I have a Cisco ASA5505 Firewall that I need to reconfigure. I will be changing from DSL to Cable and will be receiving new incoming IP addresses. I need to be able to keep our network running during the change. I have an FTP sight that is plugged into one of the ports as well. I am very unfamiliar with the device but I am able to get into the GUI to change any setting but do not know how. Can someone offer any advice on what needs to be changed, how to change it or where I can look to change it?
