Simplify PIX configuration changes?

kirbyellis · ‎05-17-2006

I have recently had an application move from one server to another. Is it posibble to simply redefine the "names" statement to use the new IP address?

eg: previous statement;

name 10.1.1.1 WEB_SERVER

proposed statement;

name 192.168.1.1 WEB_SERVER

This would allow me to perform only the single config change, as the name is already associated with an object-group, and that group is associated with an existing rule.

Thanks in advance.

Cheers, Kirby.

Hi ... that will be great but unfortunately it is not possible. This is what would happend.

1.- when you type in no name 10.1.1.1 WEB_SERVER ( as you can't have a name map to 2 IP addresses at the same time ). All you entries referencing to WEB_SERVER will show up as 10.1.1.1.

2.- When you type in name 192.168.1.1 WEB_SERVER to "remap"the name .. the old references to WEB_SERVER will remain as 10.1.1.1 and only new entries will be mapped.

I suggest you to :

1.- type in show run | inc WEB_SERVER and copy the output to notepad.

2.- Rename the map accordingly

3.- Find/Replace WEB_SERVER by 192.168.1.1 from the output on point 1.

4.- You can apply the new config accrodingly by copying and pasting

5.- Remove any reference to 10.1.1.1

No nice .. but it is the only way ...

I hope it helps ... please rate it if it does !!!

What if I first remove the mapping of

object-group network SERVERS

no network-object host WEB_SERVER

and then re-define the IP address of WEB_SERVER from:

name 10.1.1.1 WEB_SERVER

name 192.168.1.1 WEB_SERVER

I know that this is one more step than I originally intended, but I think it should still work.

Whadyareckon?

hi .. wait .. are you referencing the WEB_SERVER on the access-list by using the object-group SERVERS. Because if that is the case then yes .. you are correct .. I thought your access-list was referencing your server by its host name WEB_SERVER ..
