Cisco Firewall :: ASA5520 Monitoring Connection / Disconnected In ASDM
Jan 25, 2011
I have a 5520 ASA running 8.2(1) and ASDM 6.2(1). The ASA has been running for 223 days without issue. Today it stopped showing real time status on the Device Dashboard from within ASDM. All of the graphs state "Lost connection to Firewall."I try to manually reconnect but it will not. I have tried on a couple different computers and cannot get the monitoring connection to work.It is a very busy firewall and I will have to schedule for a restart (which I was thinking of doing) even though I do not see a memory issue as per snip below. I don't want to restart unless it is the best option.

I have a problem with ASDM connection to ASA 5520 cluster. When I'm trying to connect the ASDM shows: "Contacting the device. Please wait..." and nothing happen. The http server is enabled with default port. Both cluster members after restart.

I am creating access rule on a ASA5520 running ASA 8.2 (1) and ASDM 6.2(1) and found that the GUI has less option then when creating access rule on a ASA5505 running ASA 7.2 (3) and ASDM 5.2(3) (see attachment). Is there an option that enables me to get the same configuration options on the ASA5520 running ASA 8.2 (1) and ASDM 6.2(1) as I have on the ASA5505 running ASA 7.2 (3) and ASDM 5.2(3).

We are running a ASA5520 with system image of "disk0:/asa843-k8.bin". I'm also running ASDM ver: 6.4(7)So my question is while I'm in the ASDM on the configuration of the firewall, I'm looking at the Access Rules. When I do a show log on any of the rules that have hit counts on them, it opens up a Real-Time Log Viewer but I don't see any information. It's not showing anything, nothing appears, it just sit's there like it's waiting but no data is coming. Even though if I go back out to all the rules, I can see the hit count incrementing. The same thing happens no matter which rule I pick with hit counts on them.

we have an ASA5520 need upgrade new anyconnect client, but the new version is too big, so it's no enough space. I want to delete the ASDM image to free the more space. My question is when I delete the ASDM image,if I could manage the ASA from web browser?

I recently had a vendor configure our 2 firewalls (ASA5520). We are replacing a active-failover PIX525 firewall in 2 locations. After the vendor configured the new ASA5520's, I was unable to access the ASDM. The configurations are a basically modified versions of the config on the PIX525. I did find that they did not set the ASDM image path. [code]
I have tried from my browser as well as downloading and installing th ASDM on my computer.

I have an ASA 5520 new. I am trying to migrate from a PIX 515E. I can connect via the CLI and ASDM on the management port (IP 192.168.1.1 the default) What I am having an issue with though is when I change the management port to 10.0.1.1 via the CLI or ASDM I can no longer use ASDM. I issue the show IP command in the CLI and I see that the IP has indeed changed but I still can not get into it. I must be missing something really simple, but this is driving me insane. I want to change the IP because I need the a different interface to be 192.168.1.1.

I have an ASA 5520 running version 8.2(1) and I am having an issue with ASDM sessions.I can SSH into the ASA and have tried to clear the sessions but they do not clear as per below.
largoGW# sh asdm session0 dguselnx1 dguselnx2 dguselnx3 dguselnx4 dguselnxlargoGW# confi tlargoGW(config)# asdm disconnect 0largoGW(config)# asdm disconnect 1 largoGW(config)# asdm disconnect 2largoGW(config)# asdm disconnect 3largoGW(config)# asdm disconnect 4largoGW(config)# exitlargoGW# sh asdm session0 dguselnx1 dguselnx2 dguselnx3 dguselnx4 dguselnxlargoGW#
An interesting point: the host dguselnx is my linux based computer that I am using to SSH to the ASA. I do not connect via ASDM from this device so it is strange that the hostid for the asdm sessions is showing as my linux host and not my Windows laptop (that I am trying to connect via ASDM from).

Running ASDM V6.3 connecting to a couple of ASA5580's V8.2. After initial configuration everything seemed to work great, however, as of a few days ago I can no longer view statistical information. I can attach to the devices without a problem, view and edit all configuration information but the dashboard applets do not pull or display any statistical info. Resource, Interface, and Traffic status all time out with the error "Lost Connetion to Firewall". The syslog info is not display rather the error "Syslog Lost Connection". My first thought was a java issue on the client. I have ripped out and reinstalled even back-revisioned to no avail. I'm to the point where a dumpe of the management workstation is the next step. I'd like to avoid that extreme if possible.

Our firewall expert has gone off on long term illness leave and I am trying to pick up the pieces :-(
We have an ASA 5520 (local office) talking to another ASA (remote office) via a VPN Tunnel.
My 1st problem is that I cannot ping from my inside network (local) to the outside interface of my remote ASA.
My 2nd is that I have debug enabled on my rules but am not logging anything.

I just installed the free vpn client spotflux. The connection works fine, but after I disable the vpn again windows 7 seems to not use my "normal" ethernet connection anymore. I'm pretty sure that it will use that connection if I deinstall spotflux again but how to configure windows to use the normal connection when the vpn is not connected?I've attached a screenshot of the LAN connection settings and the priority list - but still it doesnt seem to work. What am I doing wrong?

I would like to configure an ASA5512-X in firewall transparent mode, but I am having trouble getting ASDM to lauch when I do.
I have created a BVI interface with an IP address, and I hve enabled the mangement interface, but ASDM does not lauch when I enter the IP adress of the BVI I created.
Apprently you need to use the bridge-group command to assign an interfce to a bridge group. When I enter this command at the (config-if) prompt for Management 0/0, this command is not recognized.
What are the general steps for configuring the management interface to be able to launch ASDM in transparent mode?

I would just like to to open UDP port 123 in the ASA 5510 Firewall so that our Primary Domain Controller could use this port to sync time with an external time source. We have already added an access rule for this port under the firewall configuration in ASDM 6.4 and this port was also allowed in the inbound and outbound rule of the PDC's Firewall but it seems that it was still blocked.

I have an ASA 5510 in a live environment. Up til a short while ago I could access this via the ASDM and ssh. However I can no longer connect to it via eithier. When I access It via SSH I get a disclaimer saying the following
*** You have entered a restricted zone! Authorized access only!!! Disconnect immediately if you are not authorized user! ***
It then cuts me off.
When I try to access the ASDM I get the following
The firewall is running all its services without a problem and I can ping the device without any issues. Also none of the config (to my knpowledge has been changed). I set up a console session and http server enable is still there with
http 192.168.200.0 255.255.255.0 inside

I have brought a broadband connection from a local ISP called YouBroadband. (I am from India, if you are wondering.) For the first month of my plan, I was having internet connection without any issues. But since 2nd month, I am experiencing a very strange problem. When I turn on my PC and connect to internet by entering my password, I do so without any problem. But after a few mnutes of connectivity, I loose my connection. Even stranger is the fact my Windows 7 Ultimate edition does not recognise this. It still shows connected sign in the notification area. But I am not able browse any more using any browser. to solve the problem, I start network troubleshooting, which in a few seconds shows, resetting 'Local Area Connection 2' and then I am able to log in again. At times this solution also doesn't work. All i can do at that time is shut down my PC, wait a few minutes and restart again. To my extreme dismay, this keeps happening over and over again. I connect, get disconnected, reconnect and again disconnect. This is terribly disturbing and annoying.
I have searched on Google with no success. I tried changing DNS server settings and put Google open DNS address as my preferred DNS server but that didn't solve the problem too.( I received this tip from a friend of mine.) Here's what I get when I type ipconfig/all in Command prompt-Windows IP Configuration[CODE]

I have a small network, about 35 computers.There is 20 LAN PC computers (they use dns, active directory, dhcp), and there is 10 laptops. They connect on same D-Link wireless router( radius server authentication).After most of laptops is operational(connected on wireless router and on domain ), same two laptops always disconnect, and they can't regain connection . All laptops also get their ip addresses through dhcp.I tried all kind of wireless router configuration, I don't think it is dhcp or dns server problem, remote access policy is also very simple

I have a US Robotics 5462 router and a D-Link DCM-202 cable modem on Comcast. I've had this router for years and initially configured it for wireless access using a Windows XP system (this router requires you to configure it via Ethernet and 192.168.2.1). That computer stopped working last year, so I got a new computer running Windows 7.When I first got this new PC, I could not connect to my router via Ethernet (just like I can't now), but I was still able to connect to the wireless network I had previously set up, so I was satisfied.
A year went by, and last week I was suddenly unable to access my wireless network, so I did a factory reset on the router, erasing my previously configured wireless network and requiring me to connect the router to my computer via Ethernet to reconfigure the router. I tried to do this, but despite all of the correct LEDs being lit on the router, I could not access 192.168.2.1. A little poking around on my control panel revealed that my LAN was being labeled as an "Unidentified Network" and there was "No Internet Access." I tried to make it a private network, but that didn't fix the issue.
I searched around for a while and read some advice to try running ipconfig. When I did that, I saw "Media Disconnected" for my LAN adapter. I've tried a few of the possible solutions already with no luck. With the same computer and the same Ethernet cable directly connected to my modem instead of through the router, I *CAN* get online. That's how I'm connected right now. Also, I have no problem accessing any wi-fi networks.

I have been searching forums for the last 2 hours and trying to figure out how to make this work. I tried to release/renew and it told me it couldn't and got the media disconnected message. I tried the TCP/IP and Winsock renew and that didn't work either. My internet was working OK and then all the sudden it stopped working. [code]

Running into a bit of a problem. Anytime I try to download a large file through our 5510 the download fails at different points. Cannot download via a download manger at all. I see nothing in the logs which are set to infomational.
I can connect my laptop to our internet connection outside the firewall and HTTP and download manager downloads connect and finish just fine. I go through and scrub my config for posting?

I have two asa 5520 firewalls. one at my primary data center connected to our production Internet feed, and one at my fail over data center connected to a backup internet feed. I was wondering if there was an easy way to keep the firewall rules in sync between the two firewalls. We have failover with our isp that will move our public facing address block from our primary site to our dr site in the event of a disaster so the ip addresses will not change if we were to have to fail over to the DR site. currently i just have to do any changes that i make on the fail over server but would like a way to at least simi-automat this if not fully automat this so that i can eliminate the possibility of human error of a change happening at primary but never getting don at DR.
