Eric, You are correct... Sorry if I didn't clarify this earler. I have my main PC (which has the PCI NIC that has the MAC address the cable modem wants to see) then I have a different PC which I want to use as a router/firewall (on a 486 using FreeBSD setup with NAT and IPFW). I had an old 486 laying around that I haven't used in years and thought it would be an good use of equipment since FreeBSD runs like a champ on it. I wanted to see if there was a software solution because the ISP pretty much told me NO when I told them what I wanted to do. If I was to talk them into changing MAC addresses, there is no guarentee that my config the the FreeBSD box would work, since I'm kinda new to setting up NAT on it. Then I'd have to call them back to change it back and it would turn into a big hassle =). On another note, I was able to change the MAC address using ifconfig. The command line I used was: ifconfig ep0 lladdr 01:02:03:04:05:06. Now all I need is to find out how I can get it to poll the DHCP server again for a new address. In NT it's ipconfig /renew, but not sure about *nix. Thanks for all you guys help =) Brett >From: Eric Six <erics@sirsi.com> >To: "'barbish@a1poweruser.com'" <barbish@a1poweruser.com>, Eric Six ><erics@sirsi.com>, Brett Cates <bcates513@hotmail.com> >CC: FBSDQ <questions@FreeBSD.ORG> >Subject: RE: Changing MAC Address >Date: Mon, 8 Jul 2002 14:11:51 -0500 > > > > >money for multiple PC's using the Internet. =P I can't switch NIC's >because > >they are different bus types (The NIC is PCI but my router is a 486 w/ >ISA > >only).
