Thanks for the followup post. Different VPN Clients capture and process 
IKE and IPsec traffic differently. We have invested a lot of time into 
making sure our VPN client doesn't interfere with other clients that may 
be installed ( only install divert rules for specific peer IP's and only 
process traffic which match our specific IPsec SA identifiers ). 
However, other VPN clients aren't nearly as accommodating and will try 
to process traffic that it shouldn't. This can cause the Shrew Soft VPN 
client to work incorrectly. Its all very implementation specific.
