## VPN

Microsoft Windows NT and Microsoft Windows® 95 both support PPTP, which is supported by certain remote-access server vendors. Remote-access server vendors are divided into two types, one that supports PPTP and another that supports Layer 2 Forwarding (L2F). A compromise has been reached with L2TP, which is supported in Microsoft Windows NT® 5.0. Sun Microsystems’ SKIP protocol is supported on both Windows 95 and Windows NT as well as on some UNIX platforms, including Sun Solaris and Linux. If both Windows NT and UNIX or the remote-access server of a VPN support the same protocol, they operate compatibly.
