No, we do not know about the gateway.  However, recall from the OP that 
"eth1 is set to DHCP and is part of 192.168.0.0/24", which means that 
the route back to the 192.168.1.0/24 network could change as the 
""router in question reboots.  So, either the routers are running some 
sort of routing protocol, or the 192.168.1.0/24 network needs to be 
""hidden from the 192.168.0.0/24 network.  This is very easily 
accomplished with SNAT / MASQUERADE.

Something to keep in mind is that the source IP is a dynamic IP on the 
192.168.0.0/24 network, so it would be better if MASQUERADE was used 
verses SNAT.  SNAT does not clear out stale nat translations like 
MASQUERADE does when the IP for the interface changes.
