<p class=MsoNormal>Hi, I’m at the point where my Vista client will
generate the following messages on the server but never completes the
connection. I’m using mostly the default configurations as well as copying
some of the delivered example configurations…see below. I’m currently
on the same switch with the host because I’m trying to validate the
configurations before I send the host to its final destination. The Vista
connection settings are as described in <a
href="http://www.jacco2.dds.nl/networking/vista-openswan.html">http://www.jacco2.dds.nl/networking/vista-openswan.html</a>
using PSK only for now. Thanks in advance.<o:p></o:p></p>
