nevyana — Mon, 11 Mar 2019 23:39:47 GMT

hi,

cannot access to cisco asa5510 asdm nor ssh thru anyconnect vpn, attached is the current configuration. user authetnicaties aaa locally and has admin service-type. When vpn session is established, it lets me go thru the certificate warning and when trying to install the asdm laucher its failing. ssh access is enabled but not working. i can access both asdm and ssh from the inside network, and from a pc on that network. thanks,

vpn access to asa5510 asdm and ssh not working

You would need to add the following:

ssh 192.168.25.0 255.255.255.0 inside1

http 192.168.25.0 255.255.255.0 inside1

Then you should be able to ssh and asdm to 192.168.1.3 from AnyConnect.

I could download the ASDM and install it from 192.168.1.3 but still cannot lauch it with 192.168.1.3 (neither ip) and cannto ssh into the unit 😞

Does it fail authentication, or you can't even establish connection to it?

Can you telnet on port 22 or 444 using command prompt to the inside interface ip from AnyConnect?

If you use the username: admin to connect, does it work?

yes, i can telnet to port 444, not 22 from the inside1. On the ASDM laucher 'unable to launch device manager from 192.168.1.3", tried both admin and vpnadmin users.

i am browsing cisco documentation, found this document http://www.cisco.com/en/US/docs/security/asa/asa84/asdm64/configuration_guide/access_management.pdf

From the Configuration > Device Management > Management Access > Management Interface pane,

choose the interface with the highest security (the inside interface) from the Management Access Interface

drop-down list. Changed the security level on the management interface to higher and management-access to management. Now I am able to login with ssh. My inside interfaces where set with the same priority, maybe that could've caused an exception ?

ASDM was still failing until looking at wire shark, I am sending requestes to the mangement interfacethru port 443, changed the http server on the asa from 444 to 443. Now that is working. Phew....

thank you for your support.

Jennifer Halim — Thu, 09 Aug 2012 12:43:03 GMT

Ahhh, that's why i ask you to test telnet to port 444 because it is configured to accept connection on port 444

Glad to hear all is working fine now.
