I have a shiny new 15″ MacBook Pro, my first Mac. It’s a great laptop and I only have one major complaint, hardware wise: Only a single button for the trackpad?!! Oh well, I’m going to be plugging in a proper mouse soon anyway. The real issues I’ve been having are with the OS software.
I have a small network connected via a combined ADSL modem/4-port router. I run the router in a mode called “half-bridge” which essentially means that the router forwards all traffic coming up the ADSL link onto the LAN directly, without modification other than de-encapsulating the packets from the PPP link. My NAT server (running linux) therefore listens for incoming traffic on the WAN address as well as its own LAN address. The router must also pick up packets destined for the WAN and forwards them on down the ADSL (PPP) link. Naturally the NAT machine is the only machine that sends packets destined for the WAN: all the other machines on the LAN use the NAT box as a gateway; this allows NATting and traffic regulation etc.
If you already know what the problem is that I’m about to describe, I think you’re doing pretty well. Read the rest of this entry »
