What do you mean by 'catch' it ? I mean, I could say "wait till you see a SYN/ACK, and then grab the next one", or "look for a SYN, and then take the next one in the same direction", but I'm thinking that neither of those is probably the answer you want ? Tell us what you want to do with the packet and it might make the question a little easier. Antony.
