ASA 5510 ver. 8.2(5) Management access through clientless VPN?

[rmendoza3]

Hello all,

I'm completely new to Cisco networking and VPNs, I'm working on an ASA 5510 vers 8.2(5)46.  Right now the unit is set up very minimally.  Management access is accessible from my inside network at 192.168.2.1.  I'm trying to allow remote management access by VPN.  I created a clientless SSL VPN, which during the wizard process, indicated management access was by the adding /admin to the VPN's https url.  Adding the /admin to the VPNs url does not get me to the VPN login, and using the /admin url from the portal returns an "Unavailable" message.  Also, from the portal I can't access the ASDM using the inside network management IP, it also returns the message as "Unavailable".  Again I'm new at this, any help would be greatly appreciated.  Here's my config.  and Thanks!

With help from jumora I have internet access working on the inside interface, still working on the vpn issue though...

[jumora]

enable

config t

webvpn
no enable inside

Try to access the ASDM

[rmendoza3]

I've edited my original post and added the updated config. I'll give it a try...

[jumora]

But I think that the issue is that you don't have ASDM image if not this could be related to:

[jumora]

Yeah its the bug that I mentioned:

Symptom:

Unable to launch ASDM when webvpn is enabled on ASA.

Conditions:

ASA running version 8.2.5 and ASDM 6.4.5/6.3.4

Webvpn enabled on ASA.

On trying to launch ASDM, the following error message is seen,

"unable to launch device manager from x.x.x.x"

Configuring http server on a different port(4443,8888 etc) does not help.

Workaround:

Webvpn  needs to be disabled completely from ASA with the command "no webvpn".  Disabling it from the interface is not sufficient.

Let me add some detail to my "no access" answer.  Before I entered the commands, adding /admin to the https vpn url would result in "Page not found".  After I made the change I can get to the certificate warning but when I tried to continue to page then I would get Page not found.

Sounds like I need to update version?

[jumora]

Yes, just update and let me know if you need assistance I can help just tell me where to reach you.
