CISCO ASA Enable DNS Lookup Problem

I have Cisco ASA 5510 , from ASA CLI i can not resolved the hostname. ( cisco.com or google.com)
At many form say do this.
1. Whilst in enable mode > enter configure terminal mode, then enable DNS Lookups.
CiscoASA#conf t
CiscoASA(config)# dns domain-lookup Outside
2. Then specify the external DNS Servers (Change IP addresses appropriately).
CiscoASA(config)# dns server-group DefaultDNS
CiscoASA(config-dns-server-group)# name-server 122.122.122.199
CiscoASA(config-dns-server-group)# name-server 122.122.122.198
CiscoASA(config-dns-server-group)# exit
3. Test it by pinging a name/URL.
CiscoASA(config)# ping www.20best.blogspot.com
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 123.123.123.123, timeout is 2 seconds:
But there is no command ( dns server-group ) in my ASA
Please tell me how to do this or any way
My ASA is showing only

Dear Jennifer,
From Router-ISP, I check it is resolving the name to IP
but from ASA 5510 not, it giving error

Cisco ASA 5505 Reset-I Problem with TCP State Bypass

Hello,
I have a Cisco ASA 5505 that functions as my primary firewall and a Mitel 5000 controller behind it. I have two external phone users that have been connecting through the firewall with no issues for six months until about two weeks ago. I am now seeing the following log entry on the phone trying to connect to the Mitel Controller.

My phones are designed to work with the Mitel 5000 and Mitel 3300 phone controllers. The 5000 will only use port 6800 for call control, while the 3300 will use 6801 (Secured Minet), 6802 (Minet SSH), and if those fail, port 6800 (Minet Unsecured). When the phones initiate a connection, they try 6801 first. If 6801 is unavailable, the phone controller adds the RST flag to the ACK packet. When the phone sees the RST flag, it is supposed to reset and use the next port (6802). The same process happens again for port 6802, then the phone knows to try 6800. The problem is that the ASA sees the RST flag now and terminates the connection at the firewall. Therefore, the phones never see the RST flag, and continue to try the connection with port 6801.
I have tried to use the TCP State Bypass feature to correct the situation, but the log shows that the connection is still being terminated immediately by the firewall. I am a novice when it comes to configuring the ASA. Any help would be greatly appreciated, as the company that I bought the phone system from is out of troubleshooting options. I do not think that I have made any changes to the firewall around this time. I have packet captures and logs from my ASA and I have wireshark data on the inside of my network. I need to figure out how to configure the ASA so that it ignores the RST flag and sends the packet back to the source.
Any help would be greatly appreciated!

Thanks Rizwan,
Still no luck. I can't even ping the otherside (office).. I am not sure if i'm running the debug rightway. Here are my results...

Cisco ASA Enable Password

Hey,
I am trying to change the enable password on cisco ASA 5510. I run enable password <password>. I log off, and log back in with my username/password and type en, it asks for a password and enter the password that I just set but it does not work.
what am I missing?
Thanks

Are you using the local user database or a TACACS or RADIUS server to authenticate?
If using a TACACS or RADIUS server enter your user password when you type enable. If that doesn't work disconnect the TACACS or RADIUS server and try to enter the enable password you created.
If using the local user database, are you sure that you are entering the password correctly? Perhaps you typed it incorrectly when creating it and accidentally put a space at the begining or end?
If non of the above work then you will need to perform a password recovery:
Reboot your ASA
Press the Esc key to enter ROMON mode when prompted
Change the configuration register value to 0x41 by using the command confreg 0x41
To tell the ASA to ignor the startup configuration issue the command confreg
     Current Configuration Register: 0x00000041
     Configuration Summary:
       boot default image from Flash
       ignore system configuration
     Do you wish to change this configuration? y/n [n]: y
    5. At the prompt enter Y
    6. Accept all default values when prompted
    7. Reload the ASA by enter the command boot
    8. When prompted enter enable and leave the password blank
    9. Issue the command copy start run
10. Enter configuration mode configure terminal
11. Enter the command no config-register (the value is returned to its default value of 0x1)
12. Save your configuration copy run start

Cisco ASA and DNS

We purchased a bunch of Cisco ASA 5505 for our branch offices. Offices are made up of less than 20 end points. We are using it as a firewall and DHCP server at hte moment but also assumed that it had DNS server capabilities. Basically use it as a SOHO router. My research thus far indicates that yes we can use the device as a dns server but it won't resolve locally defined hosts. So it can relay dns request to an external dns server but won't allow me to configured an a record on the device itself.
Can anyone verify this before I look into purchasing another device just to do local DNS server services?
Thanks!

Joe
As far as i know the ASA cannot act as a DNS server nor can it act as a DNS relay. What you can do is -
1) configure DNS servers on the ASA that can be used in certain situations for allowing the ASA to resolve a name to an IP. For example using the Botnet filter on the ASA, SSL certificates etc. require the ASA to be able to qurey external DNS servers.
But this is for use by the ASA itself ie. it is used to resolve names within the ASA config. It is not used to allow clients to ask the ASA to resolve DNS names for them. So it can neither act as a DNS server itself nor can it pass on clients DNS queries to DNS servers.
2) if you use the ASA to hand out IPs via DHCP you can add valid DNS servers within the DHCP config just as you can with Windows DHCP.

Cisco ASA Active standby failover problem

We have configured ASA Active standby failover with ASA5505 . When primary unit power off, secondary unit became active. when primary unit power on, then primary unit is becoming active again. i think for active standby setup there is no preemption. The real issue is when primary ASA became active after power on all the external connectivity getting down. Please see the below config,

I don't think this will ever work!
So far I know you can access the InitialDirContext only if you deploy your application on application server as J2EE application.

For anyone who is experiencing slow DNS lookups...

I finally worked out what was wrong with my network config last night and thought I'd share it with everyone in a simgle post in the hope it'll help someone else.
I tried the BIND work around, but it wasn't all that much faster.
I tried disabling IPv6, but that didn't do much...
The solution?
In 'System Preferences' -> 'Network'
Go to configure the adaptor (Airport / Ethernet / etc)
In 'DNS Servers' where you'd normally specify the DNS servers given to you by your ISP... don't do this! As crazy as it sounds don't
Of course, if you're using newer routers you'd not be having this slow DNS lookup problem and specifying the ISPs DNS Servers would be appropriate... still
What you want to specify here is your ROUTER's IP:
eg. 192.168.0.1
With this simple modifcation you'll be fine. Why? You ask?
In Linux / OSX (I imagine in Unix as well) the way the lookups are carried out are different from Windows. I have other Windows computers on our network and they never had DNS lookup problems and they've been given the ISPs DNS IPs... anyway I think I'm talking out of my depth now heh.
This works!
Remember: Specify your router as the DNS Server!

I've had this problem on a G4 PowerMac running Panther, and it still had it after a Tiger upgrade. I just replaced it with a Core Duo MacMini, 10.4.7, same problem of slow DNS lookups (i.e., slow initial start to loading a web page, then it goes quickly). Windows machines on the same subnet have no such problem. I've tried the various suggestions on various forums, none of which worked. I tried:
- turn off IPv6 (no help)
- directly enter my ISPs DNS servers (no help)
- manually configure both IP and DNS (no help, went back to DHCP)
- swear at the computer (a little help, mentally)
After some more reading, I tried resolving some addresses using the host command from the Terminal:
host -v www.apple.com 24.34.240.9
where the IP address is one of the DNS servers for my ISP (Comcast). I got a no server found message! I then tried the second DNS server in the Comcast list (found from my router), also no server found. Tried the third one in Comcast's list of DNS servers, and it worked. Entered it in System Preferences -> Network as a DNS server, and now web browsing is zippy! I verified that the two DNS servers that MacOS couldn't see are also down as far as Windows was concerned (using the nslookup command in windows).
What this tells me is that the OS X algorithm for handling unreachable or slow DNS servers is different from that in Windows. Maybe Windows remembers a bad experience with a DNS server and uses ones that it has success with, while OS X just keeps trying them in order, slowing timing them out until it finds one that works?
This could also explain many of the puzzling symptoms people have been seeing (things work some times, other times not; some people have luck specifying the DNS server manually, others don't). It all depends on what DNS servers got distributed to the Mac via DHCP, and how far down the list you have to go to find one that is responsive.
Anyone reading this forum with technical knowledge of both UNIX and Windows DNS lookup implementations? Is there some way to tweak in MacOS to make it perform more like Windows in this situation (like, maybe shortening the DNS server failure timeout)?

DNS Lookup Timeout Problems with Cisco SA520w

Hello,
We are trying to configure our new Cisco SA520w with our Internet connection.
As soon as we replace our existing Linksys RV042 with the Cisco SA520w, we find that DNS lookups start to take longer and longer to resovle. For example, an nslookup against yahoo.com will timeout, or take 10-12 seconds. Web browser requests simillarly take 30-45 seconds to resolve.
We've tried using both Google's and OpenDNS servers, as well as our ISP's nameservers. In all cases, the long DNS resolution takes place.
At first we thought that the firewall was misconfigured. However, we removed all firwall rules, and continued to experience the problem.
We've tried checking and unchecking the DNSProxy checkbox, but this doesn't seem to have any noticeable impact.
Does anyone have any idea about which setting impact DNS looksups, or what else we might try to troubleshoot this issue?
Thanks,
Chris

Regarding the question on 5-10 days for product support to become active, I followed up with the CA team and received the following, which is good for All partners to know...
Below is a description of the primary cause of delays in contract registration.
Contract registration takes 24-48hrs. Delays are generally caused by the Reseller/Partner who doesn't provide the product serial numbers to Cisco when they purchase the service. The contract cannot be registered until the Reseller or the Disti provides the serial numbers to Cisco via SMS3 (or B2B). In cases where Disti doesn't have a mechanism to collect the serial number before the product is shipped, or in cases of drop-ship, the Distis often have to track down their Resellers to get the serial numbers to Cisco.
There is a new program being discussed (drawing board now, so not available today) which will to allow the end-user to register the contract themselves, thus eliminating the need for the Disti or the Reseller to collect the serial number an input it into SMS3.
But in any case (now or later), when a customer calls in for support, if their contract has not yet been registered, the SBSC can work with the Global Entitlement Team to look-up the contract via the PO or SO number and complete the registration so service can be provided.
Hope this helps...

VPN PROBLEM CISCO ASA 5505

    Hello, I have been trying to configure a VPN with Cisco Asa 5505 and Cisco VPN client 5.X for 3 weeks and I am not being able to accomplish it, so I decided to reset to factory defaults and start over again.
     I used ASDM 6.4 VPN wizard to configure it (I selected exempt local network from NAT and enabled split tunneling, but I have tried other combinations as well).
     Tunnel seems to be established properly since I do see an endpoint while using 'sh crypto isakmp sa' but 'sh crypto ipsec sa' shows no packets encrypted or decrypted, so VPN is not working as expected. I can't ping or rdp to internal LAN:

Thank you very much for your help

Yes, it was a VPN client problem. I was doing test with a WWAN card and it seems it is not compatible with windows 7.
• The VPN Client on Windows 7 does not support WWAN devices (also called wireless data cards).
I should have read Release Notes before. Thank you very much for your help and effort.

Remote Access VPN on Cisco ASA Problem

Hi, i configured Remote access VPN on Cisco ASA 8.x as per below configuration.
Problem is that my internet has stopped working, and default route is just showing stars.
i can ping internal server 10.110.10.150 fine , which i allowed on VPN ACL, but my other traffic not going to regular internet on my laptop,
what additional required to force my internet to go to regular internet instead of getting encrypted?
Also attaching output of route print at the point when VPN is connected.

Firewall Cisco ASA 5505 new interface license problem

Hi
I have one ASA 5505 with a Base License
The problem is when i want to use a new named interface the system says "With current License maximum number of named interfaces allowed is 3. Name cannot be set for this interface"
And the question is if with this base license the interface cannot be used or only cannot be named?

Hi,
The ASA5505 has with Base License the limitation of 3 Vlan interface of which 1 is also limited in access (shown by the above output mentioning DMZ Restricted)
For an interface on the ASA to operate it must have a name with the command "nameif"
If you already have 3 Vlan interfaces in use then with this license you wont be able to configure 4th Vlan interface without getting a license that supports more interfaces. I guess that would be the Security Plus license.
I know that this has come as a surprise to several users that have posted here on the forums. I too think that its a needles "feature" in the ASA to limit the use of the device in such a way.

Cisco ASA 5505 Site to Site VPN Problem

Hi All,
We have a site to site VPN with a cisco asa 5505 on one end and a Checkpoint firewall on the other end.
We can establish the vpn tunnel and all users in the remote office are working great. However at a random point during the day or it may even be after 2 weeks of working, the tunnel between the sites automatically fails.
When I dial into the modem which is connected to the firewall I see the following messages in the logs:
Sep 14 2011 16:40:02: %ASA-3-713902: Group = *.*.*.*, IP = *.*.*.*, QM FSM error (P2 struct &0x42314d8, mess id 0xa18dcb12)!

There is nothing in the Checkpoint logs. To solve the issue I have to reload the firewall.
I have checked both firewalls for any mis-matched parameters and do not see any.
Any help is very much appreciated as it is very frustrating for myself and the users in the remote office.
Thanks!

Also to note, PFS is enabled on both firewalls. Config on Cisco ASA firewall as follows:

Hi,
I would suggest sharing the firewall configuration (except for any sensitive information they might have) so troubleshooting this would be easier.
It would seem to me that during your "packet-tracer" test there is already an existing traffic flow through the ASA with the same information that you entered in the command.
I don't know however why the connection would be blocked according to the "packet-tracer". In my own test this seemed to work. Output was otherwise the same but the "connection" wasnt dropped.

DNS Resolution in Cisco ASA 5525

Hey all,
I will begin by telling you what my end goal is, I am trying to block specific websites on our cisco ASA 5525 using FDQN. I know that this functionality for DNS resolution was not implemented until a specific version.
Current Version: Cisco ASA 5525
ASA Version: 8.6(1)
I can ping external addresses from the ASA however I cannot ping hostnames like "ping google.ca" does not work.
What I've done.
dns domain-lookup inside
dns domain-lookup outside
name-server x.x.x.x (Primary internal dns server)
name-server x.x.x.x (Secondary internal dns server)
name-server 8.8.8.8 (Google external dns server)
name-server 8.8.4.4 (Google external dns server)
domain-name example.com
With this config I can, however, ping hostnames of internal servers.
This is an example of me pinging an external hostname.
ciscoasa# ping google.ca
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2607:f8b0:4009:803::101f, timeout is 2 seconds:
No route to host 2607:f8b0:4009:803::101f
Success rate is 0 percent (0/1)
Any ideas?
Thanks!

officeasa# ping www.google.com
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2607:f8b0:4009:802::1012, timeout is 2 seconds:
No route to host 2607:f8b0:4009:802::1012
Success rate is 0 percent (0/1)
John, due to the sensitive nature displayed within show route output, is there any other information I can tell you, what exactly did you need to see from this information?
(I know without certain information you cannot help but I need to ensure security on my end)
Thanks for understanding.

DNS lookup behaviour of cisco devices

Hi All,
Does anyone know how routers and ASA's deal with dns lookups for hostnames in their configuration?
For instance, an NTP server (0.pool.ntp.org), or a hostname in a VPN tunnel configuration.
I get the impression that there is only a 1 time resolve happening.
Can anyone confirm this and if this is the case, does anyone know how to modify this behaviour....
Thanks in advance.

Hi,
Cisco routers can be set up as proxy-dns but with a lot of limitations but ASA can't so on the ASA you must enter static host commands which stay indefinitely.
I don' t know if it's possible to tune the cache timeout and what is the default value.
Here is the link descibing the caveats for IOS:
