Hello

Iīve received in recent time a new Cisco Pix 515e.

Itīs home configured with an 192.168... Lan IP address but I wanted to
configure it with a new one (172.16...) using the web interface provided by
the machine.

The problem is that when I change it using the web interface, I can get a
right ping (using 172.16...) but web access itīs totally unreacheable.

Because I canīt use the "save" command I restart the Pix 515e again and the
old 192.168... address arise.

What do you thing Iīm doing wrong?

Thanks you all in advance for your help

Hi I am no Cisco expert as I have only recently just studied my CCNA (yet to
take exam) but using the CDM is, I am told, unreliable and needs a lot of
RAM for the router to run it. Why not change the address from the CLI and
save the configuration.

Commands as follows:

#conf t
#interf ether0
(conf~t)#ip addr 172.16x.xxx.xxx 255.255.0.0
press CTRL & z

#copy run start

Hope that helps.

What do you mean you cannot save ?
If you change the IP address on the inside interface, you will also have to
change the addresses that the PIX will allow HTTP access from.
If you need more guidance, e-mail directly.

You need to change more than that.  Since you're changing the network number of
the inside interface from 192.168.x to 172.16, you'll also need to change the
actual network environment attached to that interface.  At the very least, if
that environment consists of just a crossover cable to your pc, you need to
reconfigure the pc's interface so it now also lives on 172.16.  If you're
routing thru some other subnets to reach the pix, you're in for a bunch more
trouble.  All of which really points to the fact that the web interface is just
not appropriate for all types of changes.  If you're messing with anything that
affects your management access to the device, you should just attach a console
cable and configure it thru the cli.
