The communication is running IPv4 packets tunneled under IPv6 packet and vice versa. The tunneling is done using gifconfig on gif0 and gif1. Should I: 1. tcpdump -w outputfile host and 2. tcpdump -w outputfile src port 3. tcpdump -w outputfile -i gif0 (this one doesn't seems to work) 4. tcpdump -w outputfile -i fxp0 Which are the things i should capture on, the hosts, the port 80, the gif0 tunnel interface or fxp0 ether interface? My aim is just to capture the performance between 6to4 and 4to6 2 host. Btw, the 2 host is assume to be isolated from the rest, and link-local meaning the communication between them is without third node joining. Thank you.
