Hi KM,

Something that would be helpful is for you to produce a log output from 
both the Windows machine and the Linux machine for us to compare, using 
the instructions on these pages:
http://www.shrew.net/support/wiki/BugReportVpnWindows
http://www.shrew.net/support/wiki/BugReportVpnUnix

Another thing to try would be the latest Shrew 2.2.0 beta, which can be 
downloaded from http://www.shrew.net/download, although you may need to 
build it yourself.

Out of curiousity, are either of the OSes in a virtual machine?
