topic Hi, in Network Security

Ask for ASA ?

khoirul.iman — Tue, 12 Mar 2019 06:49:33 GMT

Hi all,

I want to setup Cisco ASA Firewall. When I connect my PC to management int of ASA (192.168.1.1/24) I setup static IP on my PC (192.168.1.10/24), but my PC couldn't get IP which I set-the IP on my PC (169.x.x.x). Then I check my PC, I tried connect to another PC (point to piont) adn I got the IP static which I setup.

The last, I use another PC to connect ASA management int and the PC has same case-couldn't get IP static.

Thank you for help

Hi,

Factory default ASA have dhcp already configured and when you connect your management interface, you pc should get an Ip address automatically.

Your PC would get an dhcp ip in 192.168.1.0/24 where 192.168.1.1/24 is preconfigured on ASA management interface.

I couldn't get it when you say got the IP static. As a setting, leave your pc IP settings to Automatic(select the automatic radio button). Do not configure any static IP.

169.x.x.x is an APIPA IP which windows PC automatically generate when no ip from DHCP or static assinged to the nic.

Also you could disable firewall settings on PC. or else you might not be able to ping ASA interface IP.

For more reference, use the link below:

http://www.cisco.com/c/en/us/td/docs/security/asa/asa72/configuration/guide/conf_gd/start.html#wp1053876

This is for 5510. If you have ASA5505 then follow below link:

Hope it helps.

Hi there,

Please always open separate thread for new issues.

bdw, you are opening a less compatibility ASDM versio as per ASA version. Use the link below. After that there could be java version issues. Therefore Copy the latest ASDM version asdm-751-90.bin

Hi,

Adding to Akshay's suggestion, please run the command "show run all ssl". It looks like the 3DES-AES license is disabled. Normally you need to enable 3DES and AES encrytption in the SSL configuration so that SSL handshake is successful. Please try to access the device via web browser and verify whether you are able to access the device via HTTPS.

Thanks

Hi,

Hi,

Use SN : JMX1513L0BV(it is in ur 'show version' output for the generating 3des license key. It is a free key which you could be generated from cisco.com/go/license. Use the link below :

As soon as you activate this key, you would have many option to add for ssl encryption. Add all the available option.

Here are the steps to follow in order to generate the activation-key:

www.cisco.com/go/license

- Click on "Product License Registration" Tab on the Right.

- Click on Get Other Licenses dropdown menu on the Right and select "IPS, Crypto, Other..." link

- Select "Security Product" from the Product family and Select Cisco ASA "3DES/AES License".

- Enter the Serial Number of the ASA.

- Next and then Select the “I Agree” check box and Type your “Email Address” and Click Submit.

- Activate the License Key on ASA with the "activation-key" command in Configuration Terminal Mode. Do not reload the ASA and check the license once again with 'show activation-key'.

now add all the encryptions with 'conf t)#ssl encryption ?

now add all the encryption one after the other with space and hit enter.

Then try.
