you can use NATD to fix this but you will need to have "mapped" name for 
all teh machines on the
other nets..

e,g on net 1 you will see the other net as being 192.168.128.x
and on the other net you will see the first net as 192.168.128.x (or 
whatever you want)

I have done it once but you will need to read the natd and libalias docs
as it has been a long time since I did it.
I also had a DNS spoofer that translated DNS requests between the two 
nets as needed.
but That is long gone. (I have another one now but it is proprietary).
