Just a question I don't seem to be able to figure out while googling on it.
I got an m0n0 1.3b5 box running to test with an miniPCI wifi card with chip
This card is capable of 26 dB power and to be legal here I have to put power
down to 20 dB.
When I look at the ifconfig I see an value of txpowmax 38. How does this
relate to the power in dB or mW ?
If this value 100% of the max thus 26 dB ?
If so then 26 dB is 400 mW is 38, 20 dB is 100 mW , thus 1/4th of the max
power and I have to put it on 9.5 ?
If anyone knows how to do this, or can point me in the right direction where
to find the info I would very much appreciate it ! :)

Onderwerp: Re: [m0n0wall] 1.3b5 and filtering bridge/traffic shaper on ALIX
I have found that disabling traffic shaping causes firewall states to be
properly shown, but after enabling it no new firewall states are being
displayed. Also, traffic shaping does not appear to be working in
combination with the filtering bridge.
