impossible -- if clients are totally NAT ignorant, there is no help
to them. Minimum requirement is they are symmetric, which is fullfilled
by most existing implementations today (I was told one vendor did not
do it till now). Ideally, they do better than that and support 
rport, STUN, and are genereally well implemented.
