Bodging together a guest network?

[platypus]

I've got an asus rt56nu (and two dlink 615s running dd-wrt as wireless APs/boosters) which doesn't have a guest network feature (unless its unlockable with custom firmware??). I'd like to have a guest network for visitors, can I bodge something together with the 3 routers?

The DDWRT routers support guest networks.

Would that work with them having routing/dhcp off though?

@KIA I've looked at that before. I take it that firmware enables guest network on the 56nu, can't seem to find a list of features?

Yes. Are you already running the latest official ASUS firmware?

Yep updated earlier this week.
