[-- Attachment #1 --] I assume that you are a FreeBSD user? if so you would "dhclient" to obtain a bootp or dhcp lease...but generaly speaking cable modems are layer 2 bridges, and in my experience they allow only one mac in a register...meaning you can only connect one NIC to the bridge...I have heard of people who where able to pay a premium for being able to lease more then one address...I'm not sure if this is correct or not...I would check with your cable company (it should be easy...after all you are an installer)...If indeed you are able to obtain only one lease (and you are a FreeBSD user) you can use NATD and a multihomed (two NICS)machine to share an internet connection among multiple computers (the info for NATD can be found in the freebsd handbook at www.freebsd.com/handbook I think) if you are using windows, you can use a program such as wingate (which is free for two users), or if your running W2K you can use ICS which I think uses NAT.

Our isp provider uses DHCP to gain a ip address. How do you configure this?.My company wants us to just configure one pc to gain access but I want to learn more about this topic. can it be done easily or at all?.
