I've just gotten a major lesson in doing this. Basicly, what I've found out is, you are just as well of to use the -nat switch on PPP. You'll have to make sure that your MTU's are set properly on all NICs (see the handbook), but other than that it's straight forward. You can use nat port tcp internal.host:ftp ftp to forward ftp'ing to an internal host, same goes for web, and other ports you want forwarded to specific machines. Kuzak wrote: > > The layout...
