OVPN problem.

RouterOS General
1

Hi,

I have problem with ovpn server on routeros 3.30 (RB133).
On MAC OS (client) with openvpn 2.2.1 everything is ok.
But on WINDOWNS system (client) with openvpn 2.2.1 I have resetting connection after ARP FLUSH:

Sat Mar 31 20:34:39 2012 Successful ARP Flush on interface [25] {26B1016F-F75B-4C4A-8434-19939406F5D3}
Sat Mar 31 20:34:39 2012 Connection reset, restarting [0]
Sat Mar 31 20:34:39 2012 TCP/UDP: Closing socket
Sat Mar 31 20:34:39 2012 Closing TUN/TAP interface
Sat Mar 31 20:34:39 2012 SIGUSR1[soft,connection-reset] received, process restarting
Sat Mar 31 20:34:39 2012 Restart pause, 5 second(s)

Please help me fix this problem.

Best regards

Not enough information. There are a lot of reasons for this kind of error (soft reset). Did you look into server log, not only client? Often it helps.

It was my false (add local-address to ppp secret is enough) but now I have a lot of informations:

Ok, problem is fixed = add “ip-win32 ipapi” to client config.

Thanks.
