PPTP (VPN Client) routing confusion

I didn’t want to get to this point, but I’ve been attempting to understand what I’m doing wrong for weeks and just can’t figure it out.

First off, I have very basic knowledge of MikroTik compared to most of you on here, so I’m sure I will get a resolution quick, since it is probably simple.

  1. This is for a remote camera site through a Mikrotik board RB411U with a cellular modem card in it. (usbx port).
  2. We need the cameras to be able to transfer photos to a server behind an EdgeRouter.
  3. I have it working to a state that I can ping another device at the EdgeRouter from the Mikrotik, but will not route through the Mikrotik.

Working:

  • The PPP Client is working great and gets a public no problem
  • I can ping the EdgeRouter (192.168.1.1) from the Mikrotik (192.168.1.201) no problem
  • My cameras get a Natted ip of 172.16.11.x IP, and have no problem communicating with the internet (google.com for example)
  • I can ping the Mikrotik (192.168.1.201) from the EdgeRouter (192.168.1.1)

Not Working:

  • I can’t communicate with any of the 192.168.1.x IP’s (including the 192.168.1.201) from behind the Mikrotik
  • It seems all traffic from behind the Mikrotik (VPN Client) doesn’t use the VPN connection and communicates all traffic throught the PPP connection.

I attempted to add a bridge bridging the PPTP port to the Ether1 port, but the PPTP port does not show up in the list of available ports when creating a bridge. (I’ve done this on other Mikrotiks trying to bridge ports within).

Interfaces: ether1, ppp-out1, pptp-out1
NAT: srcnat, 172.16.11.0/24, masquerade
Mangle1: Change MSS, In Interface pptp-out1
Mangle2: Change MSS, out interface pptp-out1
Route List: 3 DAC’s ppp-out1(public ip), pptp-out1(192.168.1.201), ether1(172.16.11.1)

It seems that it is 90% there, I’m just missing that last 10% of the config.
I am basically modifying previous settings that were done by our previous IT person who is no longer employed here.

Tell me what further information will be helpful.

I’m really just assuming there is something simple I’m missing or not understanding.

Also, the overall intention is to have remote cameras be able to interface with one master NAS when motion is detected.

  • Mikrotiks have Sim Cards as connection to internet
  • QNAP/NAS may be behind a EdgeRouter or Mikrotik router that has the VPN set up

Is there a better way to do it than what I’m doing?
