I received a notification from my firewall software that Shrewsoft's latest VPN client (version 2.2.2, released 2013-07-01) appears to be calling home. The ipseca.exe file included with the client is attempting to make an https connection from local port 63467 to remote port 443 at www.shrew.net (220.127.116.11).
Note that this connection request comes after starting the GUI VPN connection manager, but before attempting to open the VPN link.
Why would this be? Why would Shrewsoft's server need to be involved in establishing a VPN connection?
