This is a security issue, since a user activating the VPN would expect all go through it. When I activate a VPN that doesn't support V6, obviously V6 routes need to be removed entirely to ensure everything goes through the VPN as the user would expect.

That sucks, it would be really awesome if you could do something to fix that..

A machine with IPv4 and IPv6 connectivity and IPv4 VPN connectivity with IPv4 and IPv6 DNS information from the VPN will always attempt to reach hosts via IPv6. > This is a security issue, since a user activating the VPN would expect all go through it. There are two issues, actually: 1) Serving IPv6 DNS records and providing VPN access without IPv6 at the same time is a security problem in the first place. Clients that only use VPN for resources on the network are thus not informed about the IPv6 subnets that constitute resources on the network. Solutions (on the network operator side): a) Avoid IPv4-only VPNs and only provide IPv4+IPv6 VPNs. b) Don't provide IPv6 DNS records on IPv4-only VPNs (and vice versa). 2) When VPN is to be used for all (except local) resources and only IPv4 connectivity is available on the VPN, there should IMO be no IPv6 default route through the local router just as there is no IPv4 default route through the local router. >From the network configuration point of view the second issue is as follows... Expected result: * IPv4 default route through VPN * IPv6 default route absent (as VPN doesn't provide any) Actual result (as I understand the bug report): * IPv4 default route through VPN (good) * IPv6 default route via local gateway (bad) Reply at: https://bugs.launchpad.net/ubuntu/+source/openvpn/+bug/1476769/comments/2 ------------------------------------------------------------------------ On 2015-08-18T14:59:01+00:00 Fedora wrote: This package has changed ownership in the Fedora Package Database.

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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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.
