Mobile IPsec ``split_include`` value of ``0.0.0.0/0`` causes some clients to fail
Added by Jim Pingle over 3 years ago.
Updated 10 months ago.
Description
Currently for mobile IPsec the code sets up subnet and split_include entries for IPv4/IPv6 pools based on the GUI setting for networks to send to clients.
When split_include has a value of 0.0.0.0/0, some clients will fail to connect. A forum user reported this for the built-in Android IKEv2 client but there may be others.
So we either need to figure out some better logic about what to put in each of subnet and split_include separately or at the very least, do not add 0.0.0.0/0 or ::/0 to split_include.
Also warrants some more research in strongSwan to ensure both of those fields are being used appropriately.

I can't find a client that can reproduce this so I can't confirm a fix. Attached is a patch which will omit 0.0.0.0/0 and ::/0 from the split_include line, or omit the line entirely if that is the only value.
Needs some testing before committing.
- Status changed from New to Feedback
- Plus Target Version set to 21.05
- Plus Target Version changed from 21.05 to 21.09
Nothing committed here yet and only one data point on if it's beneficial. Bumping this one up for the moment. I'd like to find a way to reproduce this and check that it doesn't break existing setups first.
- Plus Target Version changed from 21.09 to 22.01
There are other changes in 21.09 which may fix this, but leaving it open and moving target for now in case it needs additional work. Can remove target and close it if it works OK on 21.09.
- Plus Target Version changed from 22.01 to 22.05
- Plus Target Version changed from 22.05 to 22.09
Still no meaningful feedback here, can keep waiting until someone who can replicate the original problem can confirm if the suggested change helps.
Tested on 22.05 - I couldn't reproduce the original issue using the native (OxygenOS) android 11 IKEv2 MSCHAPv2 client.

Updating subject for release notes.

Still waiting on an affected user to test and offer feedback.

The original reporter(s) of this issue have long since disappeared and nobody else seems to be able to reproduce the problem or offer feedback on the proposed change.
Closing this out for now but we can reopen this if anyone can offer meaningful feedback or specific instructions to reproduce the problem.
