Importing a configuration file during Sophos firewall upgrade produces an error

  • Article ID: 63954
  • Updated: 08 Oct 2009

Issue
If you export a Sophos firewall .conf file and attempt to import and merge it into an existing configuration  it may produces an error message, for example: 

A duplicate entry was attempted to be added to UniqueUnorderedList

This issue is usually only seen if you try to merge a configuration more than once.

What to do

When you import the.conf file you must overwrite the existing one rather than merge it.
  1. On the General Tab, select the Import button.
  2. Select what you want to Import.
  3. From the options displayed, select the option to overwrite the current configuration.

Technical background
This is a known issue, it arises from the way in which the Sophos firewall renames rules.
