Info

Overview IM, P2P & VoIP The FortiOS system comes with an impressive list of supported IM/P2P protocols and can be kept up-to-date with upgrades available for download from the Fortinet Distribution Network. There is no need to wait for firmware upgrade to stay ahead of the latest protocols. FortiOS also provides ways for you to deal with unknown protocols even before upgrades are available. Table 43 on page 460 lists the IM/P2P applications that are currently recognized by FortiOS. The table includes the decoders, the applications associated with the decoders and the location of the decoders in the FortiGate interface. Note: Applications in Table 43 on page 460 marked as bold can connect to multiple P2P networks. Turning on IM and P2P decoders and signatures will help improve IPS performance. For example, if you want to use IPS, but you do not want to block IM or P2P applications, you should leave IM/P2P decoders and signatures enabled. Normally, if you turn off other signatures, the performance will be better, but for IM/P2P, it's the opposite.

The FortiGate unit allows you to configure your unit in the way that best serves your needs. How to enable and disable IM/P2P options This section will tell you the four main locations to enable or disable the IM/P2P options. This section includes how to enable predefined signatures, custom signatures and unknown user policies. To enable predefined IM/P2P signatures in intrusion protection 1 Go to Intrusion Protection > Signatures > Predefined. 2 Use the signature group filter to search for the IM and P2P signatures. 3 Enable the signature by selecting the Enable box. 4 Enable logging for a signature by selecting the Logging box. 5 In the row that corresponds to the signature you want to edit, select the Edit icon. 6 Set the action and severity. 7 Select OK. To create custom IM/P2P signatures for unknown protocols 1 Go to Intrusion Protection > Signature > Custom > Create New. FortiGate Version 3.0 MR5 Administration Guide 01-30005-0203-20070830 461
