Dynamic & Static IP Address
Hellfire - 5/1/12 at 05:02 PM

I have a Belkin N wireless router at home which I think assigns dynamic IP addresses to all wireless devices as and when they access the network. What I would like to do (if possible) is assign static IP addresses to all (or maybe even just a few) wireless devices to enable me to block internet access for those devices. At present, I can determine which ones are accessing the wireless network and block the IP address but suspect that if I turn the router/device off and back on again, it may assign a different IP address.

Can anyone tell me if this is possible and maybe give me an idiots guide to do this please?

Hi Phil,

Are the devices which you want to block actually legitimate devices on your network? are they windows devices?

If so and you can configure the devices manually then a simple way of keeping them on your network but not allowing them to access the internet might be to give them an invalid DNS server address.

I don't think you can do what you want to do with the belkin router.

Cheers

Mark

Edit: have a look at P53 in the manual Manual link perhaps this is what you are looking for?

It is simple - but harder to explain step by step. The way I have set my network up is for the Router to assign IPs to devices that request them from 192.168.0.64 onwards - you can change the start address and number of "leases" on your router admin. All devices I want to have static IPs sit between 192.168.0.1 - 192.168.0.63. You can manually set a Windows IP in the Network Connection Properties Dialog under Internet Protocol Version 4. Uncheck obtain IP address automatically and enter what you'd like to use. You'll need to enter the subnet mask 255.255.255.0 and the IP of your router for the gateway. You'll also need to enter a couple of DNS addresses if you want web access on a static machine IP machine.

You should then be able to use the web access filtering by IP on the router to ensure they don't get any web access / block the relevant ports.

Thanks for the responses guys.

Mark, the devices are all legitimate devices which use the network and are a combination of laptops, smartphones, iPods & iPads.

Looks like I need the MAC addresses of the devices I want to deny internet access to and then I can set up a 'Deny' list on the router admin as described in the manual link. Or is it not that simple?

If you follow this route you will probably just deny the devices access to the Wireless network therefore negating any network ability at all.

I presume your are wanting file sharing and printing but no web access.

On most routers you can set time rules for web access if that's what your looking for - but It'll be IP based.

ok if you set up the DHCP server with the lease time as forever - each device should keep the same ip address.

then as SeaBass says use the IP filtering on p57 of the manual - that should do it

That router does more than I thought it would.

As the DHCP client list also provides the MAC addresses, I can simply determine the devices I want to block and then set up a 'deny' list in the MAC address control panel. No file sharing, no printing & no internet access is exactly what I want!

Thanks again guys
