• Characteristics these characteristics are listed in the following table and discussed in more detail below 183
• In the zywall usg interfaces are usually created on top of other interfaces only ethernet interfaces are created directly on top of the physical ports or port groups the relationships between interfaces are explained in the following table 183
• Interface required port interface 183
• Note the format of interface names other than the ethernet and ppp interface names is strict each name consists of 2 4 letters interface type followed by a number x for most interfaces x is limited by the maximum number of the type of interface for vlan interfaces x is defined by the number you enter in the vlan name field for example ethernet interface names are wan1 wan2 lan1 lan2 dmz vlan interfaces are vlan0 vlan1 vlan2 and so on 183
• Relationships between interfaces 183
• Table 83 ethernet ppp cellular vlan bridge and virtual interface characteristics 183
• Table 84 relationships between different types of interfaces 183
• The names of virtual interfaces are derived from the interfaces on which they are created for example virtual interfaces created on ethernet interface wan1 are called wan1 1 wan1 2 and so on virtual interfaces created on vlan interface vlan2 are called vlan2 1 vlan2 2 and so on you cannot specify the number after the colon in the web configurator it is a sequential number you can specify the number after the colon if you use the cli to set up a virtual interface 183

• Note if you create ip address objects based on an interface s ip address subnet or gateway the zywall usg automatically updates every rule or setting that uses the object whenever the interface s ip address settings change for example if you change the lan s ip address the zywall usg automatically updates the corresponding interface based lan subnet address object 189

• Like other interfaces virtual interfaces have an ip address subnet mask and gateway used to make routing decisions however you have to manually specify the ip address and subnet mask virtual interfaces cannot be dhcp clients like other interfaces you can restrict bandwidth through virtual interfaces but you cannot change the mtu the virtual interface uses the same mtu that the underlying interface uses unlike other interfaces virtual interfaces do not provide dhcp services and they do not verify that the gateway is available 254

• Authentication is used to guarantee the integrity but not the confidentiality of routing updates the transmitting router uses its key to encrypt the original message into a smaller message and the smaller message is transmitted with the original message the receiving router uses its key to encrypt the received message and then verifies that it matches the smaller message sent with it if the received message is verified then the receiving router accepts the updated routing information the transmitting and receiving routers must have the same key 288

• To counter this you could create a monitor profile that creates logs but all actions are disabled observe the logs over time and try to eliminate the causes of the false alarms when you re satisfied that they have been reduced to an acceptable level you could then create an in line profile whereby you configure appropriate actions to be taken when a packet matches a policy 374
• When creating adp profiles you may find that certain policies are triggering too many false positives or false negatives a false positive is when valid traffic is flagged as an attack a false negative is when invalid traffic is wrongly allowed to pass through the zywall usg as each network is different false positives and false negatives are common on initial adp deployment 374

• The first row allows the lan1 computer at ip address 172 6 to access the irc service on the wan 384
• The policy for the ceo must come before the policy that blocks all lan1 to wan irc traffic if the policy that blocks all lan1 to wan irc traffic came first the ceo s irc traffic would match that policy and the zywall usg would drop it and not check any other security policies 384

• The following table describes this screen 496
• You could create a new monitor profile that creates logs but all actions are disabled observe the logs over time and try to eliminate the causes of the false alarms when you re satisfied that they have been reduced to an acceptable level you could then create an inline profile whereby you configure appropriate actions to be taken when a packet matches a signature 496
• You may also find that certain signatures are triggering too many false positives or false negatives a false positive is when valid traffic is flagged as an attack a false negative is when invalid traffic is wrongly allowed to pass through the zywall usg as each network is different false positives and false negatives are common on initial idp deployment 496
• You may want to create a new profile if not all signatures in a base profile are applicable to your network in this case you should disable non applicable signatures so as to improve zywall usg idp processing efficiency 496
