Our usage is peaking around 3600 right now. We have been trying to come up with some kind of a NAT solution since that number is only going to go up, and quickly because we're working on tripling our number of wireless access points. We don't have a good solution yet but I wanted to let you know you're not the only ones in that boat. If we do find a viable solution I'll share here.

Thanks for all of the responses- I wonder if anyone with a peak usage like ours is doing NAT- almost 6500 clients? -Lee ________________________________________ From: The EDUCAUSE Wireless Issues Constituent Group Listserv [wireless-...@listserv.educause.edu] On Behalf Of Jason Appah [jason.ap...@oit.edu] Sent: Monday, December 14, 2009 11:03 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Private IP space for wireless users- anyone? Yes, that is what we do. I just wondered how big if a bear it would be to track pat in a university wireless environment. In a second related note, we recently changed our NAT timeout from 3 to 2 hours as we were beginning to run out of 1 to 1 NAT ranges Sent from my iPhone Jason Appah Systems Administrator Oregon Tech On Dec 14, 2009, at 6:33 PM, "Phil Trivilino" <p...@stlawu.edu> wrote: > We do 1to1 dynamic NAT on the ASA firewall and log all the > translations to a syslog server.
