I looked for the info on DMZ....  I'm a little confused.... many articals..... do you turn "on" DMZ on the 2wire and the linksys?    The notes only talk about DMZ on linksys 54   ......  My linksys router is WRT400N no help in linksys site only reference to the 54 product.    seems like the DMZ on the 400 works a little different looking at the settings.....   Can you help me?   Can you explain what DMZ is?   Thanks for any help
