Network Change

Hi all. This is my first post, so forgive me if I screw it up. I have VaporSec set up and working great. Problem is when I leave my LAN at the home office (192.168.2.0/24) and go to my office environment which is network 192.168.1.0/24. The remote IPSec device is a Watchguard V10 and is set to only allow the 192.168.2.0/24 remote network access as the local network on the other side of the watchgaurd is 192.168.1.0/24. I don't want to make any changes to the Watchguard ned. Make sense? ( Hope so.. ) I was thinking that using the Local IP in Vapor Sec would be the way to do this but no go. Am I doing something wrong? missing something? or just way out in left field? Any help would be greatly appreciated... B.
