Strongswan issue #1220 (packet loss on AWS)
Closed, ResolvedPublicBUG
Actions

Description

Ok so I open a bug report for V1.2.x. As closing https://phabricator.vyos.net/Q79 was not very helpfull. In VyOS blog I read cloud installs are very important for this project. (I agree in this)

As wrote in Q79 the problem persists in the latest nightly build. Details see https://phabricator.vyos.net/Q79

further updates on https://wiki.strongswan.org/issues/1220.
There is a kernel patch for the xen-netfront bug: https://patchwork.kernel.org/patch/9338979/. Maybe a backport to 4.4 would be the solution for VyOS.

I can help with tests are welcome.

This Tasks seems to be resolved since kernel 4.14, as the xen netfront bug in kernel is fixed in this version (https://patchwork.kernel.org/patch/9338979/).
I tested with latest nightly on AWS. No packetloss anymore with AES!
