I want to simulate three computers, everyone behind a different NAT, in order to test hole punching.
I want a server that its address is know to the other two VMs, but the two VMs to be in separate NATs.
Any ideas on how to configure this in workstation 7 ?
Thanks :)
Honestly, if your three VMs are each under separate NATs and one VM has a public ipv4 address, then there is nothing specific you need to configure within workstation 7. You are ready to go to test hole punching.

Say I wish to have the interface eth0 to have a very low bandwidth. Is it possible?
As may be evident from the question, I am trying to simulate a network with varying bandwidths.
Note: I am using VirtualBox running Ubuntu to simulate the hosts.
There is a program in the Ubuntu repos that will throttle bandwidth on a process-by-process basis. It's called trickle. Here's another answer that deals with trickle. Hope that helps with your issue!

I'm having trouble with my network at work.
We have a LOT of computers on our network and one of them is causing me problems.
I'm rendering from 3ds Max via Backburner and I can see that there is a another manager distributing jobs.
I can see the IP adress of the computer (198.162.1.61), I just don't know where it is or what it's called.
Is there any way to get a specefic computers information if I only know its IP address?
Consult the ARP table. Then you'll get the MAC address, this you can match with the vendor via:
http://www.adminsub.net/mac-address-finder
command:
arp -a
use the following command to see the name of the computer:
nbtstat –a <ipaddress>
if you are lucky, you can also gather information via scans (ex program: autoscan, nmap, ...)

I have a college lan connection with static ip address and a Home internet connection(wired) with dynamic DHCP working. I need to frequently change the tcp/ip v4 settings in the properties of local area connection.
Is there a way I can have 2 network profiles for wired connections- one for college and one for home so that i can simply select which one to use.
Actually I want to be able to use this functionality to ultimately write a batch file that automatically detects my proxy settings and sets the system proxy settings, so that the browser settings also don't have to be changed everytime I switch the profiles. I was able to do it in ubuntu using a bash script. I want to do the same in windows.
Have you looked at the Alternate IP Address Configuration that is available in Windows

I want to connect ubuntu virtual boxes with each other on a network. I want to use hadoop on it. So i need to put them in a network. It requires ssh to communicate. Can anyone help regarding it.
The easiest way is to change your adapter to "Bridged networking" instead of "Nat", the default. This way the guest system will get an ip on your local network and you can connect directly to it.

Say i'm communicating with a computer A in a remote network .
Is it possible to know what are the hops that he is going through?
In other word, is it possible to detect what is computer A route to my computer?
I know that A might have a various routes to my computer , it just want to find a route. My whole problem begins with that fact that some networks "hides" there inside computer ( like NAT ) and just give you the gateway ip.
(I'm not talking about my route to his computer that can be easly achived by traceroute)
thanks!
The IP option Record Route asks routers along the way to include their address in the datagram so the route can be tracked. The trick is, many routers and firewalls are not keen on giving out this information and DROP packets with this option set. And, you'd have to get the remote peer to set the flag, so it would only be useful if you're in control of the software on the remote peer too.
