sharing cable net

Postby gabriel_ameen » Sun Sep 11, 2005 7:40 am

Hi guys,
Right now I am using cable net. I asked my cable guy if i can share my connection with my other computers on the network. He says that I am not allowed to do so. I ask you if I do it, will my cable guys notice that and if he does then how can share my cable net connection with my other computers on the network and the cable guy not knowing it. Please I am looking foreward to your response. and let me tell you something my cable guy is a very rude and cruel person.

Dear gabriel_ameen,

If you have any p1 machine or any newer machine ,make it gateway .

Gateway Machine
Put two lan card in it ,one for cable net and one for your home network which plug into switch.

Buy one switch connect both pc's to your switch and also connect gateway machine to switch.

BTW you not define which OS, you using ?

Second solution,
As mahin said use NAT on current system and connect it to switch but you have to buy switch or hub in both condition's.

If you have any further query feel free to ask.

His real question

Postby omert » Tue Sep 13, 2005 2:01 am

I think what he is trying to say is that he don't wants its cable guy to know that he is using its cable connection with more than one pc.... I guess once the pc is on network any pc at all, if the cable guy or anyother admin who is good can find it out about the rest of the pcs unless someone is using firewall or something, but i am not sure. So may be some expert can elaborate the network system more...

Chances are your computer is connected to the cable modem thru usb and your ethernet card connects to your internal network.

first make sure you have bind installed from your distro's installation cd. (it normally enables a caching dns server.)

Download and install gShield a NAT/Firewall for linux

You will have to make a few minor changes in the gShield.conf file in /etc/firewall only to tell it which ethernet is your cable connection. gshield will enable NAT and firewall so you can share the connection with your network.

You will have to set your network machines' default gateway and dns to your cable connected computer's ip no.
