It appears it's more than just after boot, tap interfaces seem to always end up missing "UP". Will attempt to further quantify later.

Dmitriy: which type(s) of OpenVPN instances are those?

there is a test case for this on 22vpntest. The tap interfaces are missing "UP" in flags.

# ifconfig ovpns10 
ovpns10: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=80000<LINKSTATE>
    ether 00:bd:b1:06:00:0a
    nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
    media: Ethernet autoselect
    status: active
    Opened by PID 32872
# ifconfig ovpns10 up 
# ifconfig ovpns10
ovpns10: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=80000<LINKSTATE>
    ether 00:bd:b1:06:00:0a
    inet6 fe80::2bd:b1ff:fe06:a%ovpns10 prefixlen 64 scopeid 0x14 
    nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
    media: Ethernet autoselect
    status: active
    Opened by PID 32872

it works after the "ifconfig up"

I repeat myself: bridged tap client doesn't work after reboot!

Yes, latest commit brought the UP flag to the interface but there is no traffic between sites until instance restart.

before instance restart/after reboot:

ovpnc1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=80000<LINKSTATE>
ether 00:bd:ac:6d:00:01
inet6 fe80::2bd:acff:fe6d:1%ovpnc1 prefixlen 64 scopeid 0x9
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
media: Ethernet autoselect
status: active
Opened by PID 14515

after instance restart:

ovpnc1: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=80000<LINKSTATE>
ether 00:bd:ac:6d:00:01
inet6 fe80::2bd:acff:fe6d:1%ovpnc1 prefixlen 64 scopeid 0x9
nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
media: Ethernet autoselect
status: active
Opened by PID 31233

Latest snapshot.

same goes for bridged tap server: everything is UP and RUNNING but no traffic after reboot. Restarting server fixes the problem.

Yes, of course. Since this bridged/TAP OpenVPN nonsense needs PROMISC on both the ovpn and other bridged interfaces -- which is apparently not set.
