Re: Voange WRT54GP2 router to Fedora Core 5 - eth0 won't get IP address and won't start

What I want to do now is have all 3 of my computers plugged into the
Linksys and allow them to setup themselves with automatic settings for the
Windows machines and configure my Fedora box to connect with DHCP to get an
IP address and DNS server addresses. Then I can setup the router to forward
the server ports or if I can find it, put the Linux box in the DMZ,
although I cannot really find that setup in the browser admin screen.

Page 41 of the user guide - Applications and Gaming - DMZ
seems to have what you need.


Anyway, the issue is that the Fedora box will not connect to this routher.
When I boot, eth0 failed to get an IP address and thus in disabled. The
computer is not online anymore since connecting the Linksys router in
between the cable modem and the Fedora Box. It just does not work. I can
even try "service network restart" and "Determining IP information for
eth0" times out and fails. The Windows XP machines have no problem at all
with connecting to the Linksys, they boot fine and work great on the
Internet.

One thing that I have noticed is that I have always used 192.168.0.xxx for
my home LAN NAT addresses. The Linux box used 192.168.0.1 as it's local
address and the other machines on the LAN fall into that range. The Linksys
router on the other hand, dishes out IP addresses in the 192.168.15.xxx
range, starting at 192.168.15.100 and is set to go to 192.168.15.50.

I suspect a typo here - 100 to 250 maybe?


What is the problem here and what do I have to do in order to get my Fedora
Core 5 server to get an IP address from the linksys? This really bites, I
desperatly need to get this Linux box back online and am stumped, why won't
it get an IP address from the router?

I don't know Fedora. Do you have any of the IP setup fields defined,
e.g. do you still have a netmask or a gateway defined? That might
interfere with DHCP.

However if you want to use the DMZ facility the manual says you need
to use a static address, so I would do that. Just make sure it is
outside the DHCP range.

With DMZ your server has an address which is in your LAN range, and
the router forwards requests to it. Those requests come in on the
router's IP address. The issue here is that you need a static address
on the WAN side of the router - or use dyndns.org. The remote clients
need a way to find your router.


I would really like, in the end, to connect my setup as such:

Cable to modem
Modem to Vonage router, Linksys WRT54GP2
Linksys to Fedora Box on eth0
Fedora to hub on eth1
hub to other computers on the LAN

Fedora - static on Eth0 and DMZ configured. Run a DHCP server on
Fedora, supplying addresses on Eth1. Since you are using DMZ, the
Linksys firewall will not be protecting you very much, so you will
need the fedora to act as firewall for the rest of your network.

You'll need to route on Fedora, so you need to use two private network
ranges. I suggest 192.168.15.x for the linksys-fedora link, and
10.0.0.x for the LAN


I would prefer this because I could transfer large files, like a DVD or CD
image file and with all the computers connected via the 3com hub 8/TP100
because that sucker was fast. I could transfer a 1Gb file in less than a
minute, with the network connecting the computers using the LInksys, I
would have to wait almost an hour to transfer a file.

This puzzles me a bit. Your existing switch seems to be transferring
at about 150MBit/sec - assuming it is 10/100 that is very good going.
The Linksys is also 10/100, so the only thing I could see slowing it
up is the firewall function - and that should be configured so it
doesn't affect lan-lan traffic.


Somebody please help, how can I get my Fedora box to boot up and get
connected to a Linksys router?

Thank you and Happy New Year.

Best wishes, and good luck.
