Hi!
I`m using OpenVPN for NVR video from IP cam.
My network diagram:
With a small load tunnel works fine.
But when I open IP cam web interface with video stream, bandwidth reach 3-4MBit/s and after 1-3 minutes tunnel crashes.
I expect stable tunnel from OpenWrt till 8MBit/s, but it crashes on 3-4MBit/s.
If I close IP cam web interface tunnel restores.
My configs:

What can be the reason of this crashes? Performance issues on OpenWRT routers on incorrect configuration of OpenVPN?
Do I need more powerful hardware?
