I have a network with the following topology:
1. An adsl modem connected through PPoE to internet (outside network);
2. A wireless router connected to the modem;
3. A centOS 5.5 server directly connected to one of the router's port;
4. A few laptops and desktops of Windows 7 OS connected to the router wirelessly.
I want to have someone connect from outside to the CentOS server. I was told to set up IP forward in the router so that it can work.
But how to set up the IP forward?
