How can I access my own IP under StrongSwan? [MacOS]

I've set up SoftEther VPN on a brand-new Ubuntu 16.04 server and connected macOS, Windows and iOS client to it.

I've created Ruby on Rails webserver on my macbook and binded it to my VPN address.

Other clients can access it but not my macbook - I can't even ping my macbook's IP from itself.

I've had an access to macbook's VPN IP yesterday - but it suddenly broke so I can no longer have access to my own IP.

The same thing happened to my Windows PC - but it can ping its own IP and access webserver from curl. Unfortunately, Edge and Internet Explorer are refusing to load the website (timeout).

I am using static IP for my macbook and entered the netmask, gateway and IP in the macOS Network Settings.

How can I fix it so my macbook and Windows PC can access own webservers hosted on VPN IP?

Here is my macbook's ifconfig:

I've finally found the answer. I've got to add route linking my VPN IP with my mac's localhost interface.

sudo route add -net 10.17.0.17 127.0.0.1

Then, I've enabled that route on every VPN connection success:

sudo vi /etc/ppp/ip-up
#!/bin/sh
/sbin/route add -net 10.17.0.17 127.0.0.1

And now it works like a charm! Thanks for your comments.
