E-mail tool is the utility that allows to send e-mails from the router. Tool can be used to send regular configuration backups and exports to network administrator.
Email tool uses only plain authentication and tls encryption. Other methods are not supported.

All data that you need is here:

Server:   74.125.136.108 [smtp.gmail.com] <- you can't use hostname
Port:     587
From:     <your name> <- nice name
User:     <gmail username> <- without @gmail.com
Password: <gmail password>

Configuring this tool is very simple, all you need to do is fill your data as shown in the picture

or you can do this in one step from the terminal:

/tool e-mail set address=74.125.136.108 from="<your name>" password=<gmail password> port=587 start-tls=yes user=<gmail username>

This is all you need to do… next time I will write some usage example. If you have some your example, you can leave it in a comment ;)

Last time I wrote how to configure a PPTP VPN Server on Mikrotik RouterOS

Today I will show you how to configure a PPTP VPN Client on Mikrotik RouterOS.

Before we start I will try to explain what I want to do…

My home network:

192.168.1.0/24 - Private
192.168.2.0/24 - Public

Remote location:

192.168.3.0/24

I would like to establish a VPN connection to the remote location on my Mikrotik router and allow computers (only!) from my private subnet to access computers on the remote location.

This tutorial will explain you how I did this. Here is a simple step by step tutorial with images and all information that you need to get PPTP VPN Client working…

Step 1: Create PPTP Client

Noting special on this step, so I think that the image is enough :)

Step 2: Configure PPTP Client

After you created the PPTP Client you will need to enter some basic information:

1. VPN server hostname or IP
2. VPN username and password

then you need a name for the client…

If you enter the correct information you are already connected to the VPN server

You can now double-click on pptp-client and see the status

Note

With the current configuration I can ping a remote computer from my Mikrotik:

[admin@MikroTik] > ping address=192.168.3.2 src-address=192.168.3.101 count=3 
HOST                                     SIZE TTL TIME  STATUS                                  
192.168.3.2                                56 127 42ms 
192.168.3.2                                56 127 44ms 
192.168.3.2                                56 127 41ms 
    sent=3 received=3 packet-loss=0% min-rtt=41ms avg-rtt=42ms max-rtt=44ms

but I can’t ping the same computer from any other location (other computers connected to my Mikrotik…

C:\Users\User>ping 192.168.3.2

Pinging 192.168.3.2 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.

Ping statistics for 192.168.3.2:
    Packets: Sent = 3, Received = 0, Lost = 3 (100% loss)

to resolve this we need to add a NAT rule and one more route

Step 3: NAT configuration

[admin@MikroTik] > /ip firewall nat print
...

 1    ;;; pptp-client masquerade
      chain=srcnat action=masquerade src-address=192.168.1.2-192.168.1.254 
      out-interface=pptp-client log=no log-prefix="" 

...

src-address is used to allow only computers from my private subnet

In simple words… With this we allowed other computers to use VPN client interface.

Step 4: Add new route

route #4 is automatically added with pptp-client.
We need to add route #3…
Again… in simple words… With this route we route all request from 192.168.1.1 (router IP for private subnet) to remote subnet

[admin@MikroTik] > /ip route print 
 #      DST-ADDRESS        PREF-SRC        GATEWAY            DISTANCE
 ...
 3 A S  192.168.3.0/24     192.168.1.1     pptp-client               1
 4 ADC  192.168.3.100/32   192.168.3.101   pptp-client               0
 ...

Step 5: Finish

If you did all right, you now have access to the remote subnet from your private subnet.

A quick test…

Before I started to wrote this post, I thought that would be nice to say some word about PPTP VPN and Mikrotik RouterOS, but then I realized that if you are reading this, there is no need to explain what is PPTP VPN server or Mikrotik RouterOS.

Here is a simple step by step tutorial with images and all information that you need to get a fully working PPTP VPN server…

Step 1: create VPN pool

IP pools are used to define range of IP addresses that will be used for your PPTP VPN server

[admin@MikroTik] > /ip pool print
 NAME      RANGES
 VPN-pool  192.168.1.101-192.168.1.110

Step 2: create a VPN user

In this step you will create a user that can connect to your VPN Server. In this example only one user is created, but you can add as many user as you need…

[admin@MikroTik] > /ppp secret print
 # NAME SERVICE CALLER-ID PASSWORD PROFILE     REMOTE-ADDRESS
 0 ppp1 pptp    ppp1      ****     VPN-profile

Step 3: create a VPN profile

From wiki.mikrotik.com

PPP profiles are used to define default values for user access records stored under /ppp secret submenu. Settings in /ppp secret User Database override corresponding /ppp profile settings except that single IP addresses always take precedence over IP pools when specified as local-address or remote-address parameters.

[admin@MikroTik] > /ppp profile print
 1    name="VPN-profile" local-address=192.168.1.1 remote-address=VPN-pool bridge=br1 use-mpls=default
      use-compression=default use-vj-compression=default use-encryption=yes only-one=default
      change-tcp-mss=yes address-list="" dns-server=8.8.8.8,8.8.4.4

Step 4: Create PPTP Server Binding (Optional)

This step is optional, because your VPN server will work even if you skip this.

In this step you bind user ppp1 to interface pptp-in1. This is very useful if you need to create firewall rules for a specific user.

Step 5: Enable VPN Server

In this step we just need to enable our PPTP server and set default profile…

[admin@MikroTik] > /interface pptp-server server print
           enabled: yes
           max-mtu: 1450
           max-mru: 1450
              mrru: 1600
    authentication: mschap1,mschap2
 keepalive-timeout: 30
   default-profile: VPN-profile

Step 6: Configure bridge (Optional)

Like step 4, even this step is optional. This step is the main reason that I’m writing this tutorial, so it deserves a few word :)

If you skip this step, you will be able to connect to your VPN server, you will have the same public IP as your VPN server, but you will not see any other devices connected on this subnet. If this is OK for you, you don’t need to do anything else.

If you want to see other devices in your subnet, you must change ARP mode for your Bridge. For more details about ARP modes go to mikrotik documentation

[admin@MikroTik] > /interface bridge print
Flags: X - disabled, R - running
  0    R name="br1" mtu=1500 l2mtu=1598 arp=proxy-arp mac-address=4C:5E:0C:21:A4:85 protocol-mode=rstp
         priority=0x8000 auto-mac=no admin-mac=4C:5E:0C:21:A4:85 max-message-age=20s forward-delay=15s
         transmit-hold-count=6 ageing-time=5m

Step 7: Finish

If you did all right, you now have a working PPTP VPN server.

Important: Don’t forget to open port 1723 (tcp) in your firewall settings:

/ip firewall filter add chain=input comment="PPTP VPN" dst-port=1723 protocol=tcp
