Hi to all!
After upgrade from ROS 6.7 to 6.9 on my RB450 openvpn server can't hold any incoming connections
in log (debug) only connection established -- logged out (from my clients ip)
on clients side in log: peer disconnected
openvpn mode is ip
firewall open for incoming server port
auth md5 and RSA cert with my PKI / second level auth: login/pass
all certificates (server and CA) hold in place
all ppp outgoing connection (pptp, openvpn, l2tp) work fine
all pptp, l2tp incoming connection also work

After downgrade to ROS 6.7 from 6.9 back to work stable without any changes in conf

Any suggestions welcome?
Best regards
Dmitriy Krutikhin

Strange... I've done the same upgrade on my RB951 and RB751. The RB951 is the OVPN server, the other is the client. I have the tunnel running for a week now, exactly after the upgrade on both boards was done... Here's the output from the server. Maybe you have a different configuration that has issues with version 6.9...
