I'm trying to develop a packet sniffer using java and I've been using the JpCap library to capture the packets. I've run into a problem where Jpcap is capturing the packets from the NIC on my desktop, but I need to capture the packets from the gateway (MikroTik RouterBOARD) and not just the packets coming into my system.

I've been reading into 'promiscuous mode', a parameter passed into the JpcapCaptor.OpenDevice() method. I'm a bit confused about it, will promiscuous mode capture the packets from my router or does it do something else?

Sorry if I haven't explained it properly. here's the tutorial I was using http://netresearch.ics.uci.edu/kfujii/Jpcap/doc/tutorial/index.html

Thanks for the help!
