Chapter 25
Specific settings and troubleshooting
This chapter provides description of advanced features and specific configurations of the
firewall. It also includes helpful guidelines for solving of issues which might occur when
you use Kerio Control in your network.
25.1 Configuration Backup and Transfer
If you need to reinstall the firewall’s operating system (e.g. in case of new hardware
installation), you can easily back up your Kerio Control configuration including local user
accounts and possibly also SSL certificates. This backup can be later used for recovery of this
configuration in your new installation of Kerio Control. This may save significant amount of
your time as well as help you avoid solution of problems you have already figured out.
To export or import configuration, go to the Administration web interface (see chapter 3) and
click on the corresponding link right in the welcome page.
Configuration export
Configuration is exported to a .tgz package (the tar archive compressed by gzip) which
includes all the key Kerio Control configuration files. Optionally, it is possible to include the
web interface’s VPN server’s and SSL-VPN server’s SSL certificates in the package. Exported
configuration does not include Kerio Control license key.
Configuration import
To import configuration, simply browse for or enter the path to the corresponding file which
includes the exported configuration (with the .tgz extension).
If network interfaces have been changed since the export took place (e.g. in case of exchange
of a defective network adapter) or if the configuration is imported from another computer,
Kerio Control will attempt to pair the imported network interfaces with the real interfaces on
the machine. This pairing can be customized — you can match each network interface from
the imported configuration with one interface of the firewall or leave it unpaired.
If network interfaces cannot be simply paired, it is desirable to check and possibly edit
interface group settings (see chapter 5) and/or traffic rules (see chapter 7) after completion of
the configuration import.
