Is there a way to do this?
If not would you be able to do this on a pc with two ethernet cards. one connected to the internet and the other bridged with the console connected?

Hey there,
You certainly can do this,
Whilst I dig up the information on the port mirroring, can you confirm which router you're using? The TG585 or the 582? I believe the process is the same, but just to make sure I get you the right commands for the telnet session.
Cheers,
Matt
