Is it really such a big problem to add this feature. It would be very useful. We are moving entire company to MIKROTIKS and I have directors that have mapped drives using NetBIOS names. They cannot access mapped drives due to lack of dns suffix over VPN connection.
Thanks
Is this feature not yet implemented?
Can anyone give me a good reason why not?
What about implementing DNS suffix push in OpenVPN, still not functional in latest version of RouterOS and this is a very big problem I think. We have company users which map network drives by hostnames, and now they need use entire hostname with domain suffix and that’s unacceptable and confusing! When will be this basic function supported? 
So, any new info on this ? This is exactly the problem with our VPN customers… Mikrotik can set the dns-suffix in DHCP on the lan / wlans / vlans, why not PPP ?
Use older version of mikrotik
I also have problem with pptp
Last stable is blocking
Go back to bug fix channel
Every new version something old not working.
Surprised to see that this is still (almost 8 years after the initial post!) doesn’t seem to be implemented.
Is there any news? That is a serious problem with VPN setup for me - editing connections on 500+ machines just doesn’t look right.
2x on this. I need it for a major client.
People, there is NO dns-suffix in PPP protocol.
Windows Clients obtain it via other means, like DHCP requests over PPP link, AFTER PPP link is established and operational.
It is MS specific implementation.
To make the same functionality ROS creators should rewrite lots of code, i guess, intercepting DHCP broadcasts on PPP link.
Same comes for classless static routes feature.
Here is the proof, tcpdump on fresh ppp session:
