i've now testet this device here: http://www.ipc2u.de/catalog/E/EL/33640.html
my config: linuxbox1 <-> new box obsd 3.9 <-> pc obsd 3.9 <-> linuxbox1 between the new box and the pc with obsd 3.9 is a ethernet crosscable. on both boxes is running a ipsec tunnel with isakmp with aes encryption and rsa authentication with 4096 bit. throughput: i've transferred a 100M file with scp from linuxbox1 to linuxbox2: 5,4MB/s linuxbox2 to linuxbox1: 5,1MB/s CPU peak 80% average 60% This seems very good. i've now ordered a second box and will made a throughput test with the ralink cards.
