Static Routing Or NAT ?

By colin.mac ·
The product I use is the Buffalo wireless Air Station WLAR-L11-L(with its own WAN static IP address, sub net 255.255.255.24 and I have three systems using the USB network adapters and four systems using PCMCIA card network adapters.

I am tryingto run one of the systems with the USB network adapters(Win 2K O.S.) as a web site host with a static IP address which was supplied by our ISP, i've manually assigned this system with the static IP address and I've set up the DNS which was supplied by our service provider. I'm able to see and access other systems on the network with this manually assigned system but am un-able to connect to the internet or PING any other system on the network(strange I know !)

I've disabled DHCP and assigned each of my other systems in the range 192.168.0.3 upwards and they can all access the internet.

I have a BT ADSL modem which has it's own unique gateway IP address set up.

The systems which I assign static IPs in the range 192.168.0.3 and upwards
can all access the internet as long as i set the default gateway to
192.168.0.1. But if i try to set up a system with the static IP address which was assigned by our ISP I cannot
access the internet or the air stations setting screen but I can access other PCs on the
network.

I've been advised that I may need to set up NAT or my own static routing but both these subjects are rather new to me so if anyone has any heplful tips or can see an answer to my problem it would be greatly appreciated.

Thanks in advance.

Static Routing Or NAT ?

Well your doing nat with the gateway now.

Your private 192.168.0.x addresses are translated to a public address etc.

Now you want to go the other way. I would doubt that this device will allow you much in the way of config.

You could do itthis way;
You will need a additional public IP from your ISP.
Get a aditional hub (is this cable or DSL).
The new hub will work as a DMZ. The server and the WAP will sit on this segment. The server will have a public address, and the WAP will have a public address.
Internal clients as well as external clients will access the server through the public address.

More info? Ask.

I would then suggest puting a public address on the server, configuring the DMZ.

You can use NAT to direct inbound traffic to a single internal address, but that brings other issues with it.

The buffalo air station does allow me the option of setting up a DMZ, IP Masquerading, Routing, NAT etc... and can hold up to 250 nodes.

I've got 5 static IP's from my service provider, only one is been used at the moment and is set as the WAN address on my air station.

My connection is ADSL. Is there some way I could create a sub network of static IP's assigned by my ISP within the existing network and route everything to that area separately from the private LAN ?

If i did get another Hub, what compatibility issues would i need to worry about ?
