WithGate provides firewall security and Internet connection sharing
(modem sharing, cable-modem sharing, ISDN sharing, or ADSL) on your LAN.
This allows you to connect anyone on the network to the Internet with only
one ISP account and one modem. After installing WithGate, anyone on the
local network will be able to transparently and securely access the
Internet. The built-in firewall can prevent resource exposure and defend
from an attack. Withgate supports most applications and protocols like DNS,
HTTP/HTTPS, Telnet, SMTP, POP3, NNTP, ping, traceroute, MSN Game Zone,
Battle.net, Westwood online, FTP, RealPlayer, QuickTime, ICQ, Napster, and
IRC. The configuration wizards make it easy to set up, so you can have the
program running in minutes. WithGate also performs dial on demand, and
automatically hangs up when the idle time reaches the maximum value.
