Do you also have a netmask of 255.255.255.255? This is a limitation of the Windows TAP driver... which I believe is down to a fundamental limitation of the Windows network stack. It needs us to pretend to be Ethernet and even fake doing ARP for the "router" on the subnet. Perhaps we need to reduce the netmask to a /31 at least for the benefit of the TAP driver? And maybe for the configuration given to vpnc-scripts.js too?
