[strongSwan] Interface address change not acted upon

Assume a client where charon is configured with a simple tunnel 
using left=%defaultroute right=vpnserver. On this client also runs a 
DHCP client (dhcpcd).

When dhcpcd changes the address on the only interface eth0 because the 
DHCP server handed out a new address, charon seems to continue to use 
the old address, despite having noticed that the old address is gone 
from the interface.

Is there a configuration option that I need to add so it will 
reestablish the tunnel using the new address?
