On that page, I read: ipfw queue 1 config pipe 1 weight 30 mask dst-ip 0x000000ff (ssh connections may use 100% of available bandwidth) What does tha value "weight 30" mean exactly? I'm not to clear with the man explanation: weight weight Specifies the weight to be used for flows matching this queue. The weight must be in the range 1..100, and defaults to 1.
