Cisco Firewall :: Setup NAT With ASDM On ASA 5520 For A Client?
Sep 15, 2011
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.

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.

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 .

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) ?

I need to setup an ASA 5520 to correctly NAT over two wan links. The idea sounds pretty straingforward but it does not, I have only 2 IPs that are involved with the NAT
192.168.1.10(Nated Server) -- 172.16.1.10(Web Server)
I have 2 interfaces that sould be applied to it let's say outside1, outside2. The server is reacheable through each outside interface, the outside interfaces is selected uppon dynamic routing and that is working OK.
So if link outside1 is up the Nat follows this schema 192.168.1.10(inside) -- 172.16.1.10(outside1)
that works fine, but I want that automagically changes over when the link outside1 is down to 192.168.1.10(inside) -- 172.16.1.10(outside2).I know I can't have a NAT with 2 IPs and 2 different interfaces (ASDM doesn't allow me to), is there a way to implement this??

I am working on IPSec Passthrough on an ASA 5520, with version 8.3, and ASDM 6.3. Currently I have a requirement for users in my internal network (10.10.249.128 / 25) to be able to connect to external IPSec VPN servers.
So I created a network object with 10.10.249.128 / 25, and used dynamic PAT to translate the source ip address to the external internet facing outside interface:
I then added the following rules on the inside-in ACL: However troubleshooting shows that isakmp is passing through the firewall, but esp and ah is not.
For isakmp:
For ESP:Seems like the nat rule is drawing my ESP traffic,

I am trying to setup an active/standby failover with 5520's running 8.4(2) and am having problems with it not dropping connections during the failover. I am using a portchannel from the switch to each ASA and using sub-interfaces off that. I'm using the command Failover mac address Port-Channel1 “mac-address on primary Port-Channel1” “mac-address on standby Port-Channel1”.The command goes through but doing a show interface port-channel1 doesn't show a change in the mac address on the secondary unit after a failover when it becomes active.

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 am trying to configure a client profile under the Any Connect Client Profile tab in the ASDM but keep getting an error message stating "Check that you have a proper Any Connect package installed in the Any Connect Client Software menu. Also check that your ASDM username have enough privilege." My user has sufficient privilege but I am not sure which Any Connect software I should have to enable this. Right now I have anyconnect-win-3.0.10055-k9.pkg installed. This is a lab setup using GNS3.

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).

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.

Im sure this has been asked before but a quick search has not yielded any exact results so here goes
I have anyconnect up and working great on for vpn users using local authentication. Im going over the white papers and seeing a lot of options for NT domain, LDAP, tacacs+ etc
we would like remote vpn users to autherticate using their windows domain password, but Im not sure which would be the easiest and quickest option to configure, and I cant find a guide for asdm setup for this topic that doesnt cause more questions than answers . The white papers Im finding are confusing since I am a rookie at this topic.
what is the easiest/quickest way to setup windows domain authentication via asdm?

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 configured my ASA5520 to act as VPN server. It accepts connections from the internet and then it authenticates the user to a Windows 2008 Server via Radius.Everything works fine if I use the VPN client embedded in Microsoft Windows. Conversely, if I try to configure Cisco VPN Client, I cannot find where to define the PSK string.

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?

I have remote branches that connect to the corporate office as a site-to-site VPN. Now the clients at the branch are getting an application that is using an unsecured port (tcp/23). I would like to use a set of ASA 5520's that I have at the corporate office, with the AnyConnect license on them. I want the client machines to establish a tunnel from the client to one of these ASA's. The ASA' then would have a connection to the VLAN that the receiving server is housed on. The trick is to just establish the tunnel from the client to the ASA that will allow the IP of the client to not be translated. So I would use the ASA as a security 'pass-through' for the clients that use this new application.

We have an ASA with software version 8.2(1) and ASDM 6.2 to use the VPN. We configure the anyconnect client with split tunnels for our vendors to access internal server and have access to the other resources in the web simultaneously. Windows XP client works fine however, the Mac OS x can only access the internal resource but not the web.we need to restrict the client to access and use only specific IP and http port.have internal and external DNS that are separated by ASA5520s all VPN terminate at the DMZ with192.168.xx.0/24 IP pool?
