZ to WAN: The source IP is in DMZ network; the destination is in WAN network. The system manager can set all the policy rules of DMZ to WAN packets in this function All the packets that go through SMC BR21VPN must pass the policy permission (except VPN). Therefore, the LAN, WAN, and DMZ network have to set the applicable policy when establish network connection. 170
