Come to think of it, when I do not have exclusion (!), the comma symbol (,) between sets in brackets indicates logical AND (in other words, to have a packet match all sets specified in the brackets must also match), so following this:
!+[ipset1,ipset2...ipsetN] should be interpreted as NOT (ipset1 AND ipset2 AND ... ipsetN), which is the same as ipset1 OR ipset2 OR ... ipsetN - in other words match in either set produces a packet match. Similarly +[!ipset1,!ipset2...!ipsetN) should be interpreted as (NOT ipset1) AND (NOT ipset2) ... AND (NOT ipsetN), which is the same as NOT (ipset1 OR ipset2 OR ... ipsetN) - in other words match in either set does NOT produce a packet match. Does your patch reflects the above logic or should I refrain from applying it until you fix this? ------------------------------------------------------------------------------ Beautiful is writing same markup.
