IP address ranges for VPN and normal LAN use with notebook

Hi all!

As far as I can see from other posts, in order to use VPN between home and office, I have to setup two different IP address ranges, e.g.: Office IP range: 192.168.0.xxx Home IP range: 192.168.1.xxx

But now I have to use my WinXP notebook in both LANs. If I set its IP to lets say 192.168.1.15 it will work fine at home and it will connect fine from home through VPN to my office network. But what will happen if I work in my office? My notebook's IP address will be outside the allowed range.

Please let me know if you can think of a solution to my problem.

Thanks a lot! Anguel
