backup and restore configuration

[brentwoodind]

I am a novice when it comes to PIX. We rarley touch the configs.

I need alittle clarification on backing up and restoring a config via tftp or hyperterminal.

I have a PIX 506e running 6.3

I am going to be adding an ISA server behind it, and configure a DMZ between the two. So I need to change the Internal IP of the PIX.

I want to create a backup of the config so incase I need to revert back to the original set up incase things dont work out.

to back up to a TFTP server is it

write net "tftp ip"

or

config net

commands?

what command is needed to restore the config via tftp?

Or is it easier to copy the config with hyperterminal. copy the text form and paste to the PIX?

How do I overwrite the running config if I paste, becasue it merges the two?

Lets suppose tftp server is running on a workstation with the IP address of 10.10.10.1 and tftp server is connecetd to outside interface.

On pix to backup config

pix(config)# tftp-server outside 10.10.10.1 mybackup

pix# write net

on pix to restore

pix(config)# configure net 10.10.10.1:mybackup
