FreeBSD, now in production version 10, can be configured with a very small amount of hardware to support and to run an ISP. Having run a regional ISP for 20 years on FreeBSD without the use of other more expensive gear, I am uniquely able to advise on how to setup your ISP on a strict budget. - Engage fully by providing full dual-stack IPv4 and IPv6 - Manage your ISP with PostgreSQL - the most advanced open-source database - Speak BGP to your peers --- pay less for bandwidth - Manage and sell advanced virtualization products with FreeBSD's jail technology - Start with as little as two physical servers.
