Hi , Is it poosible to specify all elements in the 5-tuple, srcIP, srcPort, protocol, dstIP, dstPort ,to iptables for filtering? for example, iptable ... 192.168.1.1, 12345, 6, 64.58.79.230, 80 ... Any of the elements may be a wild card or a subnet, i.e 192.168.1.1/16 ,12345 - 12400, 6, 64.58.79.230, 80 thanks
