Cascaded uPnP port restricted NAT. [Jan. 11th, 2009|09:03 pm]

HAHA! We DID IT! yay!
Thanks to a very helpful post here:

We nowhave one nat table, one forwarding table, a little dnz and no redundancy. =)

We've been setting up out Linksys ADSL Modem (AM200)(blue box) and dd-wrt enabled WRT54G-TM router (silver box).
Ouch, it's complicated!

We've still not got uPnP to work yet.
It's enabled on the blue-box, and was on the silver-box. But the silver-box kept dropping GET requests from my computer!
We turned off uPnP on the silver-box, and it all works fine now - except we no longer have working uPnP to the Internet. =(

Messenger network discoverer thingy said "Connected through cascaded uPnP port restricted NAT."

Um, we need to read a lot!

OMG! It's moving! [Jan. 11th, 2009|10:44 pm]
In a major turn of events from Saturday, Xatrox towers was a hive of activity today.
We've upgraded the RAM in our machines, and I found out why my new(made from old spare parts - but still new to me) computer was failing to boot.
The SATA cables are rubbish! the connector is flimsy, and the cable is rigid. Any movement on the cable will move the connector, and if it doesn't break you will at least get an intermittent connection.

I've made my first electric circuit with the breadboard and parts that arrived last week, and my laptop that was really laggy in work (swapping between windows would cause the GUI items to be drawn one at a time!), have totally failed to surface on our network at home.

We've done lots of tidying up - and now I'm really tired. I even took pictures of our progress with the computers and electric circuits, but I'm too tired to post them now. Hopefully I'll have the spoons to do it tomorrow night.
