Hey all, Just finished up my IPSEC testing. The Setup: 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. The Throughput: mbits 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 IPSEC w/WEP 768bit Aggressive 2.43 IPSEC w/WEP 1024bit Aggressive 2.39 IPSEC w/WEP 1536bit Aggressive 2.41 IPSEC w/WEP 768bit Main 2.44 IPSEC w/WEP 1024bit Main 2.42 IPSEC w/WEP 1536bit Main 2.42 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. --Michael > -----Original Message----- > From: Manuel Kasper [mailto:mk at neon1 dot net] > Sent: Friday, June 06, 2003 4:32 PM > To: Michael Iedema > Cc: m0n0wall at lists dot m0n0 dot ch > Subject: RE: [m0n0wall] Some throughput testing > > > On Fri, 6 Jun 2003, Michael Iedema wrote: > > > I'm guessing the speed increase would be due to the extra 33mhz you > > possibly have.
