Just finished up my IPSEC testing.
A vaio laptop is connected via cat5 to a m0n0wall box (4511 w/HIFN)
A pIII server is connected via cat5 to a m0n0wall box (4511 w/HIFN)
The m0n0wall boxes are connected to each other via wireless ad-hoc WAN.
40bit WEP was used.
3DES & MD5 encryption and hash used for the tunnel.
IPSEC w/o WEP 768bit Aggressive 2.45
IPSEC w/o WEP 1024bit Aggressive 2.41
IPSEC w/o WEP 1536bit Aggressive 2.43
IPSEC w/o WEP 768bit Main 2.44
IPSEC w/o WEP 1024bit Main 2.43
IPSEC w/o WEP 1536bit Main 2.45

I believe it is safe to say that the HIFN card is being used, and that
the speed limitation lies in the wired/wireless conversion. It would be
interesting to see throughput from a pure wireless client.
If anyone has a 4521 and would be willing to run these same tests that
would be very interesting information.
