Say that I am running a ssh server on port 22.
Normally, if you do
telnet servername 22
Connected to linux.private.net (xx.xx.xx.xx).
Escape character is '^]'.
I'd like to be able to
1) set up filtering on my server so that only certain
connect packets are answered... IP Address filtering
is not enough. I want a special flag/trigger/bit/signature/etc
so that only certain machines get the connect message even
if they are all behind the same NAT device.
2) set up something on the initial connect from the client
to trigger #1 above.
Can you do this is TOS and packet mangleing or something else
