Source routing is a security feature used on computer networks to provide more reliable and secure communications. When a packet is sent between nodes on a network, the source address of the packet is usually determined by the IP address of the node that sent the packet.
However, if the packet is destined for a node that is behind a firewall, the source address of the packet may not be the IP address of the sender. Instead, the source address of the packet may be the IP address of the firewall.
This is where source routing comes into play. When a packet is sent from a node that is behind the firewall, the firewall can use source routing to determine the source address of the packet.
The firewall then can send the packet to the correct node, based on the source address of the packet. This is a more reliable way of sending packets, because it eliminates the possibility of a packet being sent to the wrong node.
