On new WAN IP (DHCP Client) it takes 10 minutes to IPsec reconnects

[vitalisator]

Hi,

It seems that charon do not care or is being not informed after WAN IP address changes

it try still use the old IP address and cannot bind this.

i see this messages after IP adress is changed: (the XXX.XXX.180.28 is an old IP address)
Logs are in reverse order!
