VPN over PPTP client not get DNS

[cherepa]

In the creator of the PPTP connection Epygi quadro 2x client gets IP adress of the server, but does not receive DNS.
Is it possible to reason in the IP routing configuration software error in the firmware

Boot loader: 5.1.18/ReleaseFirmware Version: 5.2.12/Release?

topology is :
Quadro 2x behind a router Linksis in DMZ mode forwarded to internall IP adress of Quadro.

Router IP rage is 10.0.0.1
Wan IP of Quadro is 10.0.0.149 in Dynamic DHCP mode
Lan range of Quadro is in default mode -172.30.0.1 to 172.x.x.x
Subnet of PPTP server is :192.168.0.0/24
Ip routing is set to VPN tunnel to 192.168.0.0/24
Now tunnel state is up but the test client get only IP adress 192.168.0.2 and IP default gateway 192.168.0.1
not DNS ......

Ah same issue for me, but with the vpn pptp settings by default. The client is connected with 172.31.1.3, mask : 255.255.255.255 and no dns.

I found a trick, I add the dns settings manually in the IP V4 settings. It work perfectly, but is it possible to provide dns automaticaly? I found something else too, is it correct if I add dns in the dns server settings?

Network menu> dns server settings.

I'm not very friendly with this type of configuration.
