How does Linux choose source IP?

Based on the routing information to the target the kernel picks the outgoing network interface and then assigns the IP address of this interface as source IP. If the interface has multiple IP addresses configured the first one is used, although the internal order of the IP addresses might not be obvious.

What are routes in Linux?

Routing is a means of sending an IP packet from one point to another. For instance, when you send an e-mail message to your friend in another country or even across the street, you are transmitting a series of IP packets, or datagrams, from your computer to your friend’s computer.

How TCP IP selects a source IP address?

over which the initial packet is sent. For an IPv6 packet, TCP/IP uses the default source address selection algorithm to select one of the addresses configured for the interface over which the initial packet is sent.

What is reverse path filtering?

The reverse-path-filtering command determines whether incoming packets with a source address that cannot be routed by that interface are accepted and processed. Enabling this option effectively disables source routing because the DataPower® Gateway ignores such packets.
