Setting up a site-to-site VPN & can't ping local IP's

I'm setting up two boxes to be a site-to-site VPN using cascading.

It shows that the servers are connected to eachother (screenshots: server 1 - http://prntscr.com/i9clol , server 2 - http://prntscr.com/i9cm10 )
however, I can't ping the internal IP of server 2 from server 1 and vice versa (eg. server 1's internal IP is 172.16.20.6 & server 2's internal IP is 172.16.20.7) (note, they ARE NOT behind the same firewall - they have different public IP addresses, only went with the same subnet schema for ease of use. I've also tried with two different subnets (10.0.0.5 & 10.2.0.5) but no use either)

Am I missing any linux routing rules or something?

Are these cascade connections connected each other? or connected another VPN server on somewhere?
