Hi, Is it possible to substitute MAC address of all networked devices (2nd PC, Mac and IP Phone) connected through 2-interface shorewall, so all traffic will be seen outside as coming from the MAC of the external network card of my firewall machine? The problem is that I have cable connection at my home to my ISP, and they somehow managed to deny traffic coming from any PC except firewall, I think they do MAC address checking. Of course, I can use squid, but hardware IP Phone do not work with it. ********************************************* * Best Regards --- Andrei Verovski * * Personal Home Page * http://snow.prohosting.com/guru4mac/ * Mac, Linux, DTP, Development, IT WEB Site *********************************************
