You will have to get a pool (instead of 1 address and doing the NAT stuff) of WAN IP addresses from your ISP. Notice this might increase your internet line subscription cost.

Question
LAN - Public and Private adress How?
Hi!
I have an question about Public and Private ip adresses.
I have a Lan With 20 computers they all have private ip adresses and they go trouh a firewall (ip cop) and a Server who holds GPO and is a domain controller.
Now all clients have privates ip adress but one public ip adress to internet, they share internet connection. But some times the clients need to connect to a server that only accepts 1 ip adress, how do i configure sow it´s look like it comes from diffrent ip adresses istead off only one? is this possible on a LAN or tho the clients need to have diffrent ip adress to connect to this server?
HELP!

That's the way I've done everytime that i found this problem. On a IRC server you usually can log twice with one IP (one clone allowed) but this is up to the IRC Admin.
Contacting him is the best answer that I can give you (besides going into maybe some ilegal stuff like spoffing the IPs and things like this).
Waiting your feedback.

"That's the way it's done on the IRC servers for example, because it is allowed only one conection per IP and server."
Can you please explain to me how it works with the IRC servers and how they do for accepting more then one connection from a ex private adress.
I dont follow... i still have 1 public adress, how do they configure sow that i can connect from various private adress connect to the server buy just using i public adress than only allow one adress. Do i have to configure something to or just they have to?
Hi Morriz,
Sorry, maybe I've done a muddle with this. You can't do anything except asking to the IRC Admin to allow 'n' connections to his server from your public IP because you have a shared internet connection. He will then configure the IRC server to allow this. It's just a rule of the IRC server.
Feel free to askme again if still you don't catch it.
See you.
SoMoS
Yes, there is a way to put more than one IP to a NIC. But take in mind that public IPs cost money. If you want to fix the problem like this just ask me and then I will show you the way to set up the thing.
Also you will get only one user for each IP. I donno if it's the best solution possible but this is up to you, of course.
See you.

Hi Somos!
You really know your stuff! (good)
Can you please help me and guide me how to set up my lan clients thats are in private ip adress to more public ip adress. Ihave 4 public ip adress that i whant to assign to 4 clients that are in an private adress, how do i do it?
My Lan:
ISP -> Firewall -> Server With GPO, AD, DC (has private adress, but isp dns and with firewalls Gateway) -> 20 clients that has private adress from 192.168.0.3 -23 and has Servers dns adress (192.168.0.2) to connect to internet. Gateway for the clients are ther firewalls(192.168.0.1)
Now how do i configure 4 clients on lan to connect with publics ip adress and still stand behind firewall and the server?
You may want to look into using an IRC proxy the applications are out there and would allow you to use differant proxies for differant machines. it would allow your machines to technicaly come from differant addresses because they would be routed through the proxies. and there are many free programs and free proxies out there if you look for them. it's a solution in any case.
Herro Morriz, different timezones so sorry for the delay,
as daveteh said, it is the firewall that must assign the IPs (it is the onlt machi on you LAN that manages public adress isn't it?). So please, give us the model of the firewall to look how to manage this. There is one different way for each f*·% firewall on the market (when they can do this, not all firewalls can manage this, of course).
See you soon.
SoMoS
Yeah, maybe this work, but your users are going to be clones I think. When a IRC server sees two users with the same IP it thinks that there are clones and the number of clones use to be limited to 2. You can try if you want.
This is a good IRC proxy:

Windows - http://www.antifirewall.co
Tell me how they work with you. Maybe I can help you further.
Waiting your feedback.

No comment has been added to this question in more than 21 days, so it is now classified as abandoned.
I will leave the following recommendation for this question in the Cleanup topic area:
Split: daveteh {http:#9320196} & SoMoS {http:#9329110}
Any objections should be posted here in the next 4 days. After that time, the question will be closed.

Hello Morriz,
If what you have is a server that only lets you to connect from one IP at the same time and you are having trouble because all the Pcs on your LAN have the same public IP and then they can't connect simultaneosly to this server, I'm sorry to tell you that you can't do nothing at all. You have only one internet (public) IP and thats all. The fact for the server is that there is only one machine.
On the other hand I don't know which kind of server allows only one connection for IP but it's pretty sure that if you talk to the admin of the server you should get the permission to log to the server with more than one IP. That's the way it's done on the IRC servers for example, because it is allowed only one conection per IP and server.
Maybe you can explain me more about the server and I can help you more.
Waiting your feedback.
