Ok i pinged 4.2.2.1 and my gateway 84.50.44.1 from the cmd
4.2.2.1 pinged successfuly
But my Default Gateway didnt ping at all.
I might be guessing its my default gateway that is not allowing connection.

Can you please be more specific. Were you pinging from the Virtual machine, or from the XP machine?

Basically, I think it is a port forwarding problem. You need to forward the ports required by the server from your router to your virtual machine. Once this is done, your friend across the internet should be able to connect to your server.

I also read http://www.geekzone.co.nz/forums.asp?ForumId=66&TopicId=57920 assume it is the same issue.

BTW I can ping you 84.50.44.228
I cannot ping 84.50.44.128 as it is either not internet facing, firewalled, or is non routeable.

I assume your ISP gives you ONE static IP, and you need to use this to port forward to whatever servers you're running. Can you confirm the exact make and model of your modem/router.

I would love to change the world, but they won't give me the source code

So you are running your server as a virtual PC on Windows XP and have a modem only?

I think your problem is more than one...

First if you have a modem only then your PC will have the IP address your ISP gives to you. This is what happens on cable modem services for example.

If you need more than one PC at your home/office then you do need a router. You will configure that IP address on the router as WAN, and create an internal network for your own use - the LAN. This internal network will have your own IP addresses.

Software routers are not as easy to configure as a standard router if you don't know the basics.

Second the virtual machine itself. It should have its own LAN IP address. If you have the situation I described before then you can't just change the last three digits because that WAN IP address is assigned to you by your ISP, and they don't recognise that address as yours.

In this case you must use a router.

Just putting all that information in a single post so you understand it...

First when you have a Virtual Machine you will have a new IP address on your LAN. Because of that you will

Are you able to draw up a network diagram of what you're trying to achieve? As best as possible, with IP Addressing etc.

"And I have al lthe necessary ports forwarded." - What are the "necessary ports" and what IP Address are they forwarded to. Have you verified the port forwarding works?

This shouldn't really be very hard. The main issue as I can see is making sure the Modem/Router (your default gateway) is able to ping whatever address you've assigned to your virtual machine. freitasm has already covered this in his post above.

Audiophiles are such twits! They buy such pointless stuff: Gold plated cables, $2000 power cords. Idiots.

This stuff is getting too complicated on the modem. I think im gonna get me a router (like freitasm pointed out).
Luckyly i found one that works with virtual servers ( port forwarding) and supports Cable/DSL modems.
Life would be much easier.
But thank you all who tried to help me. I appreciate for the efforts you putted and all the painkillers you had to take cause of my bad english.
