! (ip.src = 10.43.54.65 or ip.dst = 10.43.54.65) In the video below, I use a trace file with DNS packets show you how to filter for a specific DNS transaction as well as how to add response time values as a column. This translates to "pass all traffic except for traffic with a source IPv4 address of 10.43.54.65 and a destination IPv4 address of 10.43.54.65", which isn't what we wanted. Filter out any traffic to or from 10.43.54.65 The same is true for "tcp.port", "udp.port", "eth.addr", and others.
For example, "ip.addr" matches against both the IP source and destination addresses in the IP header. sounds like you are seeing dns requests for A record for ipv4, codeA, and ipv6, codeAAAA. This translates to "pass any traffic except with a source IPv4 address of 192.168.65.129 or a destination IPv4 address of 192.168.65.129"ġ5.Some filter fields match against multiple protocol fields. Can you post a wireshark capture so I can see. Are these two IP addresses the same ANSWER. For filtering only DNS queries we have 0 For.
