Hi all,<br />
<br />
problem sorted out. The root cause is not on this raspberry pi, rather it is on the firewall. Default gateway is defined correctly, with routes work perfectly. This is what we sorted out.

Thanks for expert - Dr Klahn in pointing out that the default gateway is working. Yes, nothing wrong with the raspberry pi, instead, the firewall is the culprit.

<div class="content wysiwyg-content">
This is using a raspberry-pi. My co-worker has defined a bridge called br-lan on top of the physical eth0. Please see attached docx for ifconfig command. Please also see the networking settings on /etc/network/interfaces, /etc/network/interfaces.d/<wbr />br-lan, and /etc/dhcpcd.conf files. See the ip addressing settings of br-lan as follows:<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp;ip - 192.168.100.199<br />
&nbsp; &nbsp; &nbsp; &nbsp;mask - 255.255.255.0<br />
&nbsp; &nbsp; &nbsp; default gateway - 192.168.100.2<br />
&nbsp; &nbsp; &nbsp;dns - 203.211.152.66<br />
<br />
However, the default gateway setting doesn't seem to work. Please see the results of route -n. I also try to set br-lan to dhcp, and the result is, eth0 grabs the ip - 192.168.100.199.<br />
<br />
Appreciate for any help. Thanks in advance.

Why adding default gateway for raspberry pi failed?

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things.

Ubuntu

The Raspberry Pi Foundation works to put the power of digital making into the hands of people all over the world, so they are capable of understanding and shaping our increasingly digital world, able to solve the problems that matter to them, and equipped for the jobs of the future.

We provide low-cost, high-performance computers that people use to learn, solve problems and have fun. We provide outreach and education to help more people access computing and digital making. We develop free resources to help people learn about computing and how to make things with computers, and train educators who can guide other people to learn.

Raspberry Pi

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Operating Systems

Multimedia applications are those programs that integrate more than one media at a time; browsers are the most obvious. However, the term has come to include the use of programs that enable the use of any component that isn’t simple text and static graphics, such as audio, video, animation, virtual reality, conferencing and monitoring.

MultiMedia Applications

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.
