Hi Michał,

IPsec over TCP is not defined in any standards document that I know of. 
The Shrew Soft Client implements IKE/IPsec by following these standards 
documents. While it may be possible to get this working for Windows VPN 
users, it wouldn't be possible on any other platform supported by the 
client since it relies on existing kernel support to handle the IPsec 
transport ( ie. Linux/BSD has no IPsec over TCP support ).

Sorry I can't be more help,

-Matthew
