Between 1985-1988, CERN, the European Laboratory for Particle Physics in Geneva, expanded TCP/IP throughout their network CERNET, but no outside connections were allowed using TCP/IP. In 1987 Ben Segal, CERN's TCP/IP Coordinator met with Len Bosack, founder of a small company called Cisco Systems. At the time Cisco was a 20 employee company making routers and IP filtering systems. CERN needed two IP routers to act as IP filters between CERN's public Ethernet and a new secure IP segment for a new Cray Supercomputer. This was a major step for TCP/IP at CERN, connecting their ethernet to a very secure environment using this protocol. In 1988, Ben Segal had a visitor Daniel Karrenberg, the system manager of "mcvax", a celebrated machine at the Amsterdam Mathematics Centre that acted as the gateway for all transatlantic traffic between the US and European sides of the world-wide USENET. Karrenberg wanted to convert the European side (EUnet) into an IP network which the US side were doing also, but he needed the hardware to allow him to run IP over some lines that used X.25. Segal pointed him to Cisco, which had the routers and the European IP network begun. In January 1989, CERN opened up its first external connections to the Internet.
