Here’s how you can configure ufw<\/code> to forward port 80 (HTTP) and 443 (HTTPS) to an internal server hosted on the local area network (LAN):<\/p>\n

    \n
  1. First, make sure that ufw<\/code> is installed:\n
    \n
    <\/div>\n
    sudo apt-get<\/span> install ufw
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  2. Enable the firewall:\n
    \n
    <\/div>\n
    sudo ufw enable<\/span>
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  3. Allow incoming traffic on ports 80 and 443:\n
    \n
    <\/div>\n
    sudo ufw allow 80\/tcp
    \nsudo ufw allow 443\/tcp
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  4. Configure port forwarding using the following commands:\n
    \n
    <\/div>\n
    sudo iptables -t nat -A<\/span> PREROUTING -i<\/span> eth0 -p<\/span> tcp --dport<\/span> 80<\/span> -j DNAT --to-destination<\/span> 192.168<\/span>.0.10<\/span>:80<\/span>
    \nsudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 443<\/span> -j DNAT --to-destination 192.168<\/span>.0.10<\/span>:443<\/span>
    \n<\/code><\/div>\n<\/div>\n<\/li>\n<\/ol>\n

    Replace eth0<\/code> with the name of your Internet-facing network interface, and replace 192.168.0.10<\/code> with the IP address of the internal server.<\/p>\n

      \n
    1. Save the firewall rules:\n
      \n
      <\/div>\n
      sudo sh -c \"iptables-save > \/etc\/iptables.rules\"<\/span>
      \n<\/code><\/div>\n<\/div>\n<\/li>\n
    2. Configure the firewall rules to persist after reboot:\n
      \n
      <\/div>\n
      sudo nano \/etc\/network\/if-pre-up.d\/firewall
      \n<\/code><\/div>\n<\/div>\n<\/li>\n<\/ol>\n

      Add the following contents to the file:<\/p>\n

      \n
      <\/div>\n
      #!\/bin\/sh<\/span>
      \niptables-restore < \/etc\/iptables.rules
      \n<\/code><\/div>\n<\/div>\n
        \n
      1. Make the file executable:\n
        \n
        <\/div>\n
        sudo chmod<\/span> +x \/etc\/network\/if-pre-up.d\/firewall
        \n<\/code><\/div>\n<\/div>\n<\/li>\n<\/ol>\n

        After these steps, incoming traffic on ports 80 and 443 will be forwarded to the internal server at IP address 192.168.0.10<\/code>.<\/p>\n","protected":false},"excerpt":{"rendered":"
