Set up IP tables on Asus RT-AC88U running DD-WRT v3.0-r30356 std (08/04/16)
Please read two attachments and acknowledge these.
The first shows the current settings; everything works (ie public can access website and private can still operate) but there's no control over which devices can access other devices on the network - private is not private!
The second attachment shows my guess at what the functionality the IP tables should permit - please correct if this has errors.
Private network: all ethernet ports, plus o-event wifi; 192.168.10.x
Public network: o-public wifi; 192.168.20.x
Webserver sits on [login to view URL]; anyone connected to o-public is directed to the website hosted on [login to view URL]
Anyone connected to o-public can’t access other devices connected to o-public and can’t access any devices on o-event & ethernet (protect from each other and protect private network)
Any device on private network (o-event) can access other devices connected to private network (like a normal network)
