Breaking MAC Addressing Binding Security...

Postby shakeel_jee7 » Tue Dec 18, 2007 4:35 am

Assalam-o-Alaikum

Dear Fellows!

Please I need your help in a problem.

I have cable Net connection in my home. The problem is that, they've done "MAC-Address binding" with the Interface card provided, now When I want to put cable in my second PC, I wont able to use the Internet. I just Browse the Network Shares fine, but Internet doesn't work then.

Please send me a solution to overcome this problem, I means, How to overcome MAC address binding or Forward the Packets received by that Interface to my other PC using another Lan card in the same PC.

I have the Following Scheme: Uderstand it for reference:

1. The PC in which I use internet has two LAN cards. In one card, the Cable Net is connected which is Binded, (MAC address and the IP), I want to do NATing or some other way to forward those packages to the Second LAN card in the same PC, so that card is connected to my Second PC, and hence, I can use the Internet on my second PC.

2. Note that I Different OS/Hardware in my Room, like Linux Box (Ubuntu 7.10 Gutsy Gibbon, RHEL 4.0) Windows (XP and Vista) and Apple Machintosh PowerMac G4 (Mac OS X and Mac OS 9.2 Classic), so tell me any Possible combination or configuration by which I use Internet on different PCs (Or Atleast 2 PCs)

3. Can NATing with iptables help me in this regard?

Please solve my this problem, I will be very thankful to you people!
Thanking you in Anticipation.
Allah ap ko Jaza-e-Khair de ga (InshaAllah)

AOA,

Dear Shakeel_jee7,

On the PC on which internet is working, simply enable IP_FORWARDING and Masquerade the outgoing interface.
