How to set up OpenVPN on MGTS Gpon?

Question

openvpn

Gpon home internet from MGTS.

When you connect to OpenVPN, the IP seems to change according to 2ip.ru, but, for example, you can’t access rutracker.

Is this related to the "gray" MGTS IP starting with 109.* and do you need a public IP?
It seems that they write that this is only necessary for VPNs using GRE technology, and OpenVPN is SSL ...

Or can you change the router settings?

Answer 1

External IP(public) is generally unnecessary in this scheme, because you act as a
DNS server client on your PC - what are the costs? try changing for example to cloudflare...
Most likely DNS blocking is in progress, since 2ip shows the correct IP,
show the output of the command (you need to do it in the console) tracert rutracker.org
