title: Mikrotik routing between networks via l2tp
body: <p>I have 2 Mikrotik routers:<br></p>
  <pre><code>Home(static WAN IP):
      LAN - 192.168.30.1/24
      VPN IP - 192.168.146.1
  Office(Cloud):
      LAN - 192.168.20.1/24
      VPN IP - 192.168.146.2
  </code></pre>
  <p>Configured L2TP\IPSec server on my home router with default-encryption profile and connected to it from office router.</p>
  <pre><code>/ppp secret add local-address=192.168.146.1 name=office password=qwerty profile=default-encryption remote-address=192.168.146.2 service=l2tp
  </code></pre>
  <p>Routers were connected successfully and can ping each other, now i have 2 questions:<br>
  1)Is this ok that client always send 1 times of 1 bytes message to server through 4500 port?<br>
  2)How can allow access to office network from home pc?<br>
  For now i just configured two routes:<br>
  Home router:</p>
  <pre><code>/ip route add distance=1 dst-address=192.168.20.1/24 gateway=192.168.146.2 pref-src=192.168.30.1
  </code></pre>
  <p>Office router:</p>
  <pre><code>/ip route add distance=1 dst-address=192.168.30.1/24 gateway=192.168.146.1 pref-src=192.168.20.1
  </code></pre>
  <p>And this doesn't work.
  Also i have another local area in office router - 192.168.46.1/24
  Is there any way that i can also access this addresses from my home pc?</p>
