MIKROTIK : SITE-TO-SITE PPTP

Site-to-Site PPTP

The following is an example of connecting two Intranets using PPTP tunnel over the Internet.

Consider following setup

Office and Home routers are connected to internet through ether1, workstations and laptops are connected toether2. Both local networks are routed through pptp client, thus they are not in the same broadcast domain. If both networks should be in the same broadcast domain then you need to use BCP and bridge pptp tunnel with local interface.

First step is to create a user

[admin@RemoteOffice] /ppp secret> add name=Home service=pptp password=123
local-address=172.16.1.1 remote-address=172.16.1.2 routes="10.1.202.0/24 172.16.1.2 1"
[admin@RemoteOffice] /ppp secret> print detail
Flags: X - disabled
  0   name="Home" service=pptp caller-id="" password="123" profile=default
      local-address=172.16.1.1 remote-address=172.16.1.2 routes=="10.1.201.0/24 172.16.1.1 1"

[admin@RemoteOffice] /ppp secret>

Notice that we set up pptp to add route whenever client connects. If this option is not set, then you will need static routing configuration on the server to route traffic between sites through pptp tunnel.

Next step is to enable pptp server on the office router and configure pptp client on the Home router.

[admin@RemoteOffice] /interface pptp-server server> set enabled=yes
[admin@RemoteOffice] /interface pptp-server server> print
            enabled: yes
            max-mtu: 1460
            max-mru: 1460
               mrru: disabled
     authentication: mschap2
  keepalive-timeout: 30
    default-profile: default
[admin@RemoteOffice] /interface pptp-server server>

[admin@Home] /interface pptp-client> add user=Home password=123 connect-to=192.168.80.1 disabled=no
[admin@Home] /interface pptp-client> print
Flags: X - disabled, R - running
 0    name="pptp-out1" max-mtu=1460 max-mru=1460 mrru=disabled connect-to=192.168.80.1 user="Home" 
       password="123" profile=default-encryption add-default-route=no dial-on-demand=no 
       allow=pap,chap,mschap1,mschap2
[admin@Home] /interface pptp-client>

Now we need to add route to reach local network behind Home router

[admin@RemoteOffice] /ip route> add dst-address=10.1.202.0/24 gateway=172.16.1.2

Now after tunnel is established and routes are set, you should be able to ping remote network.

How to configure Windows XP to manage Wireless Network Connections

This article will describe how to configure Windows XP to manage your computer’s wireless connection. Many computer manufacturers create their own wireless networking software utilities and install it on their machines from the factory. If you are having trouble connecting, it can be easier to troubleshoot the issue if you allow Windows to manage your connections. Since there are so many different, manufacturer-specific wireless interfaces, User Support Services does not provide support for any other utilities except the standard Windows interface.
