•QoS profile. You can define QoS profiles and then apply them to outbound rules to regulate the priority of traffic. For information about how to define QoS profiles, see Create Quality of Service Profiles on page 169.

•Traffic Meter profile. You can define traffic meter profiles and then apply them to outbound rules to measure traffic and to block traffic that exceeds a threshold. For information about how to define traffic meter profiles, see Create Traffic Meter Profiles on page 174.

•Bandwidth profile. You can define bandwidth profiles and then apply them to outbound rules to limit traffic. For information about how to define bandwidth profiles, see Create Bandwidth Profiles on page 171. (You cannot apply bandwidth profiles to DMZ WAN outbound rules.)

Content Filtering

If you want to reduce traffic by preventing undesired emails from reaching their destinations or by preventing access to certain sites on the Internet, you can use the UTM’s content-filtering feature. By default, this feature is disabled; all requested traffic from any website is allowed except for web content categories that are mentioned in Default Email and Web Scan Settings on page 193.

•Email content filtering. To reduce incoming email traffic, you can block emails with large attachments, reject emails based on keywords, file extensions, or file names, and set spam protection rules. There are several ways you can reduce undesired email traffic:

-Setting the size of email files to be scanned. Scanning large email files requires network resources and might slow down traffic. You can specify the maximum size of the files or messages that are scanned, and if files that exceed the maximum size are skipped (which might compromise security) or blocked. For more information, see Customize Email Antivirus and Notification Settings on page 196.

-Keyword, file extension, and file name blocking. You can reject emails based on keywords in the subject line, file type of the attachment, and file name of the attachment. For more information, see Email Content Filtering on page 199.

-Protecting against spam. Set up spam protection to prevent spam from using up valuable bandwidth. For more information, see Protect Against Email Spam on page 202.

•Web content filtering. The UTM provides extensive methods to filter web content in order to reduce traffic:

-Web category blocking. You can block entire web categories because their content is undesired, offensive, or not relevant, or simply to reduce traffic. For more information, see Configure Web Content Filtering on page 218.

-Keyword and file extension blocking. You can specify words that, should they appear in the website name (URL), file extension, or newsgroup name, cause that site, file, or newsgroup to be blocked by the UTM. For more information, see Configure Web Content Filtering on page 218.

-URL blocking. You can specify up to 200 URLs that are blocked by the UTM. For more information, see Configure Web URL Filtering on page 224.
