I found some useful information here:

http://www.csse.monash.edu.au/~ctwardy/mol-debian-benh.html

The NAT issue in my case was fixed by installing ipmasq and dnsmasq
(both in universe I think). When I installed those two packages, mol
sprang to life and connected! By using the info on the monash page in
conjunction with the wiki guide, I was able to get it up and running. 

(I also tried installing the dhcp daemon, but the two packages I mention
above did the trick for me. DHCP didn't start for me either.) Hope this
works for you as well!
