Hi all!

 

If I have a packet with protocols like eth:vlan:ip:udp:gtp:ip:tcp, is there a way to filter in one of the IP headers only?

I know I can do frame[22:2] == D4:DD (here IP ID of first IP header), but it's not very dynamic, so if for some reason the bytes are in different places, this would fail.

 

Another work-around I've tried is to list one of the IP IDs with tshark and grep.

 

Thanks,

Martin
