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 -jamie-
