I have VPN network (PPTP protocol), When established connection to VPN server I can see VPN network tunnel in output ip command and table route with netstat command but I cannot access to internet and VPN network unless I disconnect VPN network in Fedora 27


How reproducible:

Just add new VPN (PPTP) network 

Steps to Reproduce:
1.add gateway
2.add username and password
3.keep another default settings

Note:firewalld off and routing table same and SELinux disabled

When I downgraded kernel to 4.8.6-300.fc25 version everything works fine
