[c-nsp] L2 payload encryption -not p2p

[Adam Vitkovsky]

Hi
Can anyone recommend a device than could be placed inline between a server
and a switched infrastructure that would encrypt L2 payload for
communication between two such servers (round 100mbps)
I imagine one would need two such devices one at each end (or maybe a NIC in
a server)
Or is ASA capable of encryption in L2 transparent mode please?
