WOT: need computer help...., need to assign an IP address to a particular computer.... Options

[scottb]

on my network.

i have a linksys BEFSR41 and have 2 IP addresses through comcast (at least that is what they tell me).

i need to do the following:

find out my IP addresses

assign one of these addresses to my wifes work computer, and let the rest of the house use the other.


i have messed around within the router but as i don't know my ip addresses. i do an ipconfig and only get one ip address.

so any suggestions oh wise ones? my wife an i both work for the same company and the security system is such that only one log in per ip address is allowed (hence the need for 2).

hope this is clear enough....

thanks,

scott

Scott,

(1) I have to say that I am a bit confused about the term "gateway modem". What people generically call a "router" these days, will act as a gateway, will do NAT, will act as a firewall, will act as a switch.

(2) I think that your existing "router"s will do what they are asking if you configure them to use DHCP.

If you have a "switch" connected directly to your cable modem. Then you have two different routers connected to that switch. Both routers are configured to ask DHCP for an IP address (dynamic IP). If both are off, you turn the first one on. It sends out a DHCP request that makes it way to their network. The ISPs DHCP server checks and sees that you are allowed "two IPs" so it gives you one. You turn on the other router, it does the same thing. With the result of each router having a different IP. Yes, depending upon which one is turned on first, will determine who grabs the first one. But it really doesn't matter what value they get and in what order. The important thing is that you end up with two different public IP addresses.

If feel bad that you are still having problems with this. Have you considered having a local computer tech come out and work with you on this?
