"-A" appends a rule to the end of a chain, "-I" inserts a rule (by default, at the top) of a chain. If you want to log ALL new connections from box6 (remember that the "-s" bit is specifying connections coming FROM box6), use the "-I" version. If you want to just catch connections not already handled by the rules, use the "-A" version. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, C2 Hosting ricks@xxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - I haven't lost my mind.
