I want to install and configure several routers with OpenWRT. The problem is that when I have done a "Restore" of previously generated backup the VPN of my router don't work.
I have several Linksys WRT3200ACM routers.
I configured a (Master router) manually with VPN and a number of settings. (This take some time, ... and a long time for me)
When I got everything working of the VPN,
I make a backup (Generate archive).
Then I install exactly the same version of OpenWRT firmware on another Linksys WRT3200ACM.
I then do a "Restore" by a previously generated backup.
I am using the one that I previusly has made from my "Master router".
Then the new (clone or copy router ) router reboots.
But my configurations and my VPN settings is NOT working.
I can access the router but the VPN is not Working.
WHY .... ???
I am doing something wrong but I don't know what is wrong and why.
On some devices you will get device specific data (mostly MAC addresses) in your configuration, restoring this on multple devices will cause havoc. Furthermore it's not guaranteed that your exported configuration contains all files necessary for all installed services (e.g. VPN profiles and everything needed for the SSL certificate handling), you will need check that manually and extend sysupgrade.conf accordingly.
