Hi, I have a capture file having protocol stack as eth-II/ip/udp/gtp-u/ip/tcp/application. And my ip filter expecting packets having ip address x.x.x.x over GTP-U. But i found the filter "rc host x.x.x.x" only takes the IP header over eth-ii layer for its filtering. Is it possible to filter the IP over GTP using current BPF-syntax or any tips to modify the codes for bpf so that it will work for gtp. Ambika Prasad Tripathy NetHawk Networks India Pvt. Ltd.
