well, ok. See, you have an packet, going throuh the rules, top-down.  it 
first hits REJECT rule (and is rejected), and it never makes it to the 
ACCEPT part. 
I recommend that you install ipmasq package (at least in sid it works w. 
iptables) and see how it works. (good example is worth tons of mail, I 
think ;))
