Cisco VPN :: ASA 5520 - ASDM Shows Lot Of IPsec VPN Sessions In GUI
Jan 20, 2013
I have upgraded my ASA 5520 til version 9.1 with ASDM version 7.1. After the upgrade ASDM shows a lot of IPSEC VPN-sessions in the GUI that i cannot see from the ASA. Right now the GUI says that I have 28 IPSEC-sessions while the output from "show vpn-sessiondb l2l" shows the expected 4 tunnels and the output from "show vpn-sessiopndb remote" shows 0 as expected. (I do not use IPSEC from remote users).

We have asa 5520 with 8.4(2) release and asdm 6.4(5). When we create new ipsec connection profiles (by ipsec wizard for example), ASA reset all vpnclients sessions active. Now we need to create new profiles, but we have 170 vpnclients sessions active, so we cant'.

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).

On our ASA 5510 we have two security contexts. After opening ASDM I can see and manage admin context, but cannot see second context. I can do changes to second context via CLI but as probably you know it's easier and quicker doing it via ASDM.

In our organization ,recently we are facing a issue with VPN connections are disconnecting abruptly in reandom time periods ( 5Min,15Min,1Hr also).We have verified in our SysLog .[code] The same was worked well in Cisco Pix 515E Firewall ,After changed to Cisco ASA 5520,it is giving the issue.- All Ports are allowed for outbound traffic with a Source Network 172.16.40.0/24 to their Client VPN.- This issue is giving for other Subnet Users i.e 172.16.33.0/24 to their Cleint VPN sessions & I allowed all Ports for them for Outbound traffic. Any feature in ASA is casuing for terminating the sessions which was not in Cisco PIX 515E.- ASA version is 8.0.

I have setup ipsec VPN in my C2811 router but when "show crypto isakmp/ipsec sa" shows nothing. Remote end point is an "ASA5520". Does it indicates that the remote ASA5520 not yet configured?

We are running ASA5520 with version 8.4(2)8 software and ASDM 6.4(5)205.We have noticed the following problems:When having more than 30 IPSec,sessions connected, the log fills up with errors "System is low on free memory blocks of size...", When filtering by "AnyConnect Client" in "Monitoring > VPN > VPN Statistics > Sessions" the values "Bytes Tx / Bytes Rx" column is presented in one line ie. "8450198968129194". Seems to be missing a <cr><lf>,When uploading a new CSD-image (via ASDM) all configuration för GPO, CP, DAP seems to dissapear, though, the config seems ok when looking at a sh run. Also, the newly updated csd-image doesn't show i ASDM.

I have an ASA Firewall 5520 and to add or edit configuration, I use the ASDM interface. For some reason, the admin password that I use is no longer working. The last time I logged on to the firewall was last week and I am the only person with access to it. I used a backup account to login and was able to, but on the menu bar the "Configuration" button is missing.

I have 2 ASA5520's in failover pair.After failing over I cannot run ADSM on the secondary (now active device), I get "unable to launch device manager from [primary address]"
I can ASDM to the primary device (now marked as "standby ready") on the failover address. I can SSH to it also.I CANNOT ASDM to the secondary device (now marked as "active") on the primary address. I CAN SSH to it.
When I run "sh asdm image" I get valid output (asdm image disk0:/asdm-645.bin) on both.However when I run "sh ver" on each it appears ASDM is not running on the secondary device :
Cisco Adaptive Security Appliance Software Version xxxx [only]
Compared with :
Cisco Adaptive Security Appliance Software Version xxxx
Device Manager Version 6.4(5)
It appears as though ASDM is only running on the primary device (regardless of the fact it is now in standby mode). Is this normal?
I am having to run in a failover condition due to a intermittent hardware fault on the primary unit but require access to the ASDM for monitoring/diag purposes during this condition.

i have a new ASA 5520 with only factory default settings. I ran the commands below on the CLI as instructed for a Cisco document but i cannot access it via https://192.168.1.1/admin like it says i should be able to.
Step 1 To identify the IP addresses from which the security appliance accepts HTTPS connections, enter the following command for each address or subnet:
#hostname(config)# http source_IP_address mask source_interface

I have a problem with my ASDM Logging(ASA5520, System image file is "disk0:/asa804-k8.bin").If i generate any traffic, the ASDM do not show the packets correctly. For example, if i generate a icmp traffic from interface inside to outsite, the ASDM does not show the packets, when it shows it apperars just in one direction.

We have a pair of ASA running 8.0 (old) version. The way we create outbound rules is done through ASDM and when we need to open outbound connections to a server in the internet, we create named object with IP address configured manually.But practically , this doesnt work, since the server is a server name which can resolve to multiple addresses. Everytime the server chagnes its IP the ASA rule needs to be updated.Is there a difference if we add rules through CMD prompt as against ASDM where we need to enter IP addresses?

We’ve got lot of ASA appliances (around 30, 5505/5510/5520) and we never had this problem since the use of the new image software ASA 8.4(1) and ASDM 6.4(1). So, my problem is located on two ASA 5520 with active/passive failover with ASA image 8.4(1) and ASDM image 6.4(1).
My problem is that our appliance doesn’t show any logs when an ACL deny a packet, even if when I specify a specific “deny ACL” with a specific logging condition, asdm and ssh buffer logging are empty but the counters of the ACL increment.

I want to setup NAT with ASDM on ASA for a client and I can not make it work. I have several interface:
Inside: 10.97.0.1 / 24
Outside: 10.0.1.70 /24
Interco: 192.168.6.1 /24
Other Sites: 10.26.0.4 /24
All routing in the network is Ok My customer want to access a server @ ip 10.194.70.1 in https on the interface Interco with his nat address as 10.97.0.11 .This server must be accessible with the address 10.97.0.11:443 from interfaces inside, outside and other sites.And source address must be nated with original destination address 10.97.0.11 to be redirected on 10.194.70.1.

yesterday I tried to connect to our ASA 5520 using ASDM Launcher, which has alwasy worked before. For some reason ASDM Launcher is no longer working from both my Win XP desktop and Win XP laptop. I can open ASDM through the browser but not the launcher. Both desktop and laptop have Java 7 U 6. I'm not sure if I can back rev my Java.

When trying to access the asa (8.0(3)) with asdm the console send follwing error message:
vPif_isVpifNumValid: pifNum out of range!
vPif_getVpif: bad vPifNum(0xa6) from 87EBC81 from 83833B4
Have a strong suspicion that it is a hardware failure (since asdm has worked and have tried to restart the box) can not see any errors with any show commands, but could it be a RAM error .

Currently running a pair of 5520 as VPN routers. running 8.0.3, been using only Anyconnect SSL VPN for end users. These boxes do nothing else except serve VPN clients.However, recently we tried testing some IPSEC clients and are realizing that the Anyconnect SSL VPN clients is about 10x slower than the IPSEC client.From my house, downloading either CIFS or FTP, I can pull pretty close to 1.0mbps, while using Anyconnect, I pull 0.1mbps. What could be causing this slowdown? Should SSL VPN performance be on par with IPSEC? Clients all are windows 7, 64 bit. and the testing is being conducted on the same device.

The network design is a hub and spoke using a carrier provided MPLS network with a ASA 5520 at the hub that has a IPSec tunnel to another part of the company.This configuration has worked for sometime now (long before I came to the company a couple of months ago).The thing that does not make sense to me is that the those networks out on the spokes did not have a route to the inside interface network of the ASA. With the way this MPLS works, if a network is not in the MPLS network routing tables it will not pass that network. The network was not in the MPLS network, nor was it in any of our edge routers connecting to the MPLS.
These hub networks did have routes both in the MPLS and edge devices for the networks on the other side of the IPSec tunnel and have been reaching them for some time.So what I am trying to understand is how it is possible for these hosts that have no route to the ASA inside interface network, but do have routes to the remote networks, how are they able to successfully pass that traffic? There are no NAT devices between these WAN hosts and the ASA.

I have a client that uses the ASA 5520 as both a firewall and VPN termination device. Day to day VPN usage is 30-50 users and the memory (512 MB) is typically at 50% while the CPU is mostly under 30%. I've suggested the RAM be upgrade to 1GB.The client would like to add a large block of VPN users which could see 250-300 concurrent users. What kind of a system resource hit should the expect with this level of load?

I have made the following change to my ASA 5520 using ASDM to try and force VPN clients to use a self assigned certificate from the ASA. I made the following changes Remove Access VPN > Certificate Management > Identity Certificates > Add Certificate.Then I made the following change.. Remote Access VPN > Network (Client) Access > IPSec(IKEv1) Connection Profiles > Connection Profile > Edit > IKE Peer Authentication > Pre Shared key and pointed the identity certificate to the one I created in the step above.Having made this change I am still able to VPN without a certificate configured in authentication settings.I was expecting that the VPN would attempt to issue the self assigned cert to client machine?

Options a user may reside in Austin, TX and I want the user to utilize the local proxy (i.e. texasproxy:8080). We currently only require the user to enter the RSA passcode and username to authentication (RSA/AD username are identical). Is there a way to have the user authenticate via RSA and have the user's AD group membership (TX) assign the user the specific IE proxy settings? We are utilizing an ASA 5520 on 8.2, but we are willing to upgrade to newer IOS or even consider anyconnect to resolve this issue.

Currently we are having a 2 ISP for Internet. Need to achieve redundancy for IPSEC VPN using the domain.
Requirement :Will configure a domain and assign two public IP address from 2 service providers. Will set the priority for the public ip address and do the manual change during the ISP failure.We will provide the domain name to the clients to setup the IPSEC VPN.So incase of failure by one ISP, we will change the priority in the domain to point to the availble address.So that we can reduce the downtime and no need of configuring new IPSEC VPN tunnels.
Question :Whether we can achieve this in Cisco ASA 5520.Or do we have an alternate solution to overceome this solution.

Here is the situation: A CISCO871 router is configured to establish an IP SEC tunnel with a CISCO ASA5520. The configuration is OK about that. I wish to configure the same CISCO871 in order to establish a LAN-to-LAN IP sec Tunnel with another CISCO871 at the same time in order to reach private network. So, I have followed the Cisco procedure Document ID: 71462 "LAN-to-LAN IP sec Tunnel Between Two Routers Configuration Example"; it works, I can reach the peer private network BUT ONLY when the IP SEC tunnel with ASA is not established.
It seems to be a routing problem...I don't find how to configure to make both tunnels up and functional at the same time.

I'm encountering what I think is an issue on logging system on FW ASA 5520 - Asa Version 8.4(2), ASDM version 6.4(5). When I disabled the logging inside a rule from ASDM, or from console with the "log disable" option inside ACL, If I check in ASDM logging real time window I continue to see all the entry related to disabled rules. This is a correct behaviour about ASA logging ? How I can "hide" the entry related to disabled rules (this is what I need for troubleshooting purposes) ?
