Configuring Content Filtering - Motorola WS2000 - Wireless Switch - Network Management Device System Reference Manual

4.6 Configuring Content Filtering

Content filtering allows system administrators to block specific commands and URL extensions from going
out through the WS 2000 switch's WAN port. This feature allows blocking up to 10 files or URL extensions
and allows blocking of specific outbound HTTP, SMTP, and FTP requests.
To configure content filtering, select
menu.
1. Select the type of blocking for outbound HTTP requests. Check one or both of the options:
Web Proxy This selection blocks the use of web proxies by clients.
ActiveX This selection blocks all outgoing ActiveX requests by clients.
2. Enter the Outbound URL extensions to block. Do this by typing one URL extension or file name
(filename.ext) per line. Use an asterisk (*) as a wildcard in place of the filename to block all files with a
specific extension (for example *.exe).
3. Simple Mail Transport Protocol (SMTP) is the Internet standard for host-to- host mail transport. SMTP
generally operates over TCP on port 25. SMTP filtering allows the blocking of any or all outgoing SMTP
commands.Choose which SMTP commands to block from the list, by checking those commands to block.
HELO (Hello) This command is used to identify the SMTP sender to the SMTP receiver.
MAIL (Mail) This command initiates a mail transaction where mail data is delivered to one or
more mailboxes on the local server.
RCPT (Recipient) This command is used to identify a recipient of mail data.
DATA (Data) This command tells the SMTP receiver to treat the following information as mail
data from the sender.
QUIT (Quit) This command tells the receiver to respond with an OK reply and then terminate
communication with the sender.
SEND (Send) This command initiates a mail transaction where mail is sent to one or more
remote terminals.
