Andrew,

Because the control channel runs over TCP, NAT/PAT boxes typically don't
have a problem with it. But because the data tunnel (which transports

end

user traffic over PPP) runs over GRE (IP  port 47), NAT/*PAT* boxes may

have

problems translating data tunnel packets.


That's IP protocol 47, if it was just port 47, then you'd still just be 
talking about a TCP port
