Mikrotik as OpenVPN client issue

RouterOS General
1

Hi,

I have an issue with HEX S after upgrading its firmware to 7.2.1 version. I setup an OpenVPN client on this router, and before the upgrade it worked pretty well and stable. Now the connection is not being established. Router sends a push request, OpenVPN server responds, and the connection resets from the router side.

Here is the extract from OpenVPN server logs:

PUSH: Received control message: ‘PUSH_REQUEST’
SENT CONTROL [mikrotik]: ‘PUSH_REPLY,route-gateway 10.8.0.1,topology subnet,ping 10,ping-restart 120,ifconfig 10.8.0.20 255.255.255.0’ (status=1)
Connection reset, restarting [0]
SIGUSR1[soft,connection-reset] received, client-instance restarting
TCP/UDP: Closing socket

All other vpn clients work well with this OpenVPN server. The server runs on Ubuntu, its version is 2.4.7.

Could you please advise me how to fix the issue?

I think it is the very same issue as we are discussing here: http://forum.mikrotik.com/t/v7-2-openvpn/157153/14

Thank you for the link provided. This is the same problem indeed. I’d downgraded firmware to the version 7.1.5 AS_A_TEMPORARY_WORKAROUND and OpenVPN client on hEX S started working again. Will be waiting for the permanent solution from Mikrotik Support Team. I hope they will fix the issue soon.
