Hi,
I am using a Miktotik router with RouterOS 6.49.7 to connect my internal network to internet.
I use the ONT and the router (as bridge) provided by the internet provider and the mikrotik is connected using a PPoE interface.
I have created PPTP, L2TP and OVPN client interfaces to implement VPNs to client companies.
Everything was working until I replaced the providers router with a newer model.
Some PPTP VPNs stopped working.
I noticed that blocked PPTP VPNs use as PPTP server pptpd on Linux. PPTP VPNs that work use Windows RRAS server or other routers.
I replaced the new providers router (used as bridge) by the old one and everything is working fine again.
Any ideas regarding this strange problem?
Can I connect the mikrotik router directly to ONT without using providers router?
Thank you,
The current version of RouterOS 6 is 6.49.10 (Long-term and Stable) so upgrading your router would be a good thing to do (it won’t necessarily fix the problem but it’s worth doing).
Obligatory “Please Don’t”: PPTP is not secure and should not be used any more. Support for it was dropped by Apple and Android some years ago and even Microsoft (the creator of PPTP) say don’t use it.
OK, now that I’ve got that out of the way, are you able to check the exact config of each of your ISP provided routers? Make a note of all of the settings on the units and compare them to see if there is anything obvious that would be causing the blocking on the new unit.
I can’t speak for your specific arrangement but I have connected a MikroTik router to an ONT and it has worked very well. You need to make sure that you have all of the required settings right (i.e.: VLAN, DHCP, PPPoE, etc.) on the WAN port otherwise the connection will fail. So, as I said above, make a note of all of the settings on the ISP provided router, configure your MikroTik WAN port to match and then plug it in and see. Keep in mind that some ISP’s lock the network connection to the router MAC address either for a set time period (like 15 minutes) or permanently until you ask to have it released (Telstra in Australia is know to have done this in the past).

Please, export and attach your current config to your post if you want help with a config issue:

Thank you MickeyT,
I have removed the provider’s router and connected Mikrotik directly to ONT. Now everything works OK.
