Remap local addresses, to connect two networks with an overlap in the private address range?

Using iptables 1.2.7a+ and the NETMAP target:

iptables -t nat -A PREROUTING -d 192.168.0.0/24 -j NETMAP --to 192.168.1.0/24

or

iptables -t nat -A POSTROUTING -d 192.168.1.0/24 -j NETMAP --to 192.168.0.0/24
