.IR icmp_errors_use_inbound_ifaddr " (Boolean; default: disabled; since Linux 2.6.12)"
.\" The following taken from 2.6.28-rc4 Documentation/networking/ip-sysctl.txt
If enabled, ICMP error messages are sent with the primary address of
the exiting interface.
If non-zero, the message will be sent with the primary address of
the interface that received the packet that caused the ICMP error.
This is the behavior that many network administrators will expect from
a router.
And it can make debugging complicated network layouts much easier.
Note that if no primary address exists for the interface selected,
then the primary address of the first non-loopback interface that
has one will be used regardless of this setting.
