Cisco PIX Configuration

[BHconsultants88]

Hi guys

I need to change the following configuration on a Cisco PIX

ip address outside 95.97.7.58 255.255.255.248
global (outside) 1 95.97.7.59
route outside 0.0.0.0 0.0.0.0 95.97.7.57 1

Could someone assist me in how I'd change the IP addresses from CLI?

Thanks

Bal,

Sorry I didn't get back to you over text mate - got side tracked at work. Thought I would reply on here for a giggle.

Before you can start, you firstly need to know three things.

1. The new IP address for the outside interface.
2. The subnet mask for the outside interface.
3. The IP you wish to be the default route for the PIX (where it will route traffic if it cannot match against any other route statements).

Go in to global configuration mode (conf t) and find the outside interface number - "eth0" for example. From global configuration mode, enter the commands below replacing X.X.X.X with your new outside IP address, Y.Y.Y.Y with the subnet mask of the outside and Z.Z.Z.Z with the IP address of your default route (likely to be the ISP CPE connected directly to the outside of the PIX).

interface eth0
 ip address X.X.X.X Y.Y.Y.Y 
 exit
no global (outside) 1 95.97.7.59
global (outside) 1 X.X.X.X
no route outside 0.0.0.0 0.0.0.0 95.97.7.57 1
route outside 0.0.0.0 0.0.0.0 Z.Z.Z.Z

Have a go and let me know how you get along. If you hit any issues, just give me a ring, you have my number.

Cheers,

Luke
