You could > get traffic to them, but just no replies through the router. No, 10% of machines out on the big bad Internet don't work. (I'm guessing at the 10% number. It may be higher/lower, but about 10% of the sites I try to contact don't work.) 90% of the sites *OUTSIDE MY NETWORK* that I attempt to contact on these internal machines work, and all of my network machines can talk to one another. > If you sit at the router, can you ping those systems (assuming > they can be pinged)? If I sit on the machine who can't make the WWW connections I can ping the remote sites if they haven't blocked out ICMP packets to me. I simply can't make TCP connections to them.
