Sygate 3.11 in fact not just 3.1 ;)

This full-featured program supports dial-up, ISDN, cable modem, xDSL, or even dedicated Ethernet connections, and it requires virtually no setup or maintenance. It also supports NetMeeting, iPhone, Net2Phone, running servers on SyGate clients, pcAnywhere, and more. SyGate 3.1 adds Windows 2000 (release candidate) and SOCKS 5 support and is compatible with SyShield. SyGate 3.1 features a newly added Diagnostics module to help users setting up the LAN.
