Configure Fedora as a NAT Server

Configure Fedora as the NAT server-Linux Enterprise Application-Linux server application information. For more information, see. 2 K in the lab is always under attack and decides to use linux. After the result is installed with Fedora, no configuration is available. It may be because the version is too new and cannot be found online. After more than two months, I found the configuration method on the Internet. Open-source software really wants to say that it is not easy to love you. The compatibility of versions is too bad, and no one can coordinate it. developers can do anything and help is poor!

1. Modify/etc/sysctl. conf and set

Net. ipv4.ip _ forward = 0
Change
Net. ipv4.ip _ forward = 1

2. Modify/etc/rc. local and add the following content to the end of the file:

Iptables-t nat-a postrouting-o eth0-j MASQUERADE

Eth0 is the NIC connected to the Internet.
