Does anyone know of a device that connects in an AUI cable between an
ethernet transceiver and an attached device that will encrypt only the 
data part of the packet.

More exactly I'd like to find a device that will work in a routed TCP/IP
network.  The device has to be TCP/IP aware.  It can`t step on routing
packets and nessary broadcasts that some other unaware device would need to
properly route the packets.  I have heard of devices that encrypt an
ethernet but they encrypt everything above the MAC layer and routers
won't work with what's left.

I'm not worried about traffic analyists finding out who's talking to who 
just so long as the user information is encrypted.  Also this will be used 
on international circuits so it would be nice if it were exportable (with 
the proper paper work if necessary).

This function probabily belongs inside a router but cisco hasn't been very 
interested.  Maybe someone out there has hacked a copy of PC route?

Thanks - Bill


Ideally it would just sit in the AUI cable between a
