D-link 604 Broadband Router

I have a D-Link 604 Ethernet Broadband router that I wish to use in order to connect both my Windows XP pro and Linux Fedora Core 3 boxes to the internet. The Windows box connects just fine through the router, but the linux box does not. I have the linux box set up to obtain network connection info via DHCP from the router, which is what my windows box does. I have had this problem in the past, but I was able to connect to the internet by bypassing the router. I, therefore, know it is the router causing the problem. Is there any way to cofigure the router so it gets along with linux?

I have even tried turing off DHCP on the router and manually configuring the network settings for both computers. After that, the windows box still works, but the linux box still does not. When I tried to ping the windows box and the router from linux, it turned up a "host unreachable".

about host unreachable have you ckecked out the firewall rules in your pc?maybe some ports are closed and you linux box doesn't let ping.about manual configuration without dhcp is an easy part.edit the /etc/hosts like:
ip <hostname> <alias if u want> for both pc's (windows box and linux box).then setup iptables (man iptables for more).

Still not connecting :(

does the router has any firewall enabled?

Nope, it is wide open.

Check the cable from the linux box to the router make sure it isn't a crossover cable. Also give us the out put of ifconfig.
It doesn't sound like your linux box has a ip address.

su -
<password>
ifconfig

Make sure in /etc/resolv.conf
name servers are in there should look like
nameserver xxxx.xxxx.xxxx.xxxx <x= real IP from ISP>
nameserver xxxx.xxxx.xxxx.xxxx
Then check
/etc/sysconfig/network
should say
gateway = <what ever your gateway address is>

There is some more interesting stuff to look at in
/etc/sysconfig/network-scripts
ifcfig-eth0

Some stuff to look at.

In the past I have found the routers with DHCP don't always right to all of the right spots in Linux. Different distros write info in different spots.

Go to applications -> System Settings -> Security level, and see what the firewall/SELinux settings are.
