Those that aren't savvy would be calling support to complain that they get disconnected every six hours. You would have to tell them the truth, I would imagine, regarding your max session length. Used to work tech support many moons ago when some of our customers had a similar setup for dialup. It does NOT make for happy customers, I can assure you. Imagine you are downloading that large file via HTTP. If it takes long than six hours, you will never be able to download it on your service.</font><br><br><div style="color: rgb(0, 0, 0); font-family: 'Andale Mono'; font-size: 10pt; "><br></div><hr id="zwchr" style="color: rgb(0, 0, 0); font-family: 'Andale Mono'; font-size: 10pt; "><blockquote style="border-left-width: 2px; border-left-style: solid; border-left-color: rgb(16, 16, 255); margin-left: 5px; padding-left: 5px; color: rgb(0, 0, 0); font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica, Arial, sans-serif; font-size: 12pt; "><b>From: </b>"Yannick CHAMPS" <yannick@viti.pf><br><b>To: </b>dhcp-users@lists.isc.org<br><b>Sent: </b>Wednesday, February 15, 2012 3:45:39 AM<br><b>Subject: </b>Re: change ip address every 6 hours<br><br>Yes, I can imagine that<br>I am mainly a technical guy trying to see what is possible or not.<br>Managers will decide, it's their job to put that in production or not.<br>I know this is very bad and against many RFCs but once again let's focus<br>on what is possible to do or not and how to do it.<br><br><br>Le 14/02/2012 22:30, Rudy Zijlstra a écrit :<br>> On 02/15/2012 09:27 AM, Yannick CHAMPS wrote:<br>>> 1.
