I don't have to look further down.

If port forwarding is required for an application to work (often handled 
by uPNP), then LSN will break the communication. PS3 has required such 
functionality right along with the xbox and Steam.

There are many games out there that also host on a specific end node 
automatically. They are able to accomplish this due to uPNP and 
automated port forwarding. They will break in LSN environments.

with it)
