two ip ranges

[hashashin]

I have a windows 2000 server that assigns ip address to the 15 clients. The range is 192.168.1.2 <-server 192.168.1.30

I have a Windows xp Pro client in the network with Two nic's one for the Lan and one for the cable broadband, the
broadband routers ip is 192.168.0.1 and this is where my problem starts arrrrrgh
the xp pro pc has no problem connecting to the internet it gets an ip from the isp.

I'am unable to ping the router from the 2k server or any of the clients. When i change the routers ip to 192.168.1.1 I can then ping the router but I have no access to the internet.
If any of this makes any sence to you please help I'am at my WITS END.

Thankyou Joe.

I wish you posted the result of ipconfig /all here so that we have more details. Assuming xp is ICS host with internal IP 192.168.0.1, all client should be in the same subnet 192.168.0.x. If, for some reasons, you need two subntes, you may add one more router to connect these two subnets.

Thanks for your replay ChicagoTechNet,

win2k server is dhcp it's range is 192.168.1.2 - 192.168.1.30
subnet 255.255.255.0

i have reserverd the xp pro pc to have the ip address of 192.168.1.17 for the lan the second nic in the xp pc get it ip address from the netgear dhcp hub's range is 192.168.0.1.
I'am not using ics in anyway i just to get access to the internet and I think it's has somthing to do with the w2k server.
I'am off site at the moment so i can't give you the ipconfig /all

i think your problem is ICS on the XP m/c ( put the two NICs in the server and set up RRAS)

ICS installs a type of DHCP and DNS server and two dhcps on the same network is BAD your clients wont know what gateway they are s`posed to use .

I would suggest not using ICS and go get yourself a cheap cable router instead and use that. Have all the computers on the same subnet i dont see a reason why you have 2 subnets here apart from that the default ICS subnet is different from the current one you are using.

Thanks for the replay Guys

I dont have two subnets I have two ip ranges, and i'am not using ics, I'am just trying to access the lan ip of the netgear router i cant access it if the ip range is 192.168.0.1 if i change it to the lans range if 192.168.1.1 i can then ping it but i'am unable to get internet access through it.

Sounds like you have no gateway or dns ips supplied to the clients or the router isnt routing the traffic for that subnet. You have 2 class C subnets 192.168.1.* + 192.168.0.* if you have both of these on your network you will need to route between them.

 

[hashashin]

yeah FaiTHLeSS I think your on the right track there mate
any idea on how to test or impliment you idea, I'am not the sharpest tool in the shed...


Cheers Joe.

If you have a router why cant you just plug it into your switch/hub instead of into your XP box? Most routers let you change the IP range it uses to. You really want to just create the 1 subnet easiet way would be to change the IP range the router used to 192.168.1.* range.

Your network would look like this:

Router --> Hub/switch -> computers.

Next decide what you are going to use to lease the IP's to your clients? I suggest you use your Windows 2000 server, in the extra scope options lease the gateway and DNS servers addresses to.

Run a local DNS server for your network and have all cleints pointing to that server for DNS. Within the DNS settings setup forwarders to point to your ISP's DNS servers.

Disable any other DHCP servers that might be on your network.

Reconfigure your router to the new IP range it should allow you todo this.

Test your new configuration.

Your router should also have some sort of firewall on it to make sure that is enabled.

If you have some more question please can you post what hardware you have so we are able to help you more, ie. router/switch/hub ? It gets confusing trying to work out what you have some of the things dont add up.

Hope this helps

Faithless is correct. Get yourself an inexpensive router and let it take care of it. My setup is a simple cable modem -> Wireless router-> My machines connect via wireless nics. Router supplies IP addresses, don't need to get fancy. This setup will handle up to 250 + clients, and almost configure themselves. Unless you are trying to set up a network for the sake of learning or testing, keep it simple and avoid gray hairs. I'm using SMC, but there are many kinds you can use. Good luck.
