Sure this source *and* destination NAT'ing is possible with iptables
trickery on both sides. Heaving NAT'ing doesn't mix well with hope though ;)

Since it needs to happen on both sides, this "solution" isn't very home
user friendly, IMHO.

This page also warns about how confusing this setup is:

Since home network gear generally uses 192.168.0.0/24 or 192.168.1.0/24
I would assume that not many users have an IP collision with your office
network. If that's the case it would probably be easier to make the IP
change on the client side.

Good luck,
