Or, following is one more command to enable temporary:<\/p>\n
| echo 1 > \/proc\/sys\/net\/ipv4\/ip_forward<\/pre>\nThe temporary change, of course, means that the parameters will return to their default value when the machine restarts or \u201csysctl\u201d restarts if it is done manually.<\/p>\n
Now, let\u2019s check out the Permanent Solution for it.<\/p>\n
Permanent Activation<\/strong><\/h4>\nTo enable these changes permanently, you have to modify the configuration file of sysctl so that it loads our modifications each start. It is the file \u201c\/etc\/sysctl.conf<\/em><\/strong>\u201d to activate IPv4 IP forwarding. We will add or uncomment this line:<\/p>\n| net.ipv4.ip_forward = 1<\/strong><\/pre>\nFor IPv6, we will do the same with this line:<\/p>\n
| net.ipv6.conf.all.forwarding=1<\/strong><\/pre>\nThe configuration can then be reloaded so that the changes take effect immediately:<\/p>\n
| sysctl -p \/etc\/sysctl.conf<\/strong><\/pre>\n![\"linux-3\"](\"https:\/\/ownwebservers.com\/kb\/wp-content\/uploads\/2021\/09\/linux-3-300x183.png\")
