Re: Where NAT disenfranchises the end-user ...
Yep- NAT showed up in Cisco IOS in the 11.2 version. I am definitely not an expert on this subject, but a couple of things come to mind when running through these posts: NAT is almost always (or needs to be) configured in an overload state (or PAT). If your NAT pool should become to small for your users (good rule of 10 users to 1 IP), you can always check the translation statistics & start to move you pool accordingly. Unless I'm missing some sort of breach with the occasional port table (when overload begins) it works quite well with users heading to the Internet. As far as the history of NAT, it's a band aide that offers some security (sucks to trouble shoot @ times too). NAT is a selling tool today for home users & ISP's that don't want to cough up addresses. As soon as IPV6 comes online, NAT will offer almost no value add. .02 Phil ----- Original Message ----- From: "Adam McKenna" <[email protected]> To: "NANOG (E-mail)" <[email protected]> Sent: Friday, September 07, 2001 3:31 AM Subject: Re: Where NAT disenfranchises the end-user ... > > On Thu, Sep 06, 2001 at 10:29:21PM -0700, Roeland Meyer wrote: > > > > |> From: Eric A.
