Enabling Inbound Inspection

By default, SonicWall Gateway Anti-Virus inspects all inbound HTTP, FTP, IMAP, SMTP and POP3 traffic. Generic TCP Stream can optionally be enabled to inspect all other TCP-based traffic, such as non-standard ports of operation for SMTP and POP3, and IM and P2P protocols.

Within the context of SonicWall Gateway Anti-Virus, the Enable Inbound Inspection protocol traffic handling refers to:

• Non-SMTP traffic initiating from a Trusted, Wireless, or Encrypted zone destined to any zone.
• Non-SMTP traffic from a Public zone destined to an Untrusted zone.
• SMTP traffic initiating from a non-Trusted zone destined to a Trusted, Wireless, Encrypted, or Public zone.
• SMTP traffic initiating from a Trusted, Wireless, or Encrypted zone destined to a Trusted, Wireless, or Encrypted zone.
