Mass adding Pass Through MAC information

[alltime]

I am reconfiguring my Captive portal, so I'll be creating a new zone then deleting the original.
Is the file/database containing the pass through mac information in plain text? This would be helpful in order to avoid me having to enter each address one-by-one.

It's all in the config.xml, you can take a backup from Diag > Backup/Restore and copy/paste it however you want to the new zone. Then restore the edited config.
