How to set up a pptp connection through a router?

Question

Network administration

Good afternoon!
I ran into an interesting problem for myself.
I'm trying to set up a connection to my PPTP server located on the VPS on the DIR300 router.
And all to no avail.
I can't figure out what the problem is. What has been done on my end. A pptp server is configured on the server side.
From under Windows there is a connection. So the server is running successfully.
But the router does not want to connect to any. I have already tried both on the DD-WRT firmware and on my own now I'm tinkering. Zero result.
If you use an account from hideme.ru, then the router connects and everything is fine. But there is no connection to my server.
I have completely disabled iptables on the server side. At the time of setup in order to exclude the firewall from the problem. But it's probably not the problem.
Where else to dig?
Router model Dlink Dir 300.

Answer 1

Is the latest firmware on the router?
Did you mess with the encryption?

Answer 2

I want to solve the same problem as the topikstarter, but my connection goes through. Although the connection indicator on the router interface is not green, I can ping both the IP of the PPTP server located on the remote VPS server and the address that the router gave out. Of course, the response time from the router is many times less than the response time from the server. So everything is working correctly.
How to make it so that for all computers in LAN traffic goes through this tunnel? After all, I cannot check the "default route" checkbox on the tunnel, since it simply does not exist, it is only opposite the WAN in the same table of the router interface.
I believe that the solution to the problem may be associated with prescribing routes on client cars. But if I change the default route, then the packets will stop going to the router, and the addresses inside the tunnel are from a different subnet. Or do you need to register them as in the router's LAN, then the router itself will be able to sort out where to send packets with a new default route on the locale?
PS. He asked, he answered =)
After digging a little more in the router settings, I found in another section of the menu the ability to register additional routes. And when you specify the internal address of the PPTP server there, all traffic from clients behind the router went through the tunnel.
