Remotely Change IP Info in ASA

whisperwind · ‎02-18-2009

Have a remote site that is changing ISPs, I need to change the outside interface IP Address / Subnet Mask and the ASAs default gateway, how can I change all three remotely at the same time?

Load the new config to the startup-config via tftp and reload the firewall.

Thank you, can you be a bit more verbose, when I do a show flash there is no startup-config.

Is it a text file, invisible or something else?

Sorry I don't think you can see the startup-config in the file system. But you can do the following command which will upload a file to the startup-config.

copy tftp: startup-config

Also, make sure you don't do a wr mem after the upload as this would write the running-config back to the startup-config...

I don't think the file has an extension, I would first tftp a copy of the running-config to your machine, then edit the file with notepad and tftp it back as the startup-config. Hope that answers your question.
