I'm connected to an ASA 5505 via the console cable and I know what changes need to be made to the config file but I'm not well-versed in this and am nervous about making the changes. I need help/advice with two issues:
1) I have to add a few lines to the config file to open a port. I know what lines I have to add (thanks to other users here) but I have no idea how to get them into the config file.
2) I DO NOT want the changes I make to overwrite the existing config file and I'm worried that when I add something it will create a new file in place of the old one. How do I add the lines while ensuring that the existing config file remains intact?
Can anyone offer assistance with these two issues?
