You have to define a subnet for Side A giving it a single ip and creating a loopback device on Side A server so that there actually is traffic from a acceptable source to go into the tunnel...

Something like 


and the respective loopback device in /etc/network/interfaces

auto lo:11
iface lo:11 inet static

should do the trick.

Please include configuration files even when it is not working in your questions.

Best regards
