Priority: normal X-mailer: Pegasus Mail for Win32 (v2.54) Sender: owner-freebsd-isp@freebsd.org X-Loop: FreeBSD.org Precedence: bulk After filling out Yet Another Justification for more IP space, I'm looking for ways to squeeze our current utilization even tighter. One possibility I've been thinking about is installing a FreeBSD server with natd and two NIC's on our network and putting most of our dialup terminal servers behind it. Any customer who's being assigned a dynamic IP would be given a number from a hunt group connected to one of those termservers, and their address would be assigned out of the 10.x.x.x space. Web surfing and email should work fine, but what about other services, such as IRC, ICQ, whatever. Would this cause a problem with backtracking a problem user through DNS? Is anybody else doing this, and if so, how successfully? Logan Ashby http://www.texramp.net lashby@texramp.net sysadmin@texramp.net =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
