Hi,

I have a router running 5.16 set up according the openVPN Wiki guide (http://wiki.mikrotik.com/wiki/OpenVPN)
using cacert.org and tun (ip) mode.

the openvpn gui shows this error:

Mon May 14 20:40:36 2012 TLS: Initial packet from (server ip):1194, sid=f0fc6eab 56522674
Mon May 14 20:40:36 2012 VERIFY OK: depth=1, /O=Root_CA/OU=http://www.cacert.org/CN=CA_Cert_Signin ... cacert.org
Mon May 14 20:40:36 2012 VERIFY OK: depth=0, /CN=www.*****.***
Mon May 14 20:41:36 2012 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
Mon May 14 20:41:36 2012 TLS Error: TLS handshake failed
Mon May 14 20:41:36 2012 Fatal TLS error (check_tls_errors_co), restarting

winbox log shows:
TPC connection established...
dialling...
using encoding...
terminating... -peer disconnected

What I am really unsure of is that according to the wiki:
-no new interface was added (openvpn appears automatically when I attempt to connect)
-no new dhcp server (only pool)
-didn't create nat rule because I already have: add action=masquerade chain=srcnat comment="Added by webbox" disabled=no out-interface=INET to-addresses=0.0.0.0

I am quite a noob when it comes to routeros so please advise what other info I should post. What are the next steps to take to troubleshoot?

Thank you!

I'm now using easy-rsa generated keys and get the same result on win7 with openvpn 2.2.2 as client.

The client says this:

Routerboard this:

18:20:31 ovpn,info <ovpn-0>: dialing... 
18:20:42 ovpn,info <ovpn-0>: using encoding - AES-256-CBC/SHA1

18:20:48 ovpn,info <ovpn-0>: terminating... - peer disconnected 
18:20:48 ovpn,info <ovpn-0>: disconnected

Now how can I look deeper what might be causing the problem?

Is my client conf file ok?

client

dev tun

proto tcp

remote ******** 1194


resolv-retry infinite

nobind

persist-key
persist-tun

ca ca.crt
cert certs/cleint.crt
key certs/client.key

verb 5
ping 10
cipher AES-256-CBC
auth SHA1
pull

I even tried L2TP but that didn't go any further either :/
Please advise.

UPDATE: Got L2TP running and aborted OVPN access. Thanks for taking a look.
