If I had only one machine here then there is no need for a distinction, of course. I'm sure many knemo users fit that description --- perhaps bug report (enhancement request) 322 is beyond the scope of the app. I think it can be easily done and I like the internal verses distinction. However, as your dd-wrt router probably also functions as your gateway, its iptables code can easily check internal/external at the point it sits on the network. For a client machine to do it, it would basically just have to filter packets and say: if ip = mine; then it's local elif ip = myClassC subnet; then it's internal else it ain't local and it ain't internal, so it must be external. I'm just not sure how 'authoritative' an app like knemo could be on making that determination - I'm no routing guru. -- David C. Rankin, J.D.,P.E.
