What do the numbers in brackets refer to in the IPtables filter file? i.e REROUTING ACCEPT [164:15203] :INPUT ACCEPT [164:15203] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [147:63028] OSTROUTING ACCEPT [147:63028] I am wondering as if they are necessary to be altered when i update my script? are they some sort of serial number like in bind? or are they ports from and too?? having trouble finding out what its for in google Thanks in advance
