Thanks for that,
When the <xcatmaster> started to get supported for the gateway option, I
tried this option on other parameters in the networks table, but that was
unsupported.
Could you clarify, which columns are supported, and which are not. As I
tried this under tftpserver, and that didn't quite go as planned.
regards,
Arif
