Lewis,I guess that statement refers to the various issues with NAT and traversal of point-to-point services (NAT-T, such as for VPN tunnels). NAT can be a bear to deal with in this regard, mainly due to implementations where RFC3235 has been ignored or taken too lightly (see http://www.isi.edu/in-notes/rfc3235.txt). NAPT (the most workable form of NAT) is not used nearly enough in small gateway devices (or even in some of the larger boxes), leading to port translation issues (i.e., the far end cannot remap an incoming port when the necessary port is already in use by something else - and other such fun).
According to the presentation you linked "NAT is evil" Why is that? Why would designers hate it?
Thanks,
Sam
