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.
