This section describes the setup necessary to provide wireless access to NintendoDS without compromising the internal security of the Intranet. Unfortunately it is not possible to allow wireless access to Nintendo DS by creating special firewall rules as you have to allow any traffic from/to almost every port everywhere. Additionally Nintendo DS does only provide WEP security.

We have to make sure that the NDS WLAN is only active if necessary. Therefore NDS WLAN is setup to be disabled upon restart of the NDS router and has to be enabled manually by pushing the SES/AOSS button. As an additional security measure the NDS WLAN is disabled at 1:00 AM everday to make sure it does not run in case you forget to disable it.

You need:

• A web browser
• 2 routers (i.e. Linksys WRT54G)
• All routers should have Tomato firmware installed (http://www.polarcloud.com/tomato)
