[Solved] client looses connection even if keepalive is set

[TinCanTech]

All I see is this:

Fri Sep 23 09:03:49 2016 us=698988 Initialization Sequence Completed
Fri Sep 23 10:03:47 2016 us=625592 TLS: soft reset sec=0 bytes=49183/0 pkts=718/0

which I have already explained.

not sure to understand...sorry

This is --reneg-sec 3600 (1 hour default). If you want a longer renegotiation window set it as the manual explains.

note this config (ifconfig 192.168.200.6 192.168.200.5) doesn't work at all

This is the correct config for --topology net30 (which you are using, as per your posted log).

unlike the former one (ifconfig 192.168.200.6 192.168.200.1) which dropped after a certain time

This is the incorrect config for --topology net30 and was successfully identified to be the cause of your server dropping your client with --ping-timeout.

Your posted log shows that openvpn is functioning perfectly normally .. If you have a new problem please start a new thread and post complete configs/logs and a description of the problem (in full).

NOTE:
In this thread; All of your Openvpn issues have been resolved.
Please see your posted log which shows:
