A malformed packet is a type of network packet that does not adhere to the expected format or structure for that particular type of packet. A network packet is a unit of data that is sent over a network from one device to another, and it includes a header that describes important information about the packet, such as the source and destination IP addresses and port numbers.
A packet can become malformed due to a variety of reasons, such as errors in the network, hardware, or software that cause the packet to be constructed incorrectly. Malformed packets can also be created intentionally by attackers as part of an attack, such as a buffer overflow attack or a denial-of-service attack.
When a device receives a malformed packet, it may not be able to interpret it correctly, which can cause issues with the network, such as slow performance, errors, or even crashes. Malformed packets can also be a security risk because they can be a sign of an attempted attack or can be used to exploit vulnerabilities in the network.
Network administrators often monitor their networks for malformed packets as part of their overall network security strategy. Network security devices such as firewalls and intrusion detection systems can detect and block malformed packets to protect the network from potential threats.

Situation: The client has FatPipe connecting to 3 IPSs. They would like to know how to configure FatPipe to use WAN 3 as primary gateway.
To force the use of a FatPipe WAN 3, you can follow these steps:
Configure your network devices to use the FatPipe WAN 3 as the primary gateway.
Ensure that your network devices are configured to use the FatPipe WAN 3 as the default route for all traffic.
Configure your network devices to prioritize traffic over the FatPipe WAN 3. This can typically be done using Quality of Service (QoS) settings.
Monitor your network traffic to ensure that all traffic is being routed over the FatPipe WAN 3. You can use network monitoring tools to do this.
To configure a FatPipe WAN 3 as the primary gateway, you can follow these steps:
Connect the FatPipe WAN 3 to your network. This typically involves connecting one of the WAN ports on the FatPipe WAN 3 to your router or modem.
Log in to the FatPipe WAN 3 management interface. This can typically be done by opening a web browser and entering the IP address of the FatPipe WAN 3 into the address bar.
Navigate to the “Gateway” or “Routing” section of the management interface. This will allow you to configure the FatPipe WAN 3 as the primary gateway for your network.
Configure the WAN ports on the FatPipe WAN 3. You will need to configure the WAN ports on the FatPipe WAN 3 to match the settings of your ISP. This typically involves setting the IP address, subnet mask, default gateway, and DNS server settings.
Configure the LAN ports on the FatPipe WAN 3. You will also need to configure the LAN ports on the FatPipe WAN 3 to match the settings of your local network. This typically involves setting the IP address, subnet mask, and DHCP server settings.
Test the configuration. Once you have configured the FatPipe WAN 3 as the primary gateway, you should test the configuration to ensure that it is working correctly. This typically involves checking that you can access the internet and that traffic is being routed through the FatPipe WAN 3.
