Hi
i got another issue related to my upgrade to 18.06-rc2.
there is something odd going on with openvpn.
first of all syslog contains "IP packet with unknown IP version=15 seen"
some searching indicates this is related to comp-lzo setting in openvpn.
i already have comp-lzo specified in the config file /etc/config/openvpn but
this appears to not make it all the way to the generated file.
so generated file under /var/etc/openvpn-vpnserver.conf does not contain
comp-lzo and that is likely why openvpn server complains with:
WARNING: 'comp-lzo' is present in remote config but missing in local config,
remote='comp-lzo'
when a client connects (there is also a warning about inconsistent link-mtu but
i suspect thats something else)
according to this page:
https://community.openvpn.net/openvpn/wiki/DeprecatedOptions
comp-lzo a depreciated option and i suspect i should be using "compress lzo"
instead to make my openvpn 2.3 client happy.
so, how do i fix the comp-lzo setting?
i have figured it out but i still think there is something that needs fixing.
i fixed the problem by setting the "compress" setting manualy to "lzo"
this setting is not available via web gui so you have to use uci
like so:
uci set openvpn.vpnserver.compress='lzo'
uci commit openvpn
since comp-lzo is depreciated i think this option should be removed from luci
web interface and replaced with compress instead.
possibly adding some logic to convert from "comp-lzo yes" to "compress lzo" or
similar.
or just leave it and let user deal with it, possibly with a note somewhere that
you may have to do this manually depending on client versions used.
