Hi, That's not a problem. In **promsicous mode** (checked?), you will see any traffic coming out of the mirror port, regardless if it's on your local subnet or not. Have you tried sniffing without any filter? Do you see the traffic of the other subnet then? I suspect your problem is more related to your port mirroring setup than to Wireshark filters.

I did a port mirroring on a Layer3 switch so on the mirroring port I can see all the packets of some subnet and they will necessary not match my eth interface subnet ..... Thanks !

Hi, Would that be a capture filter like: 'port 53 or port 5060' Thanks, Jaap On Thu, 29 Apr 2010 11:39:17 +0200, "marco\@marcomp\.it" wrote:I need to filter some traffic (before capturing it) using the pcap / winpcap filter but this traffic comes from some different subnet ( different from my eth interface subnet ). So if I apply a filter the pcap show me the packet that can lookup on my eth interface only ... How can I get the filtered traffic that comes from "everywhere" (0.0.0.0/0) ? I need to filter the data traffic before sending it to whiresharkbecauseI only need to check the DNS and SIP traffic for a long time ( may beformore than 1 week )... so I don't want to store Gbyte and Gbyte of not helpful data on my pc..... Have you any suggestion ?
