Routers and IP Addresses

[speedchick]

Probably a stupid question but, I have a laptop, my other half has a pc and a laptop and at present they are all connected wirelessly to each other through a Netgear router.

The kids are getting a laptop each for Christmas, and we have already done all the install and stuff and connected them to the 'home' network.

We are on NTL, and of course there is an IP with that, and at present we are running the pooters on ip numbers ranging from 2 to 7 (each machine keeps finding its own)

Anyway, we want the kids' lappys to work with the home network but not access the internet. We did block one of the ip addresses at the router and when my other half turned his laptop on this morning it picked for itself the blocked ip and so wouldn't connect to the internet.

Is there anyway we can make each ip stick to the relevant pooter so that we have the same three internet enabled and the two kids ones not internet enabled?

(I do hope all that made sense, I think I am asking if we can get each pooter to assign it self a static ip, can't you tell I dunno what I am talking about )

The 'right' way to do it is to create a reservation on the router, so everything still finds its own IP but that particular machine allways gets the IP thats reserved for it. The practicalities of how to achive this depends on what make & model of router you've got though, If you post it someone might know.

Good luck with this - I am having a nightmare trying to do the same thing.
Got a Netgear DG834PN and each machine always has it's own IP.

I am trying to restrict access to the internet for one of them between certain hours. Thought I'd sussed by setting up a firewall rule that blocks all outbound traffic between certain hours, then assigning an LAN and WAN IP address to the rule.

Don't work though

If you figure it can you post here?

You could hard code al lthe IP Addresses on each machine and not specify a gateway or DNS Servers on the kid's Computers

e.g. Router IP 192.168.0.1

COMP 1 - For Adult
IP 192.168.0.2
Subnet MAsk 255.255.255.0
Gateway: 192.168.0.1 (The address of the router)
DNS1: What ever you ISP uses
DNS2: What ever you ISP uses

COMP 2 - For Adult
IP 192.168.0.3
Subnet MAsk 255.255.255.0
Gateway: 192.168.0.1 (The address of the router)
DNS1: What ever you ISP uses
DNS2: What ever you ISP uses

COMP 3 - For Kids
IP 192.168.0.4
Subnet MAsk 255.255.255.0
Gateway: 0.0.0.0 - (See no router = no Internet)
DNS1: 0.0.0.0
DNS2: 0.0.0.0

COMP 4 - For Kids
IP 192.168.0.5
Subnet MAsk 255.255.255.0
Gateway: 0.0.0.0 - (See no router = no Internet)
DNS1: 0.0.0.0
DNS2: 0.0.0.0

This will stop them accessing the Internet for sure.

You'll probably need to adjust the number s a bit to fit your network.

Key thing is to not let their computer get it's IP/Gateway/DNS settings using DHCP.

HTH.

What about using the desktop as the internet gateway? The other computers can be networked with or without internet access.

I'm a bit fik wiv computers but that would work wouldn't it?

I'd second sneakyneil's advice. My previous router was a Netgear and it was dead easy to set up reservations. Reserve an IP address for the MAC address of each of the machines you don't want to access the Internet, and then configure the Firewall on the router so those IP addresses don't get through.

If you do a quick google for the model of your router and include the word 'reservation' in the search, someone somewhere is bound to have documented the process - it's really pretty straightforward.

I wouldn't assign a static IP to each machine if you can avoid it.

edited because 'model of your number' didn't really make sense.

Thanks guys, am passing the info on to him what thinks he should be obeyed, given my recent record with pooters, it's infinately safer to let him play

[jimmyjimjim]

As above.
Set it up so that particular MAC addresses are assigned to particular IP addresses, then do what you want to the IP address.

Depends on what router you have, but i whould just go into my router settings and change when certain computers can access the internet, and set the kids ones to never!
