W4K - Open VPN APP

[victor.back]

Good day everyone,
I plan to write Open VPN for W4K applications.
(for schneider hardware is no way how to download KNX instalation remotely)
The application will run a second ovpn instance with user settings.

I have a few questions to EMBS.
1. how to get log from ovpn? Filter from system log?
I tried:
openvpn --config client.ovpn --log /var/log/openvpn.log
and
"status /var/log/openvpn/openvpn-status.log" in config file
both without success
2. how to make cyclically loaded log content into the application?
3. I plan to edit the configuration, by modal window. can you provide me some template?
4. is any way how to generate certificate directli on W4K? Open SSL?
5. in case of server configuration, need to make an entry in iptables?
6. The knx multicast does not go through tunnel, is there any way to solve it? ( usetap tap?ap )

Thank you very much.
