Question:

What ports need to be open in my firewall for Sophos for Marshal?

Information:

Sophos for Marshal requires Engine and IDE updates to maintain current virus protection.

By default, the Sophos for Marshal updater uses a direct HTTP or HTTPS connection to download these updates from Marshal.

• You can also use a proxy server.

For more information about the options, see Help for the Sophos for Marshal configuration tool.

The table below details the various ports used by Sophos for Marshal for direct connections. These ports must be available on every processing server where the Sophos for Marshal package is installed.

If you use an active web filtering device upstream of the processing server (such as WebMarshal), you must configure it to pass this traffic.
