Pretty close, ideally you should be checking for how the station was heard: direct, one hop, two hops, etc, and only IGate traffic to those within however many hops your output is configured to send outgoing packets. You might also raise the timeout from 30 minutes. If a station only beacons every 30 minutes there will be a loss of coverage for those 30 minutes every time a packet is not heard by you. Two hours is probably better. Stations that leave your network still time out pretty quickly and there is less risk of not IGating something you should have.
