As the first EZ-B4's shipped, there have been a lot of conversations about connecting to home networks and a good number of just general network questions. I came across a nice article today that gives a basic introduction to home networking that I think is a good start.
It doesn't cover three of the critical items that will come up with EZ-B v4 that have sparked a lot of conversation here. Assigning the same IP to your EZ-B device every time (static DHCP, or some other names) or Dynamic DNS and Port forwarding (needed to access your EZ-B over the internet), but it is a good baseline to refer to before having those conversations.
If I come across good articles on those I will update this thread, or if I don't, I'll sit down and write a general tutorial one of these days if no one beats me to it -- I am looking at you @Rich :).
