I have a server withh following directive :
push "route 62.210.16.3 255.255.255.255 net_gateway"
When used manually, it works.
When connecting through network manager, I get following log
Apr 11 23:48:28 bibi NetworkManager[2553]: <error> [1428788908.759589] [platform/nm-linux-platform.c:1714] add_object(): Netlink error adding 62.210.16.3/32 via 192.168.0.254 dev tun0 metric 1024 mss 0 src user: Unspecific failure
192.168.0.254 being the local gateway I see the pushed command has
been understood, however NetworkManager is unable to setup the route.
What could be interesting for debug is I also use
push "redirect-gateway def1 bypass-dhcp block-local"
(but I get same result without the block-local flag)
