a peer has dynamic IP - Site to site VPN - ASA5540
I need to configure a site to site VPN. One of the peer has dynamic IP address. The peer host name is qpmmoroc.dyndns.org. I am able to ping between the firewall, but how do I set the perr by using host name
Unfortunately not a supported configuration. You need to configure dynamic to static LAN-to-LAN tunnel according to the example configuration next:
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00805733df.shtml
VPN tunnel can only be initiated at the end of dynamics.

When you work in Firefox, is there a way to open a new window with a site when the House on Firefox setting has several Web sites?
Firefox always opens a new window with the home page (s), you must use shift + left click on a link (bookmark) to open a page in a new window or just rip an existing tab by dragging the tab slightly downwards to open the tab in a new window.

MSN Outlook, hotmail "IE has blocked this site to display content with security certificate errors. Click here for options... »
How can I get rid of this irritating pop-up message whenever outlook is open?
Without knowing what are certificate errors, it is a shot-in-the-dark.
80 90% of certificate in Windows XP errors can be attributed to one of the following two issues:
- Time Date, time, time zone, or light of day on your computer is/is not set correctly. The time on your machine should be within 5 minutes of real time for certificates authenticate properly. Right-click on your taskbar clock, and select time settings to check the correct time. Synchronize time via Internet can solve this problem.
- Windows XP does a poor job of keeping its root certificates (certificates by which all other certificates are considered) up-to-date. The newer versions of Windows did a much better job. It certainly wouldn't hurt to update your root certificates and in many cases, this is all you need. For update, visit the following article:
"Members of the certificate program root Windows.
<>http://support.Microsoft.com/kb/931125 >
Then go down to the subsection titled "root Update Package (for Windows XP only). Then click on the option "update for root certificates for Windows XP... "the link. This will take you to the last downloadable update. Download the package on your computer and double-click it to update your certificates
One of the above should solve your problem.

VPN site-to-site between 3 dynamic ip site to ip address static site
Hi all
I have a scenario,
I have a static ip address in the headquarters and I have 4 office locations of all offices of construction site have dynamic ip.
I created a site to site vpn between HO perfect work for 1 site office
but I create a second profile in HO ASA for site office 2 config, I have created does not work.
I use HO ASA 5520 and branches 5505 all site offices is ADSL connection
I enclose my config HO
Can u sat down just how dynamic config several profile in the HO
Thank you
Zeus
It's just a suggestion...
You want to get 3 dynamic sites connected with the HO, right?
HO:
As the branch have dynamic ip, you must use the DefaultL2LGroup profile (the same shared key for all three BO).
The crypto-plan should be dynamic with the right soure/destination NET configured. Exempt NAT with the same source/destination NET as well.
BO:
Configured as a VPN Site-2-Site normal with the HO. The IPSEC Wizard is very useful.
To connect to HO Bo, the branch must initiate the tunnel. After that, you have 2 full functional site site VPN.
Welcome,
Norbert

My laptop is a Dell Vostro 1720 of 32 bits, and so I accept I can't upgrade my Muse more away, but which has hosted a site for me, what should I do to add another site?
Hello
What I understand, that is, you already have a free site hosted with Adobe Business catalyst, and now you want to get a more.
To do so, publish a Muse Adobe Business catalyst site.
Access to the administration panel and go to settings-> Site Management site, you should see the upgrade option, you will pay for the site, because it is not a free site.
Let me know if you have any questions, or if I have missed something

Site to Site VPN using an interface to Peer and LAN
Hello
I have an ASA 5580 to the site to site VPN with our partner. VPN connection is through my external interface and Local for the VPN network comes from the external interface too. Is it possible to do? Thank you.
The layout you describe is contrary to the concept of basic firewall of the approved facility and no approved interfaces (upper and lower security level).
If your LAN is on the external interface, which is to stop remote users simply access it directly?

Site to site VPN tunnel - cannot ping the second interface of the firewall peer inside2
I have two ASA 5505 firewall each with a basic license: FWa and FWb. currently there is a VPN tunnel between them work. I added a second (inside2) interface to the firewall, FWb, but I can't ping firewall FWa, so that I can ping the inside interface of FWa.
I can ping the FWb inside interface 192.168.20.1 from the FWa inside 172.16.1.1 interface, but I can not ping to the 10.52.100.10 of the FWa FWb inside2 interface. I can not ping the gateway host FWa 10.52.100.1.

Hi odelaporte2,
Is very probably the "access management" command is not applied in the second inside, only inside primary (see the race management) which will confirm.
This command can be applied to an interface at a time, for example, if the law is now applied to the inside, it can not be applied to the inside2 at the same time.
It may be useful

You try to run a Site to site VPN and remote VPN from the same IP remotely
We currently have a site to site VPN configuration between our offices call center and a 3rd party that allows them to access our training to their employees to use environment while being trained on our systems. This tunnel is running between our ASA and their ASA without problem; However, when we have managers come out to the call center, they are unable to use remote VPN to access our office.
Apparently the same IP peer remote that we use for our site to the other tunnel is the same IP that our managers use to access the internet when they are on-site with the customer. When I look at the logs it shows the VPN attempt and then I get treatment Information Exchange has failed. So from what I can understand when our managers are trying to connect to our firewall from the same IP address as the counterpart of site to site it automatically tries to create a tunnel, according to the information of the site to the other tunnel. If our managers are anywhere else, they can connect through remote VPN with no problems.
My question is if anyone knows of a way to make the firewall allow VPN site to site and remote connections with the same remote IP address.
Hi John,.
Basically, in older versions, when you hit a static encryption card and you does not match this static encryption completely map the connection continues until the dynamic encryption card. For this reason, you can connect your IPSec clients before. A bug has been opened on this vulnerability.
CSCuc75090 Details of bug
The crypto IPSec Security Association are created by dynamic crypto map to static peers
Symptom:
When a static VPN peer adds all traffic to the ACL crypto, a surveillance society is based even if the pair IP is not allowed in the acl to the main façade encryption. Are these SA finally put in correspondence and commissioning the dynamic crypto map instance.
Conditions:
It was a planned design since the first day that allowed customers to fall through in the case of static crypto map did not provide a necessary cryptographic services.
The SA must be made from a peer configured statically and a dynamic crypto map instance must be configured on the receiving end.
Workaround solution:
N/A
Some possible workarounds are:
Configure a static nat device when you try to use the remote VPN if the firewall remotely will be hit with a different public IP address. It would be a good solution, but it will depend on how many ip addresses public you have available, if you really want one of these ip addresses for that access.
Also, I thought you could use AnyConnect instead of the IPSec VPN client. I don't know how many users need to connect from your PC to the remote site, but the ASA has 2 licenses SSL available that you could use. Because Anyconnect uses the SSL protocol, it won't have a problem on your environment.
Below some information:
Hope this helps,
Luis.

First shot at the site to site VPN fails
This is my first attempt at establishing a VPN site-to site on ASA 5505 s. Fortunately, I'm able to do on the bench and not on the real sites. As soon as I can verify connectivity, I'll move them to the physical sites.
The two ASAs are running 8.3 (1). I tried with ASDM and I tried via CLI. I don't seem to be able to do anyway.
An ASA is configured with the address of WAN 10.1.52.1/24, address LAN 192.168.52.1. Another ASA is set up 10.1.200.1/24 WAN, LAN 192.168.200.1. Because they are on the bench (lab / whatever) there is a single cable connects the two WAN ports. I have a single workstation on each LAN to test connectivity. I CAN'T successfully ping the WAN ASA (10.1.52.1) from the workstation on 192.168.200.1 and vice versa. I'm NOT able to ping the workstation on 192.168.200.1 or of the ASA 10.1.200.1 (192.168.52.1) LAN and vice versa.
Here are the configs for the two and some recording of debug output:

Match your configuration with my setup and make changes. Filters VPN are not allowed because you are not filtering anything. Remove the filter VPN at both ends, and then try to ping through the VPN. Also if you ping forms inside the interface inside the interface of the other device, and then make sure that access management is enabled on both interfaces, it will not respond to ping requests.
How to check if access to administration are enabled or not is by running the command:
See the human race
If you get anything enter command 'inside man' and then run ping.
Let me know if it helps.

IPSec site to site VPN cisco VPN client routing problem and
Hello
I'm really stuck with the configuration of ipsec site to site vpn (hub to spoke, multiple rays) with cisco vpn remote client access to this vpn.
The problem is with remote access - cisco vpn client access - I can communicate with hub lan - but I need also communication of all lans speaks of the cisco vpn client.
There are on the shelves, there is no material used cisco - routers DLINK.
Someone told me that it is possible to use NAT to translate remote access IP-lan-HUB customers and thus allow communication - but I'm unable to set up and operate.
Can someone help me please?
Thank you
Peter

How the DLINK has been configured for traffic between the site to site VPN subnets? You are able to add multiple remote subnets on DLINK? If you can, then you must add the pool of Client VPN subnet.
Alternatively, if you cannot add multiple subnet on DLINK router, you can change the pool of Client VPN 192.168.6.0/24, and on the crypto ACL between the site to site VPN, you must edit the 180 existing ACL
DE:
access-list 180 allow ip 192.168.7.0 0.0.0.255 192.168.1.0 0.0.0.255
access-list 180 allow ip 192.168.200.0 0.0.0.255 192.168.1.0 0.0.0.255
TO:
access-list 180 allow ip 192.168.6.0 0.0.1.255 192.168.1.0 0.0.0.255
Also change the ACL 190 split tunnel:
DE:
access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.200.0 0.0.0.255
access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.200.0 0.0.0.255
TO:
access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.6.0 0.0.0.255
access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.6.0 0.0.0.255
Finally, replace the remote subnet 192.168.7.0/255.255.255.0 192.168.6.0/255.255.254.0 DLINK.
Hope that helps.

Site to Site VPN problem ASA 5505
Hello
I have a strange problem with a site to site VPN. I configured it completely and I added 3 of my internal networks to be encrypted and access the remote network across the tunnel.
For some reason, I can access the remote network of only two of the three internal networkls that I've specified.
Here is a copy of my config - if anyone has any info I would be happy of course.
Thank you
Kevin

Hello
I have created a new site to site vpn connection and can't know why it does not work.
All other VPN site-to-site work properly. The news, the problem is MATCHJLS. Could anyone recommend measures to correct?

Hello
OK, given the above information, I would say that the VPN L2L your part should probably be fine for traffic you are trying with the packet - trace.
It seems that you get no traffic back from the remote end
This could mean one of the following things
- Remote site may not login either in their VPN appliance, firewall or the firewall of the real server (which I doubt since were talking about web service)
- Remote site has not configured routing properly for your source IP address / network. For example, your connection attempt can reach the remote server, but the return traffic could get transferred to the wrong place on the remote site. It is more likely when the remote end manages Internet traffic and VPN traffic on separate devices
- Remote site has not activated the service on the real server (which is still little provided this isn't a service only serve on the server you through this VPN L2L)
- etc.
As I said look it seems so VPN L2L is fine. Its place and running, but you can't get traffic back on the L2L VPN that suggest that the problem is at the remote site.
If you go ask about this since the admins of the remote site, let us know how to do the thing.
If you found this information useful, please note the answer/answers and naturally ask more if necessary

Troubleshooting IPSec Site to Site VPN between ASA and 1841
Hi all
in the past I've implemented several VPN connections between the devices of the SAA. So I thought a site link between an ASA site and 1841 would be easier... But it seems I was mistaken.
I configured a VPN Site to Site, as it has been described in the Document ID: SDM 110198: IPsec Site to Site VPN between ASA/PIX and an example of IOS Router Configuration (I have not used SDM but CCP).
I have run the wizards on the ASA with ASDM and the current IOS version 15.1 1841, with CCP.
It seems to Phase 1 and 2 are coming although my ASA in ADSM reports (monitoring > VPN > VPN statistics > Sessions) a tunnel established with some of the Tx traffic but 0 Rx traffic),
On the ASA:

It seems that the routing on the 1841 is working properly as I can tear down the tunnel and relaunch in scathing a host on the network of 1841, but not vice versa.
Trounleshoot VPN of the 1841 report shows a message like "the following sources are forwarded through the interface card crypto. (172.20.2.0 1) go to "Configure-> routing" and correct the routing table.
I have not found an error on the 1841 config so if one of the guys reading this thread has an idea I appreciate highly suspicion!
It's the running of the 1841 configuration

Joerg,
ASA receives not all VPN packages because IOS does not send anything.
Try to send packets to the 1841 LAN to LAN of the ASA and see is the "sh cry ips its" on the 1841 increments the encrypted packets (there not)
The problem seems so on the side of the router.
I think that is a routing problem, but you only have one default gateway (no other channels on the router).
The ACL 100 is set to encrypt the traffic between the two subnets.
It seems that the ACL 101 is also bypassing NAT for VPN traffic.
Follow these steps:
Try running traffic of LAN router inside IP (source of ping 192.168.37.x 172.20.2.254) and see if the packages are not through the translation and obtaining encrypted.
I would also like to delete 100 ACL from the inside interface on the router because it is used for the VPN. You can create an another ACL to apply to the interface.
Federico.
