MikroTik

Posted: **Sat May 24, 2014 6:58 pm**

Hi

I'm looking for a good and secure VPN connection from my android mobile phone
to my mikrotik router (MikroTik RouterOS version 6.13)

If possible with a good manual/documentiation so that it's easy to
create for a beginner.

Thanks for any help

Regards

Im also looking at implementing a simple VPN for ipad and android access.

I have followed a tutorial on PPTP Server but my windows client always gives em an 800 Error? I Will be watching out for a link or something.

L2tp + ipsec -> sounds good

but how can I configure that ?

Thanks

on my Android I have only following settings:

- PPTP
- L2TP/IPSEC PSK
- L2TP/IPSEC RSA
- IPSec Xauth PSK
- IPSec Xauth RSA
- IPSec Hybrid RSA

Is there any reason why PPtP with MPPE-128 and MS-CHAP V2 would not be sufficient?
Cracking a 128bit encryption is not trivial. The biggest risk is yourself giving away your username and password.
And it is supported by a lot of devices, including Windows, Android and iOS.

LE: Ok. It seems that MS-CHAP2 can be cracked...
https://www.cloudcracker.com/blog/2012/ ... s-chap-v2/
On a 48 core FPGA dedicated device and a network capture it takes half a day to a day, but never the less.

I have setup a PPTP server, but I am having no luck connecting to it from my phone.

I enabled PPTP Server, Added A PPTP Binding server , added 2 users under secrets, configured a profile for me using a ip pool.

I can connect on my windows 8 desktop, but for some reason my windows 8 laptop and my android cant connect to it?

When I try connect I see this in the log on the mikrotik:

    pptp, info       TCP connection established from 41.208.229.224

But then thats it, the client times out trying to connect.

When I connect on my desktop, which for some reason seems to work, the following is in the log.

    pptp, info           TCP connection established from 41.208.229.224
    pptp,ppp,info      test loggen in, 10.0.0.10
    pptp,ppp,info      <pptp-Test> authenticated
    pptp,ppp,info      <pptp-Test> using encoding - MPPE128 stateless
    pptp,ppp,info      <pptp-Test> Connected

What could be causing this error?
Is there a minimum password or user length?

I have done some debugging and found that if i try connect to the vpn on my android via the wireless, it doesnt connect, but I still see the tcp connection on the mikrotik,

but if i disable wireless and connect to the vpn via gsm. it seems to connect? Why would this be? The vpn server is a remote mikrotik, and im using dyndns.org to point to it.

Here in my country 3g carriers are blocking pptp ports.
Because of that for mobile vpn i am using l2tp+ipsec

Hi Guys,

I installed ROS 6.13 as a VM on my ESXi running version 5.5. I tried to get PPTP to work with my iPhone 5 for days without success - then I found this post:

http://forum.mikrotik.com/viewtopic.php?f=15&t=78280

Turns out ESXi 5.5 had a bug that would drop PPTP traffic. After upgrading to 5.5 U1, I was able to connect.

I wouldn't waste your time setting up a PPTP connection as it's been hacked so badly it's considered nearly worthless. In my case the entire reason I'm switching routers to MikroTik is to get away from PPTP. Now if OpenVPN wasn't so darned confusing! And the Wiki is useless as it's an old version and not clear at all.

is there any manual for L2tp + ipsec ?

My Android Mobile can only:
- PPTP
- L2TP/IPSEC PSK
- L2TP/IPSEC RSA
- IPSec Xauth PSK
- IPSec Xauth RSA
- IPSec Hybrid RSA

I do not like to use PPTP !

Thanks

got a similar issue connecting to my L2TP/IPsec server on my RB951 (ROSv6.24) via 3G / cellular (other VPNs thou work)
i tested to an other L2TP/IPsec VPN of a friend of mine ... success (via 3G)

i see that my iphone6 connects to the router to ports 500 and 4500

in the log i see:

when i connect my iPhone6 to a WiFi (does not matter which one) there is no problem with the L2TP/IPsec connection from my iPh6 to my RB951

what can i do to

I'm sorry but as you can tell from all the messages prior to your post, no one seems to be able to make this work and there has been no response from support on this in months. You can post all the questions you like, but there's been no help for anyone here. Worst router ever. Worst support ever.

UPDATE:
what i was able to do is, to set up a VPN connection to the same router with the same user via PPTP!

when i try to set up the connection via L2TP/IPsec ... no luck...

I'm having exactly the same problem, works fine over Wi-Fi but will not work over Cellular. I've tried a Nexus 5 with Lollipop and an iPhone 5 with iOS 8.1.3, I've tried a T-Moible UK and Three UK SIM Card and neither will work.

Can't figure out where the issue lies.

Can't figure out where the issue lies.

i'm even seeing the connection (phase 1) is established via port 500, 4500 and 1701 from my mobile (FROM my mobile IP address) when i look it up in [ ip > firewall > connections ]
in the LOG i see something like "11:58:34 l2tp,info first L2TP UDP packet received from 213.162.68.xxx"

which cellular provider do you use? and are you getting a official WAN IP on your mobile via your 3G/4G mobile data connection?

I have an L2TP VPN connection on a Verizon droid to an RB751 running 6.32.3.

Posted: **Wed Nov 11, 2015 11:01 am**

I have an L2TP VPN connection on a Verizon droid to an RB751 running 6.32.3.

so then i assume Verizon is permitting direct IP communication from your mobile device to your router (vpn server)

i do not have that advantage here in austria (telering / t-mobile)
if i were with H3G (drei.at) i could activate "Open Internet" and then it works flawlessly.

BUT

i found a better solution for VPN .... OPEN VPN
works on GSM/UMTS/3G/LTE and WiFi with mi iPhone6 ... bit more administrative work at the beginning (self-signed cert, trail-and-error implementation

and key distribution to end-devices) but when it's configured ... works like a charm

NOTE: RouterOS still only supports TCP OVPN

Posted: **Wed Nov 11, 2015 9:50 pm**

I looked at open VPN but couldn't figure out the cert process, looks like you stuck it out.

Posted: **Sun Dec 13, 2015 4:00 am**

Here you can find step by step instructions to get VPN service on your Android phone http://www.vpnfaqs.com/2015/12/how-to-u ... oid-phone/ yoy can also use the same VPN account on your ipad and at the same connection time within encrypted tunnel ensures security and online privacy.

Posted: **Wed Dec 16, 2015 5:11 pm**

I looked at open VPN but couldn't figure out the cert process, looks like you stuck it out.

i used easy-rsa (with pkitool) which is included in the OpenVPN Tunnelblick Mac OS X suite

in terminal:

nano vars
source vars
./clean-all
./pkitool --initca
./pkitool --pass --server openVPN
./pkitool --pass client
KEY_CN=OpenVPN-Client-02 ./pkitool --pass client02
KEY_CN=OpenVPN-Client-03 ./pkitool --pass client03

here a short overview of the usage of EASY-RSA:

Creating Certificates with Easy-RSA
Easy-RSA is part of OpenVPN package at [[1]]. As of OpenVPN version 2.1 the usage is as follows:

Initialisation on Linux:

cd easy-rsa
less README
vi vars
source vars
./clean-all

=========================================================================================

Create CA (Certificate Authority, required to sign client and server certificates)

./pkitool --initca

=========================================================================================
Create Server Certificate

./pkitool --pass --server RB450

=========================================================================================

Convert Server private key to .pem format

openssl rsa -in keys/RB450.key -out keys/RB450.pem

=========================================================================================
Create Client Certificate

./pkitool --pass client1

=========================================================================================

Convert Client private key to .pem format

openssl rsa -in keys/client1.key -out keys/client1.pem

###======================================================================================

### routerboard specific ###

Usage
Referring to easy-rsa example above upload following files via sftp to RouterBoard

RB450.crt
RB450.pem
ca.crt

!! Do not upload your private ca.key !!! Now import the certificate and then its key !!

/certificate
import file=RB450.crt
import file=RB450.pem
import file=ca.crt

To the clients upload

ca.crt
client1.crt
client1.pem

And import the keys:

/certificate
import file=client1.crt
import file=client1.pem
import file=ca.crt

###======================================================================================

after that configure the OpenVPN server on the routerboard with the server certificate for which you also uploaded the server-key! (NOT the ca.crt)

VPN working with iOS client, windows client, mac osx client and also from Routerboard <=> Routerboard via OpenVPN

send-initial-contact=yes nat-traversal=yes hash-algorithm=sha1 enc-algorithm=3des,aes-256

On Android, create a L2TP/IPSec PSK VPN.
Add the address of the VPN server and the pre-shared IPSec secret key (SECRETKEY). Don't enter a secret for L2TP or a user for IPSec.

Hi, I just published a howto on my blog page about how to set up a PPTP server compatible with Android. I'm using routerOS 6.34.3 and Android 5 and 6.
http://oriolrius.cat/blog/2016/07/27/mi ... r-android/
I hope it's being useful.

Can just add one hopefully useful tip. In case if client is Android device, it seems not all IPSec authentication algorithms are supported.

In IPSec proposal settings can not use sha256 or sha512 as Auth. Algorithm, Android fails to connect if those are used. Sha1 works fine

Not sure if same applies to all device models and versions of Android, but that was my experience on Sony Xperia X, Android verion 7.1.1. RouterOS v.6.38.5

Posted: **Tue Apr 18, 2017 3:16 pm**

Thank you! I was fighting L2TP/IPsec PSK on Android and indeed it turns out it is due to the SHA256 which
was enabled in Proposals and does not work on Android. It is OK on most other platforms.

Posted: **Tue Apr 18, 2017 5:43 pm**

so what do we do to work on android.

Posted: **Tue Apr 18, 2017 5:51 pm**

It works in the default config, the problems only start when you enable those super duper hashing and encryption methods that nobody needs yet are "recommended by the experts".

Posted: **Mon Nov 06, 2017 10:43 am**

Hi,
Was trying L2TP/IPSec PSK it works fine with PCs but nothing with android and iOS ?
I'm using routerOS 6.36.1 ?

any workaround ?

Hi pe1chl,
was reading your post regarding the SHA256 on Proposals but I'm using sha1 and still no success to make it work, getting Unsuccessful when try to connect to VPN through the Android !

Posted: **Tue Nov 07, 2017 10:26 am**

It works fine for me with Android. But you should leave the phase1 settings at default or else it will fail.
