If the default gateway is not working after being set, it could be due to incorrect gateway configuration or unstable network connection. Here are some possible solutions:<\/p>\n

    \n
  1. Check the gateway configuration to ensure that the correct gateway IP address is set in the \/etc\/sysconfig\/network-scripts\/ifcfg-eth0 file, and that the gateway address matches the network interface configuration.<\/li>\n
  2. Restart network services: You can try restarting the network services to apply the new gateway configuration. Run the following command:<\/li>\n<\/ol>\n
    sudo systemctl restart network\r\n<\/code><\/pre>\n
      \n
    1. Check the network connection: make sure the network connection is working properly, the Ethernet cable is connected correctly, and the gateway IP address is accessible.<\/li>\n
    2. Check the firewall settings: If using a firewall service, ensure that the gateway IP address is allowed through the firewall.<\/li>\n
    3. Check the routing table: Use the command “route -n” to view the routing table and confirm if the gateway routes are properly configured.<\/li>\n<\/ol>\n
      If none of the above methods resolve the issue, you can try restarting the server to apply the configuration changes. If the problem persists, it may be necessary to further investigate network settings or check system logs for more information.<\/p>\n","protected":false},"excerpt":{"rendered":"
