Hi, I have applied these 5 patches to master on ubuntu 18.04LTS The resulting binary gave server+client ipv6 *only* tunnel over ipv4 network. 100% success
Using only: --server-ipv6 12fc:1918::10:186:0:0/112 I am sure buildbot runs more extensive tests than my single test but I would be happy to ACK this if i could work out how to. Thanks On 05/06/18 10:04, Antonio Quartulli wrote:
This patchset allows clients and servers to work with a tunnel configured with IPv6 only. Patches 2 and 3 are mere cosmetic changes and could be merged regardless of the rest (note that 3 depends on 2). With this change a server can be configured by using only the '--server-ipv6' directive. This will result in clients receiving only 'ifconfig-ipv6' setting in their push-reply (and no IPv4 at all). Given that different components required changes in order to achieve this goal, the patchset has been organized as follows: - patch 1 alters the tun logic (client & server side) - patch 4 alters the ifconfig-pool logic (server side) - patch 5 alters the server config logic (server side) Although I have tested the patchset with different configurations and with our buildbots, such change would definitely benefit from a broader testing campaign (even before being merged).
