Your IP Address should be a "private" IP address (like 192.168.0.2).
Private in the sense that the address is one that is reserved for
private internets as in RFC1918.
Your Gateway should be the private address you use on your network to
contact the router (like 192.168.0.1).
Your DNS server should also be the private address of the router.

(If the router's address is 192.168.x.y, then set your server to be
192.168.x.2).

You then have to run a DHCP service on your server.

I got quite exited by your reply. Unfortunately, the service (dhcpd) was not
running and I cannot induce it to either. I tried dhcpd from a terminal and
that told me that itcouldn't find dhcpd.conf. There was a sample file, the
contents of which are:

ddns-update-style none;
subnet 192.168.0.0 netmask 255.255.255.0 {
# default gateway
option routers 192.168.0.1;
option subnet-mask 255.255.255.0;

option domain-name "domain.org";

# Seting up an ip address is better here
option domain-name-servers ns.domain.org;
option nis-domain "domain.org";

range dynamic-bootp 192.168.0.128 192.168.0.254;
default-lease-time 21600;
max-lease-time 43200;

# we want the nameserver to appear at a fixed address
host ns {
next-server fixed.mandrakesoft.com;
hardware ethernet 12:34:56:78:AB:CD;
fixed-address 192.168.0.10;
}
}

I thought possibly that rerunning the network setup would re-write
dhcpd.conf but it didn't and I can only guess at what needs changing. If I
tell you that we make the first three octets in each of our LAN-side
addresses 192.168.23, should that be plugged into the conf file or is there
more to it than that?

Sorry to be such a pain.

Why would it be down? It should be on 24/7.

So put a switch behind the router and assign static addresses to all your
machines. If the router goes down, it doesn't affect your network.

Although I'd use the routers ip for dns, but it shouldn't matter. This
looks ok assuming all the ip's are correct. Is your routers address
actually 292.168.23.xx? If not that's your problem. The router is part of
the internal network and it's address should be the same base address as
all the machines in your network. IOW's if the router address is
192.168.0.1 (which many default to), then all your machine adresses
should be 192.168.0.<2-253>. I have a feeling you've assigned the wrong
IP to your server, not matching the routers base IP.

It is down when I turn am trying to get the damn thing to work properly like
it did up to Monday! From then I could receive and send emails and access
newsgroups but not the WWW. A a result I have had long spells with Linksys
tech support uploading new firmware and fiddling with the settings. That is
why I referred to it as 'down'

The 292 was a typo. It should have read 192.168.23.20. AS you can see from
other mailings, dhcpd on the file-server is stopped. It wouldn't start
because it couldn't see dhcpd.conf. When I checked there wan't one, jus a
sample. I have pasted its contents into another mailing on tgis thread.

Thanks for trying to help.

It's obviously a typo. I don't think anyone would consider 292 valid

292 is outside the range 0..255, so the IP address you have there is
not valid. Did you mean 192 (which would mean that the address is one
from the RFC1918 allocations)?

Sorted, thanks to you. I edited dhcpd.conf and saved it. I had to run the
system down and reboot for unconnected reasons. By this time I had Googled
for details of dhcpd.conf. When I next looked at /etc in order to improve
my editing, I found two files dhcpd.conf and dhcp.conf. They were very
similar so I edited both of them. When I restarted dhcpd everything worked!
Thanks again.
