Proxy actions to redirect traffic

The TCP-UDP-proxy can pass HTTP, HTTPS, SIP, FTP, IMAP, POP3, and SMTP traffic to proxy policies that you have already created when this traffic is sent over non-standard ports.

TCP-UDP proxy action support for IMAP is available in Fireware OS v12.1 and higher. TCP-UDP proxy action support for POP3 and SMTP is available in Fireware OS v12.2 and higher.

For each of these protocols, from the adjacent drop-down list, select the proxy action to use to manage this traffic.

If you do not want your Firebox to use a proxy action to filter a protocol, select Allow or Deny from the adjacent drop-down list.

To make sure that your Firebox operates correctly, you cannot select the Allow option for the FTP protocol.

Redirect IMAPS/POP3S/SMTPS

These options are available only when IMAP, POP3, or SMTP proxy actions are selected. Configure the TLS settings in the selected proxy action. For more information, see IMAP-Proxy: TLS, POP3-Proxy: TLS, and SMTP-Proxy: TLS.

The selected proxy actions apply only to TLS/SSL requests on these ports:

  • IMAP: Port 993
  • POP3: Port 995
  • SMTP: Port 465

The HTTPS proxy action applies to TLS/SSL requests on all other ports.

Other Protocols

Specifies the action to take for connections sent over non-standard ports that the TCP-UDP proxy does not identify as HTTP, HTTPS, SIP, FTP, IMAP, POP3, or SMTP traffic. Select Allow or Deny from the drop-down list.
