Changing subnets on a Home LAN

I use XP (SP3 MCE) and have a home LAN using a Linksys BEFSR41 router with 4
wired ports fed by a cable modem. I also work from home and have software
installed on my desktop to use a VPN in conjunction with my work. Every day
I have a bat file run (through scheduled tasks) to copy my data to my wife's
computer and her data to my desktop (for backup purposes). All of this
copying is, of course, done over the LAN. Unfortunately, I have to
disconnect my VPN to do so, because the computers cannot see each other over
the LAN whenever my desktop has the VPN running. Fortunately, my VPN
(Cisco) has a feature that can be checked to "allow local LAN access", which
I have now checked. But the computers still cannot see each other. I have
found out that the reason is that I need to "set up my LAN so that my
machine's IP address is one of 3 subnets listed below.
192.168.214.0/24 192.168.215.0/24 192.168.216.0/24 "

I need your help in doing this. I have several questions.

1. Do I change these things on my router or in Win XP?

2. I think it is in Win XP. If so, is it in the dialog box for Network
Connections/properties/Internet Protocol (TCP/IP)/Properties?

3. If the answer to #2 was "Yes", do I do this for my normal "Local Area
Connection" or for the one connected to my VPN? The normal Local Area
Connection has selected (in that dialog box) "Obtain an IP address
automatically" and "Obtain DNS server address automatically". But the Local
Area Connection for the VPN has specific IP addresses for IP address, subnet
mask, default gateway, preferred DNS server, and Alternate DNS server.

Can anyone give me guidance here?

Thanks in advance.

Bob
