How to create bridge - 3G Internet and Ethernet Port (LAN) on a PC ?
hi folks
here is my setup - I have a 4-port switch in the attic
I have a 3G internet dongle attached via USB to a PC lets call the PC "PC-net" the 3G internet dongle assigns itself as a gateway using a gateway IP address of 192.168.1.1 - on PC-net.
i went into the network conections option in windows 7 this is what i do
I create the bridge by highlighting the 3G dongle connection and PC-net’s ethernet connection together and right click and choose “create bridge” when the bridge is created I statically assign the bridge an IP address of 192.168.1.121 - so now PC-net has that address and when i connect the ethernet cable from PC-net into the 4-port switch i have 2 way flow (in/out) of internet through the ethernet ( lan ) port of PC-net
so that when connected to the switch via ethernet cable PC-net effectivelty shares its internet with all other PC’s connected to the switch - i can assign these other pcs static ip addresses - so theyre ok
preconditions - 1. i dont want to nor am i willing to buy a 3G router as i know its unnecessary and expensive
2. i want to be able to assign the client PCs their IP addresses manually in the range 192.168.1.125 to
192.168.1.128
how do I achieve this in linux (Fedora in my case) - if i install fedora (or other linux) on PC-net - how do i achieve the above windows equivalent setup on linux - can i do it using GUI or do I need to use those scary iptables commands ? thanks
