I have a Pix 520 and run a private network behind it. Corp. told us we need to change the the second octet on our IP scopes. Currently we are on 10.76.x.x and need to go to 10.78.x.x. My question is we have a lot of access list in the Pix and I don't want to remove them and readd them again just to change the 2nd octet. Can anyone suggest a way to change these ip's without removing the ACL's.
Thanks....
