Hi, I don't really know if this is the correct list for asking this, if not a referral to the correct list would be very much appreciated. Ok here it goes. I would like to create a u32 filter for tcp packets that are larger then 1480 bytes but I am not really sure how of if this can be done. I know about the pattern and mask thing but I am not terribly familiar with the masking thing. I think my ip basics are good enough though. Second question I have is another rule I would like to create for packets that are destined for the ports 441,412&413. Can I create one rule for that or should I create 3 separate rules? Last question accept for the linux advanced routing & traffic shaping how to is there a place where I can get more info & examples on the u32 classifier?? Thanks in advance Kim _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
