I've tried https://10.0.0.1/admin with my laptop with an IP 10.0.0.5

And int the http configuration i've tried http 10.0.0.0 255.255.255.0 inside but i couldn't get into web browser and i tried 255.0.0.0

and i didn't change it back

I want to know why this is not working

and sorry about my poor english

The 3DES-AES license is free. Just go to software.cisco.com and log in there.

Under classic licenses you can request the license. You will need only the appliance serial number.

Check the license ("show activation-key") to verify that you have 3DES-AES feature licensed.

Also you need to use port 4443 because that's set in the configuration. So browse to:

https://10.0.0.1/admin:4443

Thank you for the answer.

I have checked the license, and there is no licence on it. I think because of I've got the old device from my

friend.

OMG I didn't know that

Thank you so much

was really helpful to me

jhseol@ugent.co.kr · ‎05-17-2018

can I ask you one more question?

I can't find class license menu at software.cisco.com

Marvin Rhoads · ‎05-17-2018

Sorry - -the term they use on the page is "Traditional" license.

Here is the sequence of screens you should see and use:

Thank you so much!!!

Hope you have great day!

jhseol@ugent.co.kr · ‎05-22-2018

Hi, i've got a licence from software.cisco.com.

However I still can't access with browser.

this is my new configuration

I tried https://10.0.0.1:4443/admin and

https://10.0.0.1:4443

and my labtop had 10.0.0.5 255.0.0.0

ping was working well

Marvin Rhoads · ‎05-22-2018

Try removing this line:

ssl encryption des-sha1

i.e.,

conf t
no ssl encryption des-sha1
end
wr mem

That line is forcing SSL to use weak encryption which most modern browsers will reject as insecure. Removing it will allow the ASA to behave in the default manner and negotiate the strongest mutually acceptable algorithm with your client PC.

jhseol@ugent.co.kr · ‎05-22-2018

still doesn't work...

jhseol@ugent.co.kr · ‎05-22-2018

i tried no threat-detection basic-threat
no threat-detection statistics access-list

and no encryption des-sha1 and change port number to default.

Then it finally works now!

Thank you for helping me!
