cable router

[buschfsu]

I have a 4 port linksys cable router that i use with my 2000 network. My 2000 server requires a static IP adress so i used(196.168.1.3) one similar to that of the router 196.168.1.1.

I set the default gateway to the address of the router, and I can ping the router but can't get the internet content unless i dump the static ip and change back to "obtain ip automatically" on the server nic.

The WAN is set to obtain automatically from the ISP for the router, but that shouldn't make any difference. DHCP is off on the router because my server acts as a dhcp server and a dns server. (this is a home practice lab)

Any help is greatly appreciated.

sorry
server 192.168.1.3
router 192.168.1.1

A few different things could be happening. I have a similar domain setup at home with a netgear router. If you disable dhcp on the router and put in a static ip then everything within the origional dhcp scope (192.168.1.2-31, or whatever,) should nat. I think in the linksys router you can change the ips that nat in the web interface to the router. As well check your ip settings make sure you have the correct gateway ip which should be 192.168.1.1 and that you put the 2k dns server's ip in for you dns servers. If all that does work your router may be setup to spoof the mac address of you nic card and if dhcp is not setup on the router it cannot find your nic unless you specify the internal ip. You can change that setting on the router as well. You can also setup dns in 2k to forward all unresolved dns queries to the router ip, but that should not be necessary. You may want to make sure that there is an exclusion for the ip you are using on your 2k server. Try pinging the router and external ips to isolate where the fault lies.. so if you can ping the isp's router from inside with the static but you cannot ping

http://www.cnn.com

then its definitely a dns problem..

OK....

I can ping the router with my static server ip.. but i can't ping internet ip's (cnn.com) or pull them up with url's.


From your advise i should

set the Default gate way to the router ip 192.168.1.1
set the DNS to my server w/DNS running ip 192.168.1.3

as for changing the ip's that the linksys nat's, shouldn't it nat any address that it sees from the LAN? because the router is not giving out the addresses.

any advise is appreciated.
thanks

That router also can be set up as a dhcp server. If your 2000 server is also a dhcp and the service is turned on you could experience the problems you are talking about.

PROBLEM SOLVED

for all who guesses DNS you were right.

I had the DNS of the local server 192.168.1.3 listed on my server nic page instead of the DNS's provided by my IP. (It seemed logical at the time! Now as I think it through it makes sense)

Thanks to all who helped.

(linksys says you can run a DHCP server and the router DHCP as long as the scopes don't overlap. router = 192.168.1.100+)
