When I rebooted it, Its IP changed to other and conflict with another server. I got the CLI and changed IP in /etc/sysconfig/network-scripts/ifcfg-eth0. Next I also changed IP address from UI to the same one.
And after next reboot It changes again to old IP.
I suppose, that I firstly set incorrect IP when I installed MWG appliance and I have changed it after installation.
There is string in /etc/sysconfig/network-scripts/ifcfg-eth0
### BEGIN AUTOGENERATED CONFIG
What I need to configure to ifcfg-eth0 becomes to get correct IP address. From what doesthis file get configuration?
