Configuring OpenVPN

technog0d · Tue Aug 14, 2007 5:53 pm

Can someone please post a how-to on configuring th OpenVPN server on routeros and then the client side. Specifically, does the routeros generate the certificate? The whole process would be nice.

Thanks in advance...

Wed Aug 15, 2007 1:25 pm

RouterOS router does not generate the certificate, you have to use your own certificate and import it at /certificate and it should be decrypted by 'certificate decrypt'.

Client mode has teh following configuration options,
("interface ovpn-client"):
connect-to:
port:
user:
password:
certificate: If server is asking for private certificate.
auth: HMAC alghoritm to use.
cipher: make sure it is matching the server side configuration.
mode: configuration for encapsulation options, also it should match server side configuration.
mac-address: interface mac-address, ja mode=ethernet
profile:
add-default-route:

Note, that currently TCP tunnel is supported only.

technog0d · Wed Aug 15, 2007 4:15 pm

i am really more interested in the server side for openvpn on Routeros. It does not seem like there is a provision for user auth on the server side. How do you make sure that the openvpn server is only allowing specified users. Is the certificate the only method of authorization?

Thanks Again...

Wed Aug 15, 2007 4:30 pm

As far as I know you may specify clients at 'ppp profile', in the same way as for PPTP, L2TP.

OpenVPN server options ("interface ovpn-server server"):
enabled:
port:
mode:
netmask:
mac-address: server interface mac-address
max-mtu:
keepalive-timeout:
default-profile: ppp profile
certificate: server certificate
require-client-certificate: if certificate should be used on client
auth:
cipher:

Anybody got this Up and running?
When I connect to Router OS 3.0 rc4 in server mode I receive this error:

Tue Sep 04 16:43:29 2007 us=462832 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
Tue Sep 04 16:43:29 2007 us=463073 TLS Error: TLS handshake failed

No need to tell you that network connectivity is not the Problem.
For me the main problem is that I actually have no clue how to configure
the server side.

Is there some type of docu out there?

Or at least has anybody out there a working set of Router OS Server and PC Client
Windows or Linux should not be the issue since the config is the same.

Thanks
Ekkehard

Wed Sep 05, 2007 4:11 pm

Ekkehard,
post your configuration here from Open-VPN server,
what OS is used on the client side ?

burkon · Thu Sep 06, 2007 9:56 am

Ekkehard,
post your configuration here from Open-VPN server,
what OS is used on the client side ?

Hope that is all the relevant stuff.
Client OS is Windows 2000 with OpenVPN 2.0.7

Thanks

I was looking at this and am getting similar errors. I've tried to set things up as Ekkehard and see exact the same issue. Release is Router 3.0rc4.

Could anyone post a working server setup (Mikrotik being the server ?). Might shed a bit more light into things.

In my case the client is Debian and OpenVPN 2.09

It seems to be that MT needs TLS, otherwise it will kill the connection after 1 minute.
You have to setup the openvpn at the linux-side with tls.
It seems to be that MT currently only supports pkcs12 certificates for openvpn.

Simple howto (Debian as Server, MT as client):
# copy easy-rsa to /etc/openvpn:
cp /usr/share/doc/openvpn/examples/easy-rsa /etc/openvpn
cd /etc/openvpn/easy-rsa
# edit the file vars:
vi vars
# import vars and build-ca
. ./vars
./clean-all
./build-ca # set "OpenVPN-CA" as common name (or anything else you want as CN)
./build-key-server # set "server" as common name (or anything else you want as CN)
./build-dh
# build cert for client1 (MT):
./build-cert-pkcs12 client1 # set "client1" as common name (or anything else you want as CN)
### copy keys/client1.* to MT and import the client1.p12

add this to your openvpn config at debian:
cipher BF-CBC
auth SHA1
tls-server
ca /etc/openvpn/easy-rsa/keys/ca.crt
cert /etc/openvpn/easy-rsa/keys/server.crt
key /etc/openvpn/easy-rsa/keys/server.key # This file should be kept secret
dh /etc/openvpn/easy-rsa/keys/dh1024.pem
proto tcp-server # MT currently only supports tcp

# MT needs that openvpn assign ip addresses...
server 192.168.10.0 255.255.255.0

## At MT set the same cipher and auth as above and set the cert to the first cert
## which was created after import (the cert with the flags "KR" at /certificates)

Best regards,
Timo Schlegel

I'm testing OpenVPN client on a RB133C with v3.0rc6. I know it's a beta, and it's first time I try it. This version is extremely slow, sure it's a bug. It lasts a lot to boot and establish the OpenVPN connection. Each time I enable/disable OpenVPN client, or try to import a certificate, or whatever, RouterOS crash.

As is the first time I try it, and gone stright forward to try OpenVPN, don't know if this issue comes from OpenVPN or it's "normal" for this Beta running on RB133C.

pingus · Tue Oct 16, 2007 5:06 pm

Did it one the other way around, MT as server and linux as client?

I can open a connection but I can not ping MT and the client doesn't receive an IP from the router.

No, I've just tested MK as client and Linux-box as server. and it works.

This is good for you but doesn't helps me

Here is my linux config:

  group nogroup

  comp-lzo

  ping 15
  ping-restart 45
  ping-timer-rem

Hopefully I added all relevant config.

acidbits · Wed Oct 17, 2007 8:42 pm

Maybe you need to add this to you linux config:

cipher BF-CBC
auth SHA1

I don't have any rboard at home to test right now, sorry.

pingus · Thu Oct 25, 2007 12:03 pm

How do I have to configure the firewall to get MT as OpenVPN server running?

pingus · Mon Oct 29, 2007 12:38 pm

As I could test with 2 RouterOS the firewall isn't a problem. Two RouterOS are connecting well.

Is it possible that OpenVPN Server on RouterOS is waiting for a username? Can I send a username from OpenVPN Client running on Linux?

pingus · Mon Oct 29, 2007 2:50 pm

Finally I got OpenVPN working to the point where I have a registred connection. I also get an IP address. Now I have to find out how to ping across the two routers.

Here are my linux client settings:

dev tun0
  proto tcp-client

  remote example.com 1194

  ca root.pem
  cert client.cert
  key  client.key

  tls-client
  tls-remote example.com

  port 1194

  user nobody
  group nogroup

  comp-lzo

  ping 15
  ping-restart 45
  ping-timer-rem
  persist-tun
  persist-key

  mute-replay-warnings

  verb 3

  cipher AES-256-CBC
  auth SHA1
  pull

  auth-user-pass auth.conf

inside auth.conf you have to enter the username on the first line and on the second line the password of the user you want to login.

I hope this will help someone else.

Mon Oct 29, 2007 3:20 pm

you can make a wiki article on this, if you are sure it works every time

also write the RouterOS config there. go here:

http://wiki.mikrotik.com/wiki/OpenVPN

and hit the Edit button (after logging in)

pingus · Mon Oct 29, 2007 3:52 pm

Sure, I will do this as soon as I fixed ping issues.

marlow · Fri Nov 09, 2007 12:22 am

I've tried to get OpenVPN going proper for a while now. RouterOS client to Linux Server no problem. But RouterOS client to RouterOS server always ends up with:

00:08:57 ovpn,info TCP connection established from 192.168.0.2
00:08:57 ovpn,info <ovpn-0>: dialing...
00:08:58 ovpn,info <ovpn-0>: terminating... - TLS handshake failed
00:08:58 ovpn,info <ovpn-0>: disconnected

The same RouterOS client has no problems connecting to a Linux OpenVPN server without configuration change.

I then tried to follow the wiki, that pingus has put together. Still NO GO. Both boxes are now 3.0rc9, still with those issues (were 3.0rc5 before).

Anyhow, I've send supout.rif's of both boxes to support, let's see, what they come up with.

/Martin

marlow · Sun Nov 11, 2007 2:29 am

require-client-certificate was the problem. That doesn't seem to work yet. Once set to "no", both Linux and RouterOS clients will connect.

Bugger. Anyhow, I've updated the Wiki article at http://wiki.mikrotik.com/wiki/OpenVPN, so it should cover all angles and hopefully also the potholes now.

thavinci · Fri May 02, 2008 1:19 pm

acidbits : How do you get openvpn to work with usernames & passwords?
Currently i have a working solution that lets clients connect with their certificates only.

However it seems MT doesnt allow you to NOT specify a username!

Hi!
I have the Linux server oVPN working fine. Linux and Windows clients are connecting succesfully. I'm not able to connect with the ROS client. Please cen you give me a short walk-through on how to make it work? I know there are more ppl that would be happy to read it.

Thank you for help.

thavinci · Tue Jul 07, 2009 12:11 pm

I still cannot get openvpn client connecting to a unix/linux openvpn server.

It seems i still cannot create a client without specifying a user-name!
I don't use user names/passwords, only certificates.

Chupaka · Tue Jul 07, 2009 2:34 pm

yesss, only username+password, no certificates

Tue Jul 07, 2009 2:58 pm

or
username+password+certificate

thavinci · Tue Jul 07, 2009 3:08 pm

Unfortunately that would require a redo of the server and loss of current clients....

NAB · Sun Oct 04, 2009 11:34 pm

Anyhow, I've updated the Wiki article at http://wiki.mikrotik.com/wiki/OpenVPN, so it should cover all angles and hopefully also the potholes now.

These updates are now out of date and I have corrected one obvious mistake I found. However...

The command '/interface ovpn-server server [name] cipher=none' is invalid as on the server, 'none' is not a valid option for 'cipher' in ROS 3.29 or 3.30. It is a valid option on the client though, so I assume that this is a bug and have e-mailed support accordingly.

risipetillo · Mon Mar 22, 2010 5:25 am

I've followed the WIKI and I'm having similar problems when I try to get my ROS OVPN Client (v3.30) to speak to my ROS OVPN Server (v3.30).

I get the following error: terminating ... TLS Handshake Failed

I don't understand where I'm going wrong. PLEASE HELP !!!

Kindly see my configuration below:

roadracer96 · Tue Mar 23, 2010 1:34 am

Default profile on client side is no encryption. You are requiring encryption on the server side. Cant negotiate encryption if one side isnt configured to use it.

Thatd be my guess..

risipetillo · Tue Mar 23, 2010 7:12 pm

As far as I understand the "cipher= xxxx" is where we would enable encryption or not.

I have encryption on both the Server and Client side:

roadracer96 · Wed Mar 24, 2010 5:47 am

Yeah, I just tried it. It doesnt matter for OVPN.

Did you try putting a cert in on the server? I never have run w/o a cert on the server before.

Wed Mar 24, 2010 8:08 am

On a server you need CA and "server" certificates, otherwise OVPN will not work.

risipetillo · Thu Mar 25, 2010 4:47 pm

I've put a cert on the server, and on the client and still nothing.

Can someone show me their working config, I don't know what I'm doing wrong here.

Additionally, I have an L2TP server running on the same box without any issues: clients are able to connect via L2TP without a problem. Just having a problem with OpenVPN.

PLEASE HELP, I'm getting my butt handed to me by this Mikrotik box ... lol

roadracer96 · Thu Mar 25, 2010 6:26 pm

Do you have a cert installed and assigned to the openvpn server AND the CA cert that signed it?

Following your example it worked !!!!

I had to reboot my RB450 (not too sure why) before it started working.

I now have two clients configured for it.

Thanks a million.

For a second there I was loosing hope in this forum ....

Thanks again.

I had to reboot my RouterOS v5.2 x86 before the MikroTik OpenVPN server worked with my RHEL v6 OpenVPN client.

theprism · Sun Jan 27, 2013 10:49 pm

Hello,

Does anyone knows how to generate the certificates without having a real domain and without having a root/admin/etc. mail (e.g. root@bla-bla.bla.com)?

Thank you,
Alex C.

Pada · Sun Jan 27, 2013 10:58 pm

Have a look at OpenVPN's Easy RSA stuff: http://openvpn.net/index.php/open-sourc ... ement.html

Alternatively you can create certificates with OpenSSL command line application.

metalcated · Thu May 02, 2013 5:42 pm

I followed the Wiki page and mostly feel I have VPN working minus being able to actually connect outside of my network. I am new to MikroTik and RouterOS but have background with similar setup's.

When I try to connect .. client -> server -->

Hi !

Just a small question (not to complicate that stuff at all):

Did someone got openVPN-Server running in conjunction with PPPoE-Client ?

(Here´s my posting about that: http://forum.mikrotik.com/viewtopic.php?f=1&t=72072)

Thanks
