Cisco ASA 5505

Hi Experts,

I'm using IE (https) to try to change the default ip address from 192.168.1.  to my preferred LAN ip address, whne it try to send the command to ASA, it doesn't get through.

I even tried with the wizard but again it doesn't complete the changes.

I have not tried the console yet to change the default ip.

Any suggestion?

When you say it "doesn't get through" what exactly happens? IS there an error?

Obviously if you change the IP when connected to the old IP  you will lose connectivity. So you can go into configuration (assuming you are logged into it with level 15 security) change the interface IP and then click apply.

After you click apply you need to close the browser, which is easier to just close the smaller window which loads the applet as it will close them both. Then browse to the new IP via HTTPS and make sure you save it.

Console is the best way to do this, but via browser works too you just have to go through more steps.

Hope that helps!
The browser setup on the ASA works sometimes... If you can avoid it, please do so. Instead use the ASDM startup wizard if you don't know a lot about the ASAs or PIXes. If you are familiar with the ASA, I recommend using the CLI for management instead.
If you need help with configuring it for internet access let me know - I'll send you the commands to put into the console.
Cheers! :-)

There is an issue with the ASDM when I try to reach the router, see enclosed so I resorted to IE but cannot change the bloody ip address since it doesn't complete the changes, ie error in command etc.etc

By default, the router can be reached through HTTPS/ASDM, so how do I change the vlan1 ip address through CONSOLE, then change it back to HTTPS/ASDM. At the moment, I cannot even access it through HTTPS, it says 'done' on the bottom left hand corner. I'm thinking about pressing the 'reset' button.

Become an IT Security Management Expert

In today’s fast-paced, digitally transformed world of business, the need to protect network data and ensure cloud privacy has never been greater. With a B.S. in Network Operations and Security, you can get the credentials it takes to become an IT security management expert.

On console to enable ASDM access run the following commands (replace xxxxxxx with your password - passwd and enable password must be different - WRITE THESE DOWN- THESE ARE YOUR MASTER PASSWORDS):
passwd xxxxxxx
enable password xxxxxxx
interface vlan 1
nameif inside
ip address
security-level 100
no shut
interface ethernet 0/1
switchport access vlan 1
no ip address
no shutdown
crypto rsa key generate mod 1024

http server enable
http inside

Connect the PC to the ASA on ethernet port 0/1 (second one) and assign the PC a static IP of with a subnet mask of and a default gateway of
Now try accessing the ASDM with a blank username and your passwd (not enable)
You can now run the startup wizard.
Cheers! Let me know if that does it!

By default, asa appliance can only accessible by https/asdm?

So the issue is  I'm connected to ASA by console, then power restart it, open a terminal session but all I can see some wierd characters.
You can always access the console (unless you lock yourself out of it when configuring AAA).
Make sure your console settings are:
speed: 9600
data bits: 8
stop bits: 1
parity: none
flow control: xon/xoff.
I use a terminal program called putty. It's very good. Probably the most popular one out there.
One other thing: you should NEVER have to power cycle an ASA unless you're upgrading the software or the activation key. Just letting you know. :-) These devices are designed to run for years without stopping provided you don't reboot them - even when the config is completely changed you shouldn't ever have to reboot it. Restarting it won't fix anything unless you didn't save the latest config - it will just reload the last saved one on reboot - but you lose everything you've done on it since last save.
