MMS Scanning section of the New MMS Profile page

Content Filter

Select to filter messages based on matching the content of the mes- sage with the words or patterns in the selected web content filter list.

For information about adding a web content filter list, see the FortiGate CLI Reference.

Carrier Endpoint Block                 Select to add Carrier Endpoint Filtering in this MMS profile. Select the carrier endpoint filter list to apply it to the profile.

MMS Content Checksum              Select to add MMS Content Checksum in this MMS profile. Select the MMS content checksum list to apply it to the profile.

Pass Fragmented Messages        Select to pass fragmented MM3 and MM4 messages. Fragmented MMS messages cannot be scanned for viruses. If you do not select these options, fragmented MM3 and MM4 message are blocked.

Comfort Clients

Select client comforting for MM1 and MM7 sessions.

Since MM1 and MM7 messages use HTTP, MM1 and MM7 client com- forting operates like HTTP client comforting.

Comfort Servers                             Select server comforting for each protocol.

Interval (1-900 seconds)

Similar to client comforting, you can use server comforting to prevent server connection timeouts that can occur while waiting for the unit to buffer and scan large POST requests from slow clients.

Enter the time in seconds before client and server comforting starts after the download has begun, and the time between sending sub- sequent data.

Amount (1-10240 bytes)

The number of bytes sent by client or server comforting at each interval.

Select Block or Pass for files and email messages exceeding con- figured thresholds for each protocol.

Oversized MMS Message

The oversize threshold refers to the final size of the message, including attachments, after encoding by the client. Clients can use a variety of encoding types; some result in larger file sizes than the original attach- ment. As a result, a file may be blocked or logged as oversized even if the attachment is several megabytes smaller than the oversize threshold.
