Since 63.140.157.231 falls within 63.140.157.0/24, this is a slightly
complicated setup. You have two options:
a) Run a proxy arp daemon for 63.140.157.231 on the private subnet (on
the same host as tinc runs) and add "Subnet = 63.140.157.231" to
hosts/joel. You also need to ifconfig the tun interface properly in the
tinc-up scripts.
b) Run tinc in bridging mode by adding "Mode = bridge" to tinc.conf.
Create bridge devices on both sides and attach the interface of the
private net to the tun interface.
The first solution is easier, but the second will allow you to browse
the Windows network neighbourhood from joel, and will also allow you to
run IPX applications or applications that use multicast or broadcast
packets.
