How can I direct Internet traffic only through a another gateway?

[BornAgainNoobie]

First of all, howdy folks!

I have several PCs on a domain that run windows XP with the following network configuration:

IP 10.x.x.x
SM 255.255.0.0
GW 10.14.40.254
DHCP 10.14.10.4
DNS 10.14.10.4

Normally for network usage i.e exchange, internet access(through a proxy), etc this config is fine. But what I would like to do is direct internet traffic only through a ADSL router (GW 10.14.40.253). The ADSL provider is with Bulldog and so two DNS addresses also have to be specified; 212.158.192.3 and 212.158.192.2. This setup would only apply to a few PCs.

I have tried adding the additional gateway and DNS addresses in the network settings. After which I get internet access though the ADSL router (after removing the proxy server setting) but then I can't access the exchange server through outlook, login to the domain can take 10-15mins, printers can't be accessed.

I have looked at adding routes to the route table but I can't see how you can specify what network traffic to route.

Any ideas?, your help is appreciated!!

You local clients will need to point at your internal DNS server otherwise your going to run into problems that you have said are already happening.

Is your local DNS server setup with forwarders with your ISP DNS IP addresses?

Are you trying to have some computers go through a proxy and the others not?

Im not sure what you are trying to do here.

If you want the PC's to go through the router then setup the DHCP, gateway to 10.14.40.254 and DNS to 10.14.10.4 your internal DNS server should forward any queries you need outside your network to your ISP DNS servers

Sorry the gateway address should have been 10.14.40.253, also just reading over it again if its just a few machines you require todo this to the you might be better setting static addresses to them.

Genius! Couldn't quite understand how assigning a static address to the PCs would do this but its worked and exactly what I needed. Thanks alot!
