Cannot Access ASDM Website

[Jason Van Assen]

Hi,

I've received two Cisco ASA 5505 and am unable to connect to the ASDM website on either. Ive done all the basics and but something is clearly wrong somewhere considering its happening on both.

With the default settings on the ASA I am able to ping the ASA from the laptop and vice verse however when trying to browse to https://192.168.1.1 nothing happens at all, no errors etc. IE just shows that the page cannot be displayed, have even tried chrome. Java is installed.

See running-config below:

'no webvpn' and try again?

I tried "no webvpn" command and then write mem. Still no luck browsing to the ASDM.

The ASA came with an ASDM image onit obviously and i have also tried downgrading the ASDM and ASA's to a much older version, still not luck.

I even loaded an ASA & ASDM image onto the ASA device and loaded a config from a live ASA we have here onto this but still no luck.

Did you upload an ASDM image to the ASA and configure it "asdm image flash:/ ..."  ?

Hi Jason,

You need to define path of ASDM where it is located in flash?

Mahesh

This has been done also:

asdm image disk0:/asdm-711-52.bin

Hi,

Thanks for this link but none of the issues in there are the issue im having.

Thank you all for your help so far, no luck yet though....

hi jason,

try using ASDM 7.1(3) instead.

see compatibility matrix below:

http://www.cisco.com/en/US/docs/security/asa/compatibility/asamatrx.html

[Jason Van Assen]

Thanks John, il give this a go also

[Andrew Phirsov · Accepted solution]

Is this present in the config?: ssl encryption 3des-sha1 aes128-sha1

[Jason Van Assen]

Not as far as i can see......

Is this something that should be there?

Thanks

[Andrew Phirsov]

It is.

[Jason Van Assen]

Thanks Andrew, through your hint ive finally got it working after quite a few days.

Upon entering "ssl encryption 3des-sha1 aes128-sha1"

i was getting the following error: "The 3DES/AES algorithms require a VPN-3DES-AES activation key."

I googled this error and came across the following article http://www.booches.nl/2010/12/cisco-asa-web-interface-not-working/

which mentioned about installing this VPN-3DES-AES activation key. I went onto this Cisco site and requested this activation key and after installing the key that was sent to me and then re running the ssl encryption key i can finally get onto the ASDM.

I dont fully understand why this was needed and havent had to do this before in my limited experience with ASA's could some perhaps break this down for me and give me a little explanation. Would be much appreciated.

[pankaj29in]

Looks like you didnt go though the document which i gave you earlier ..

same was there too.
