I have a ASA5510 with a 2811 router on the outside. if i try to access to manage the 2811 via telnet or the GUI it fails. the only way i can access it is to use a console cable on the 2811 and make my changes. i would like to be able to reach it from my desktop computer (which is on the inside of the asa). what should i be looking for on the asa to allow this?
