RE: Reaching Behind Router

If  a PC has IP addressing which is not advertised to the outside , which means
it is typically setting behind a firewall OR router, than there isn't much one
can do unless you can get the Firewall OR Router admin to " statically NAT " a
public routable IP address to your PC's private IP. There's already a NAT type
of action taking place, but its a dynamic one, probably with a POOL of public
addresses. Of course , this now starts to unprotect your PC, as it becomes KNOWN
to the outside world. But, if you NAT an address to a particular TCP PORT on
your PC, pick one that your program opens the socket on, then you'll still be
fairly protected.

Good luck !!!

Subject: Reaching Behind Router





I'm trying to get two programs to contact each other, but my PC is behind
a router. So, the IP address I get is either for the internal network,
which can't be used by someone outside to contact me, or the IP of the
router, which won't necessarily know to route to my PC.

So, how do I get two PCs communicating with TCP/IP when one or both are
behind routers?
