Source Routed Packets

IP Source Routing is a standard option in IP that allows the sender of a packet to specify some or all of the routers that should be used to get the packet to its destination.

This IP option is typically blocked from use as it can be used by an eavesdropper to receive packets by inserting an option to send packets from A to B via router C. The routing table should control the path that a packet takes, so that it is not overridden by the sender or a downstream router.

To configure source-routed packets:

1. Navigate to Network > Firewall > Advanced.

2. Scroll to Source Routed Packets.

3. Ensure the Drop Source Routed IP Packets option is selected. This option is selected by default.

   If you are testing traffic between two specific hosts and you are using source routing, deselect this option.

4. Click Accept.
