Vista will not use manual default gateway

[Guest]

I work for a school and we have just received new computers loaded with
Vista. We are running a Win 2k3 servers, with DHCP. The DHCP address that
is given to all computers has a default gateway that is our content filter.
however on certain machines we bypass the filter and use our firewall as the
default gateway. The problem is that when I add the Default gateway of the
firewall to the TCP/IP settings I still cannot connect to the internet. It
seems that Vista is still using the Default gateway is given out via DHCP.
In the IP config the default gateway of the firewall is listed first. I just
set a static IP with the default gateway of the firewall and it works great..
So is there any idea why Vista is not using the manually entered gateway to
the firewall. thanks

What you can do is create a reservation in your DHCP server and the override
the default gateway for that reservation to the default gateway you want it
to be. no messing with configuration on th local mashine, DHCP does it for
you.
