help: ubuntu as a server connecting local network to internet

ctdarksilver · 10-24-2005, 11:56 AM

Now I have a small network within my friends in my college hostel. Currently using a router to connect to ADSL. However I found the router is so lousy that it does not have an iptable and decided to use my computer as a server for easy management.

Can anyone tell me how can i do it since I am still a newbie.

I am using kubuntu 5.10, with one ethenet cable and one wireless card. one router with ADSL modern. another five windows machine all using wireless connection

In the LQ Wiki are sections about making a firewall and sharing the internet connection with NAT..

eg http://wiki.linuxquestions.org/wiki/..._a_gateway/nat

when I did

Code:

echo 1 > /proc/sys/net/ipv4/ip_forward</userdefined

I got

Code:

bash: /proc/sys/net/ipv4/ip_forward: Permission denied

even I use sudo.

Further more, I am not quite understand the "Firewall Script" part, is it a file? where is it? or is it terminal command? Is there any simplier step-by-step how-to since I am still a newbie?
