After update to Fedora 25 one of my PPTP connections strangely works. Remote net is not available.

It is connected, successfully get remote net IP address. While connected nothing is available in remote net, but internet works fine. After a few minutes connection breaks by itself.

I've noticed strange thing, while pptp connection is on there are too much TX packets transferred:

        inet  netmask  destination ___.__.___.___
        ppp  txqueuelen 3  (Point-to-Point Protocol)
        RX packets 10  bytes 172 (172.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 9864041  bytes 5842982146 (5.4 GiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

In a 10-15 seconds it shows up to 5.4 GiB of packets. It grows very fast.

The same if firewalld is disabled.

I'm using Network-Manager to connect to pptp.
