search in the following:
|
1 |
# Net.ipv4.conf.default.forwarding = 1 |

net.ipv4.conf.default.forwarding = 1 |
save and exit with the command:
ctrl + x, type y and press enter
make sure the number after the equals sign “=” is 1It means that

after that, you still have to make / insert script for routing
so that the PC would know where in the routing network
type the following command [change as needed]
|

/sbin/iptables-t nat-A POSTROUTING-s 192.168.168.0/255.255.255.0-d 0 / 0-j MASQUERADE |
His explanation like this:
-T nat= Is the manufacture of nat table in iptables
-A POSTROUTING= This will add a new rule in the POSTROUTING
-S 192.168.168.0/255.255.255.0= The ip address in the routing client that will be between 0-255. can also be written 192.168.168.0/24
-D 0/0 = This section will seek out the source package. command 0 / 0 means it will search in global form.
-J MASQUERADE= This command will direct the chain gets a certain package, but without source.
completed, but wait a minute, the configuration using iptables just now is only temporary, so if the server on reboot the pc, its settings will be lost
well
so that the configuration is always done from the start pc in turn
