Any kind of VPN creates a virtual network card, that's it.
When you run any VPN client, all IP traffic goes through virtual network card except LAN traffic.
If you run the previous route add command, however, it tells system any traffic that go to 162.39.147.58 please use router gateway IP 192.168.10.1 instead of the VPN if your physical network card IP is in 192.168.10.x range.
You can always delete the route with "route delete" command if it doesn't work.
I'm done.
