Routes – after VPN is connected

zeal@kplabs:~/Documents$ route –n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.225.1   0.0.0.0         UG    0      0        0 wlan0
172.27.224.0    0.0.0.0         255.255.240.0   U     0      0        0 tun0
  

If we compare the difference, there are two additional routes that are added after VPN is connected. I have created a test internal network with subnet 172.18.0.0/16.

If we look at the third line of the route, all the traffic to 172.18.0.0/16 network is being routed to 192.168.50.1 gateway, which is basically used by VPN.

So, essentially, all traffic, be it SSH, HTTP, HTTPS, or any destined for 172.18.0.0/16 network will automatically be routed via VPN server.
