Hi all. Im just learning linux. Been using it for about 3 months, and ran into a problem.... Can Anyone Help??
I am running a web server that is inside a LAN and want to make it accessible to the Internet. The web/ftp/mail server is behind another linux box which also is the one that shares the Internet connection. Everyone in the LAN can access the web/ftp/mail server pages. But it can not be seen from the outside world.

example setup I have

192.168.0.1 = Main PC/Internet Connection Sharing
ppp0/Dynamic IP/DYNDNS.org for dynamic service
eth0 NC to hub
OS = Mandrake 9.1

192.168.0.3 = web/ftp/mail server "Sambar 6.3"
ports: web = 80, SMTP = 26, nntp = 119, pop3 = 110
eth0 NC to hub
gateway = 192.168.0.1
OS = Mandrake 9.1

192.168.0.4 - 192.168.0.12 = other PC's
gateway = 192.168.0.1
NC to hub
OS = Windows ME, 98, XP

Any,ANY Help would be greatly appreciated. Been working with this for over a month
Thanks In Advance

You will need to use either iptables or ipchains (depends on your kernel) rules on the machine with the net connection to forward requests based on ports to your server.
