Hi,
We have arround 200 openvpn clients using routerboard 750 (v5.24 most of them) connected to a linux box running openvpn server on debian working fine until now!
Some clients (maybe 20% of them) loss conectivity and reconnect to the server over and over again.
We can probe the connection got lost when TCP traffic goes inside the vpn tunnel. We send UDP and ICMP traffic without any problem.

Anyone had a similar problem ?
Thanks in advance.
