Yesterday I thought it might be fun to set up my home network again. It's been idle for a few years, and I wanted to play with some configuration options before I attempt them at work. I tried for hours to make a Win2K machine connect to the server with no success. Everything set up correctly, but no connection. Using automatic addressing wasn't working - DHCP didn't seem to be responding. Static addressing allowed me to ping by address, but not to browse, and routing wasn't working at all (using NAT to share an Internet connection).

As a last resort I opened up Sygate Personal Pro to view the packets being exchanged on the network and discovered that everything from the client host was being blocked! Since the local interface was disabled when I installed it, I assumed that SPP only monitored the WAN interface. Wrong! It doesn't automatically discriminate between NICs; it blocks all packets regardless of source if a service is blocked. I had blocked DHCP, WINS, and DNS long ago when I found my machine serving the rest of my ISP's network, so now it was blocking my own internal network traffic.

Fortunately there is an Advanced settings tab that allows me to define which subnets and ports are allowed to access various services. Using that tool for each service running will be tedious, but it should allow me to block external traffic while permitting my own subnet to work smoothly.

Just a word to the wise if you find yourself tearing your hair out over a network that you know is set up correctly, yet refuses to connect. Check for a firewall running and disable it briefly before setting fire to the building!

Some people think of it as a six-pack; I consider it more of a support group.
