I installed BellSouth DSL and connected the wired modem to my 802.11n Airport Extreme. It kept giving me one error that said Double NAT. I called BellSouth and they told me that NAT was not enabled on the modem and I didn't turn it on as an option on the Airport (as I really don't understand what it is) but after I applied the settings, it came up as an error. It gave me the option to ignore it and I checked that, I then updated the Airport again and now everything is fine. The light on the front is GREEN....that's GOOD. But still, what is NAT and what does it mean to me?<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Thanks for your time,</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>--</DIV>Tim Collier<BR class="Apple-interchange-newline"><DIV>Mac Pro 2.66</DIV><BR class="Apple-interchange-newline"></SPAN> </DIV><BR></DIV></BODY></HTML>
