Network setup help 1

[ronnj]

This is a problem and I need some help new to networking.

I have 30 computers on a network 3 of which are file servers, they are presently configured as all static ip's and are working fine accessing the internet and the 3 file servers,

Now the new wrinkle our current ISP can not deliver any more speed to us due to problems that they can not figure out.

We went out and got a second dsl line from another provider with just 1 static ip addy.

we have 1 application that requires our machines to maintain the same ip address to function. we asked provider for additional static ip's and were told there are no more available at this time for the east coast (verizon)

how can i set up to assign all machines thier own ip address and access servers and internet

thank you very much for your help

Why not just set up one of your existing servers as Proxy server? Or even an old pc and stick linux on it?

Could you not use DHCP/NAT?

You could give all the machines in the network their own internal address, eg. 192.168.x.x, this would work only on your own network, so you can make them static - you don't need every machine to have its own unique static IP address for them to use the internet...

You will then enter the gateway address (thats the computer they go through to get onto the internet), which may be one of your file servers, as the "default gateway"

When it goes to the gateway machine it will be routed out as normal, and each machine will still be able to have a static address INTERNALLY and therefore won't affect the use of the program that requires static addressing, and won't require you having to pay for more "internet ready" static IP's

Is this what you mean?

Iain - I'm not sure how "getting an old pc and sticking Linux on it" would solve this problem??

Well that is why NAT was made.

Just to clear things up a bit for you....

Nobody ever thought that the internet would take off like it did. Current IP addresses are 32bit, which gives a THEROETICAL maximum off 2 to the power of 32 addreses. (Thats a hell of a lot). But,IP address classes, and internal (Private)IP's (192.168.x.x for example) and other factors significantly reduced this figure. IP addresses were getting used up too fast, so along came Cisco with their Network Address Translastion protocol (NAT).

This greatly helped matters, as an entire network can run off just ONE external IP address, and all machines on the inside of the network can be configured with private addresses, and let NAT do all the work. Otherwise there would not be enough addresses to go round

Sorry, I meant get an old PC chuck a free piece of software on it and run it as a Proxy server. Sorry for the confusion.
