I have a WiFi device that I want to be able to connect to other machines on my network, but not to the Internet. I have an ASUS RT-N56U Router. I have looked through the router settings and searched the internet but haven't found an answer. Any ideas?

Edit1: I found this: enter image description here

  • does your firewall allow egress filtering? – Frank Thomas Jun 18 '14 at 16:53
  • I'm not sure, I'll check when I get home from work – Awk34 Jun 18 '14 at 17:08
  • I would also look for access restrictions or parental controls which could be used to restrict access. – heavyd Jun 18 '14 at 17:10
  • Check out Edit1. So Source would be the device's IP. Port range would probably be 0-65535 for both. Might have to make a TCP and UDP rule. Should that work? – Awk34 Jun 18 '14 at 17:32

If you configure the restricted device manually, without configuring a default route/gateway, or setting it to 127.0.0.1, it will allow the device to communicate on the LAN only.

  • I don't really know how to... Have you attempted to configure that device manually? – Nevin Williams Jun 19 '14 at 4:31
  • I have, but I do not trust the device. That is why I want to do it via the router. – Awk34 Jun 19 '14 at 14:07

Would it be possible for you to set the device up with a static IP without a gateway address? This would solve your problem immediately. Everything and anything would be reachable on the local network, but the device wouldn't know how to reach anything on the internet.
