Suggested correction

Description of problem:
The ifup-ipsec script creates a routing table entry for tunnel mode interfaces, apparently in order to set the source address for packets originating from the gateway. When a host in the local network sends an IPv4 packet destined to the remote network, the gateway sends an ICMP redirect message instructing the sender to send directly to the destination rather than via the gateway. Some devices, such as Android devices, still update their routing tables upon reception of ICMP redirects.

Version-Release number of selected component (if applicable):
0.8.2-1.fc21

How reproducible:
Configure a tunnel mode IPsec interface and send IPv4 packets from an Android device to the remote network.

Actual results:
After a few packets, the Android device stops routing the packets via the gateway and starts sending ARP requests instead.

Expected results:
All packets get routed via the IPsec gateway and no ICMP redirects are sent for the tunnel-bound packets.

Additional info:
The suggested correction is to disable the sending of ICMP redirects on the local network's interface.

Comment 1 Fedora End Of Life 2015-11-04 10:55:23 UTC
This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '21'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 21 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 2 Jan Kurik 2016-02-24 15:41:44 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.
