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!

Try to disable webvpn completely if you are able to connect then upgrade. Also please add the next:

asdm image disk0:/asdm-645.bin

FYI: I still believe it’s a bug, and by the way upgrade to asa825 interim release don't go any further because NAT concept has a configuration change that takes time to understand.

Call the 800 553 2447 and explain your situation, give them the bug ID that I have posted, have them check the serial number for warranty also.

I upgraded the ASA to 8.2(5)46 and ASDM to 7.1(4) and there was no change.  The workaround says to disable webvpn so I entered the command no webvpn but afterwards I can no longer access the vpn - how to I re-enable the web vpn?

[jumora]

Did you change the the asdm image of the unit, just reload the unit will restore the configuration but you can also run copy startup-config runnning-config

[jumora]

If you decide to reload make sure you don't save the configuration.

I am from TAC if you give me a number I can help you out, I think we are just going to extend this if we continue over support forum

[rmendoza3]

Thanks, I found the command to enable webvpn so the vpn is accessible again but I'm back to where I was.  The vpn wizard indicated that adding /admin to the https vpn url would allow access to ASDM.  Using /admin, I can get to the cerfificate warning but after that the Page can not be found.  I'm not able to get to this step:

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

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

VPN management access is new to me, can you tell me what I'm supposed to be seeing?  Is it the same ASDM launcher that I use when accessing the ASA using a browser on the inside network?

[jumora]

Appliance will request an IP(in your case put the inside) just like web access and it should not have a problem but as I said it seems that we are getting nowhere with the support forum and we need a webex and do a little more troubleshooting that we can't do over forum.

[jumora]

please post show tech with current configuration settings.

[rmendoza3]

I think the issue might be because I did not add a vpn ip pool.  I will make those changes and see if it works.
