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

I am not as up on this as I used to be. I suspect that your ISP is giving you two dynamic IPs. I think what I would try would be to obtain a second router and a switch. Connect the switch to the cable modem. Plug the old and new router into the switch. Each router will now be able to get an IP via DHCP from your ISP. If you have static IP, then you need to setup each router with each IP on the WAN side.

On your LAN side you probably would need to continue to use NAT. Each LAN will be independent of each other and can't directly talk to each outer without routing out through each router. This means that you probably can't easily do things like share folders between your two PCs. You might be able to put in a second NIC in each machine and have them both on a shared network, but that is getting really complicated.

If the RSA security stuff doesn't like the NAT via your wifes router, then you could bypass the new router and have her plug directly into the switch that is connected to the cable modem. The problem here is that she will not have any firewall protection that the router would have provided. But I am guessing you can make this work as described above.

Someone with more experience than me, please validate this approach before he runs off and buys a second router and switch. (IMG:style_emoticons/default/biggrin.gif)
