I suck at networks.

To be able to play Quake over the Internet from more than one machine
I have to assign a static ip address.

When I have trouble with connecting to the Internet and have to call
my ISP they always make me connect to one machine.

I can never get the thing working again.

Right now I have one computer plugged directly into the modem and it
works. I had to change the computer to obtain an ip address and the
dns address automatically in the TCP/IP properties.

I can't get it working when I try to change it back.

The settings I want to use are

192.168.001.110
255.255.255.0
192.168.001.001

The preferred servers are the ones that tech support gave me. He also
said that I could do an ipconfig/all to get the numbers. I checked
and they are the same as the ones he gave me.

066.190.172.252
068.191.247.254

The tech support guy said I should be able to assign the IP address
and leave the DNS settings to automatic, but when I assign an IP the
DNS settings for automatic are grayed.

What am I doing wrong? I sometimes think that I don't give the
computer enough time to "reset" using the numbers but I have waited a
couple of minutes and it still won't connect to the Internet. I can
talk to the other computers.
 
Hi
Hi
I assume that have a Router and local Network.
If while connecting to the modem Quake works and it does not work behind the
Router, then you probably did not open Quake related ports in the Router
(ports 28004 and port 28005), look in the Router's manual for how-to.
As for few computers playing at the same time.
Local network assigns IPs from the Router's DHCP, and that has nothing to do
with the ISP's DNS.
I do not know how Quake works but some Game Servers do not allow more than
one computer on the same Internet IP.
No matter how many computer works on your Network they are all using the
same Internet IP number.
In addition, even if you can use more than one computer on the same IP you
need to change the ports on the second computer since ports ports 28004 and
port 28005 can be directed only toward one computer.

Well, that's OK. I'm a lousy dry cleaner, and you should probably not drive
a car whose transmission has been overhauled by me.

Really? I am not a gamer, but this sounds odd to me. Anyway - do you have a
router/firewall? If so, what kind?

What exactly does that mean? (oh, and how often do you have problems
connecting to the internet?)

How did you try? Did you try the "Alternate configuration" tab? I have never
managed to get that to work right, but some have. IF not, you just need to
re-enter the information. Now, if you were using a router/firewall between
your computer & the modem, the issue may not be with your computer at all.
Try pinging the router's LAN IP (default gateway) to see if you can get to
*it*. If so, it's probably that the cable/DSL modem isn't giving an IP
address to the WAN interface on the router. Unplug or turn off the modem,
and do the same on the router. Wait 15-30 seconds. Turn on the modem - wait
15-30 seconds. Turn on the router.....wait until it fully boots up & you can
ping it by LAN IP. Then try getting out to the internet again.

That's correct - he was mistaken. Now, the *reverse* works fine - you can
use a dynamic IP with a static DNS server IP. However, that doesn't help
you.

I'm not sure I fully understand your config -

What I'd suggest you do is use a decent firewall gateway/router appliance
that does NAT, DHCP, and supports DHCP reservations based on MAC address.

You can set up a DHCP reservation for each of your computers, so that they
always get the same address when they ask the DHCP server for one.

You can set up whatever rules you need to in the firewall (port forwarding).

If you ever need to unplug your computer & connect it to another network, it
will get an IP address there. When you reconnect to your LAN, you can do an
ipconfig /release ipconfig /renew, and it should get the IP address you set
up as a reservation.

Without knowing more information about your setup, I'm not sure I can help
with the specific problem you're having, but the above should help you avoid
it. Hope this made at least some sense to you!

Update.

I think the root cause of my problem was that my ISP (Charter) changed
its DNS servers.

One thing that puzzles me is that even after I changed things back to
automatic I could not access the Internet.

My router was reporting nothing for an ip address.

I called my router tech support (Linksys) and they instructed me to
reset my mac address to get everything working again.


Thanks everyone for you suggestions.
