I have a desktop, 3 laptops, and a mobile. I want to able able to connect to one another with my Netgear WGR614. My desktop has internet via 3G, that I'd like to share with other nodes. I'm able to do this by connecting it to internet port of my router, but that prevents me from accessing laptops from my desktop (router stops me). Plz see http://img541.imageshack.us/img541/6497/i8i2.png
Here is one more setup I tried:
Connected all computers as clients to my router, and changed default route in all computers as my desktop's IP. This works but is too messy I need to change the configs time and again in laptops. Too frustrating to do them on mobile devices.
I use Ubuntu 12.04 on my desktop. Cleints include Windows XP, Ubuntu 12.04, Mac OS, and Android.
Please help me regarding this.
P.S. My 3G Internet connection is fastest I can get at this location (12-14 Mbps download and 5-6 Mbps upload). By the way what the pic shows is the case where we use all the laptops. We generally don't use all of them at a time and so it should be fine.
