NAT with 4 Real IPs

By maksumon ·
My office has decided to purchase 4 Real IPs to get dedicated bandwidth of 4 mbps. Now my question is will I be able to create a NAT with these 4 Real IPs to use with 20 users and will my USA office be able to remotely access those PCs using Real IPs including both way communication.

You need a very specific type of router

by robo_dev In reply to NAT with 4 Real IPs

Many 'load balancing' routers only have two WAN interfaces, and some have three. There are only one or two devices that have four WAN interfaces.

4 cables in - or 1?

by TobiF In reply to NAT with 4 Real IPs

Do you have 4 separate cables with 1 Mbps in each, or is it one connection with 4 public IP addresses attached?

Usually, for speed reasons, you don't need to have several ip addresses.

It could be good with at least 2 separate connections (via different ISP) for redundancy.

If you'd have several, say, mail servers in your network, then you could make use of several ip addresses. (This would in most cases not be an issue for web-servers, though, since they usually get the needed host name in the URL string)

There are 4 separate cables with 1 Mbps each.

insufficent information

by CG IT In reply to Separate Cables

what type of router are you using or plan to use to aggregate the 4 internet lines?

Even if you are able to aggregate the 4 lines, you still won't get a full 4mpbs bandwidth.

NAT you can configure one to one, many to one, or you can setup 4 seperate subnets, each for hosts that get to use only 1 line of 1 mbps.

Windows Server 2008 R2

by maksumon In reply to insufficent information

I'm actually planning to use a Windows Server 2008 R2 Server PC as One I've in my office with 5 NICs.

I want to know if I put 4 incoming real IPs in my Server PC, will be able to access my Office PCs from outside just using the Windows built-in Remote Desktop Application or not?

Ummm...I don't mean to be negative but....

by robo_dev In reply to Windows Server 2008 R2

To try to use a Windows server as a router with five WAN interfaces simply will not work.

First of all, you need a firewall of some sort, but that's the least of your problems.

Windows can do some simple routing, and some things it cannot do include: bandwidth aggregation, load sharing, and link-failover.

Assuming that your intent is to bind the five WAN interfaces into one, well...that just won't work.

What you need is a router that can support multiple WAN interfaces.

but then simply decided that the question wasn't worth the time, as I find most of the questions on Q&A.

personally, I think your wasting your time responding to questions like this.

and somehow I avoid making snarky comments, I don't know how.

come on, anyone with any experience in networking knows

how it works, how it doesn't work.

either you don't have any experience in it, thus don't know, which then begs the question, how did you get the job not knowing,which probably isn't the case...

Or you do, which is the case, and come up with senarios simply for the "joke".

Questions like these, simply make TR Q&A trivial and worthless.
