NAT setup help

[Arun1]

Hi!
I have a Win7 64 based laptop at home and I'm trying to access an app on it from work.

The app is within a VM withtin my OS and I access it from the web browser of my OS(not from within the VM) using a private ip adress provided to me by the app, example,192.168.103.11.

What I want to do is set up NAT with the internal address as the one above, 192.168.103.11, the external adress would be my public ip given to me by my ISP, Reliance NetConeect+, I need to access the app from work by entering the public ip into the web browser at work.

How do I go about this?

You're gonna have to setup a one-to-one NAT. Your public IP from Reliance needs to be mapped to your private IP for the VM. I'm not sure which application on Win7 allows this. I would think that Kerio personal firewall and many other firewall softwares would do it.

It would be really simple using an external router. Set the router as a DHCP server for the 192.168.x.x network and set up the NAT-ting on the router itself. Your physical PC (in this case, your laptop) would also receive an IP from the 192.168.x.x range through DHCP. If you're just thinking of running this setup for testing then its ok, but for any production use, a separate hardware router is absolutely necessary coz of the performance.

Take a look in the VMWare settings also it if allows NAT-ting.

Let me get this right

You want the NAT, connected to your Home network to be assigned an ip address that is assigned by that VM app, and want to access that thing over internet?

A router will help, as boogeyman mentioned

One thing you can do is set up a virtual network connection in VM, disable the DHCP(of that virtual adapter), set the ip address to manual 192.168.xx(what you want), then connect the NAT to router, assign the NAT the ip address you set in the VM(through router)

For web access you can note down your external ip address, but if its dynamic, a DDNS service might prove useful
