How can I set it up on y router, so that it gives the DNS settings to each client computer.

So that rather than it giving each computer some random DNS (I cant remember what it actually gives them) and me having to manually put in the primary as the server and the secondary as the router.

It will automatically give the clients the Server as the primary and the secondary as the router.

This is a great help as it saves you hacing to change the DNS settings whenever you connect to a differant wireless network.

I have looked right through the router configuration (havnt yet gone to the documentation) and I cant seem to see anything, there is the range that it gives out the IP's but not what DNS settings it gives to each client.

The way you have explained it seems confusing.

You either set DNS up in your router, and it gets served out via DHCP (or via static addressing).

Have you entered any DNS settings into your router?

What server do you have that you are referring to?

Under basic settings you can tell the router to use the ISP automatic DNS addresses that will be negotiated and supplied during PPPoA authentication, or you can set "Use these DNS Servers" and supply your own, eitherway during DHCP negotiation with the router and your PCs the router will offer its own address as the DNS server and use the ones detailed above to resolve addresses.

The simplist way is to leave the DHCP action to put the router as the DNS server, then the router will sort it out, either using the addresses offered by ISP authentication or ones you manually override.

If you set your PCs not to use DHCP and setup static IPs for them then use the gateway (which is the modem/router) as the DNS server.

To save having to manually put the DNS settings into each computer. I want the Router (our DHCP server) to give each client the Servers (SBS 03) ip as the Primary DNS and the Router as the secondary DNS.

The use of having the Server as the primary DNS speeds up the logon, and when I forget to change DNS settings back when I hae been connected to other networks it becomes a pain.

So for the router to automatically give those settings makes it alot better.

Does that make a bit more sense?

Under Basic settings there is the DNS settings, but that would be for getting the DNS settings from Xnet wouldnt it (xnet is our isp)

If you have all your PCs set as DHCP then that act will give your PCs DNS address of the gateway. Thus whatever your modem(gateway) is set to (ie what your ISP gives on PPPoA or what your manually set them to). I dont understand your problem.

A DSL modem as you have will get its DNS addresses from your ISP, it will tell all DHCP clients to use the gateway address as the DNS address, which is fine, because it will get the right end result.

Think about it, a NAT router will do one of two things, if you tell your PCs an explicit DNS address, then for every address request the PC will ask the gateway (it has to) to pass the DNS request to whatever DNS address it has in its database. Or the PC can use the gateway (router) address as the DNS address, in which case the router will use whatever DNS address the ISP has offered the router.

The end result is the same regardless.

I want the DHCP Server (The Router) to give the computers a differant DNS though, rather than giving hem Xnets DNS settings, I want it to give the computers a primary dns of 192.168.0.3 (server) and 192.168.0.1 (router) as its secondary.

Oh ok, thats a little different, you will have to do that manually on each PC, I dont think you can override the modems DHCP action, it will always tell the DHCP clients to use its (modem/gateway) address for DNS, the router then using the external addresses supplied by the ISP authentication or manually stated. I dont think I have ever seen a NAT router that allows what you want, you would be better off setting up PCs with static IPs and then you can control DNS server addresses.

ok, I was hoping that somthing could be done  but obviously not. It gets a bit of a pain when people take laptops out of the house and connect them to other wireless networks and have to change there settings, and then when it doesnt work I end up getting a phone call. and then when they come home they have no idea of what there settings are.
