Our ASA 5510 can provide VPN to our LAN cloud?
Hi people,
We have a number of (1 7 or if virtual, dedicated) servers hosted in a cloud provider well known on the West coast of the USA.
They just put an ASA5510 across our LAN Server to help protect the servers.
I was wondering if it is possible that the ASA5510 can provide VPN access to our LAN cloud? At the moment we have the firewall block - all - ports except 80/443/3389 (RDP for our Windows servers).
I was actually hoping to block port 3389, so nobody can RDP on all servers. BUT... VPN in our LAN cloud, then we can connect to a server via RDP or any software / port. Indeed, the VPN opens all ports... you have created a VPN tunnel has provided
So is this possible? The ASA5510 this offer?
Last question-> and it's a ballast: gulp:...
We cannot install any client software 3rd party... including any cisco vpn client software. We must use the built in software Windows7 VPN... making PPTP, SSTP, L2TP-IPSEC.
So... now the ASA5510 can offer that? If so... is there any special scripts or configs I need to give to the Cloud hosting provider, so they can set the machine to work?
Help, please!
-Jussy-
Two possibilities come to mind.
-Built-in L2tp over Ipsec client.
ASA config Guide:
http://www.Cisco.com/en/us/docs/security/ASA/asa82/configuration/guide/l2tp_ips.html
-Clientless webvpn (if RDP and other plugins, but requires java/activeX for some features...
http://www.Cisco.com/en/us/docs/security/ASA/asa82/configuration/guide/WebVPN.html
These options should work except ASA is in mode multi-conext.

ASA 5510 can be configured as bridge mode and always send Netflow information to a collector
ASA 5510 can be configured as bridge mode and always send Netflow information to a collector?
We have a PIX connect internal network to the internet. Because PIX does not support NetFlow, as temporary solution, we thought to a 5510 ASA between the PIX and the internet gateway and configure as a bridge so that there will be no problem routing, and the SAA can always send Netflow information to a collector.
Can someone please advise if this is possible?
Thank you.
I have not tried, but as a Netflow service policy should work in routed and transparent mode. Reference.
Why don't you just replace the Pix with the ASA in routed mode?

Cisco ASA 5510 - restrictions of VPN (AnyConnect) based on the AD user or IP address
Hello
I want to test how to restrict access user on an ASA 5510 AnyConnect. In politics, I can define what networks will go through the VPN tunnel and which not (split tunneling). The ASA has a LDAP connection and only AD users with a special security group can connect over AnyConnect.
On the other hand I would like to restrict access for special users within a VPN policy.So my question:
What are your recommendations to implement this szenario?My two ideas would be:
1. the access rules based on the user of the AD.
2. special reserve IP addresses in the pool of addresses AnyConnect for some users, so I can limit access to the normal firewall rules base based on the source IP address.What are your recommendations and is it possible to realize my ideas (and how)?
Thanks in advance
Best regards
Hello
I will suggest that you configure a second ad group in the server and another group strategy in the ASA, you can configure certain access on each group policy "the installer of the filters, assign different split political tunnel, different ACL' and in the ad server, you can assign users for example to the AD Group A and AD Group B based on the access you want to give them now , you must configure LDAP mapping to assign the user specific group policy that you want based on the AD group that they belong.
You can follow this documentation that will help you configure the LDAP Mapping:

Between asa 5510 and router VPN
Hello
I configured ASA 5510 to vpn LAN to LAN with router 17 857. and between the routers.
between vpn routers works very well.
from the local network behind the ASA I can ping the computers behind routers.
but computers behind routers, I cannot ping PSC behind ASA.
I have configured the remote access with vpn cisco 4.X client, it works well with routers, but cannot work with asa.
the asa is connected to the wan via zoom router (adsl)
Are you telnet in the firewall?
Follow these steps to display the debug output:
monitor terminal
farm forestry monitor 7 (type this config mode)
Otherwise if its console, do "logging console 7'.
can do
Debug crypto ISAKMP
Debug crypto ipsec
and then generate a ping from one device to the back of the ASA having 192.168.200.0 address towards one of the VPN subnets... and then paste the result here

Hi all
I have a VPN of n-star with 5510 boxes in several places.
Users complaining that s2s links are beat from time to time for both places.
Here's the log output for the moments where the links are torn down:
First spoke:
07/07/2010-20:17:09 Local4.Notice
% 713259-5-ASA: group = , IP = , Session is to be demolished. Reason: The user has requested

I have HIS lifitime for 24h\4Gb to each ASA and the volume of traffic or time never pass in this case, KeepAlive is enabled to the ASA hub as well. I see a number or a "spacing" all day with the same reasons for termination that I presented above. Anyone has a suggestion or idea why s2s VPN are hinged and how make them more stable even if the traffic is not flowing throughout.
Thanks in advance.
Sergey,
No matter how lucky you have vpn time-out configured on one of the sides (it may be in default group policy perhaps?) (see the race from all political group | I vpn)

With the help of ASA 5510 L2L and VPN L2TP
I would let my remote users access to all resources bhind the ASA and my remote branches.
Here's my setup. ASA5510 as a hub to the data center.

In the logs ASDM, it shows that I get some QM WSF Errorsand on the Windows XP computer, I get an error 789. I put the pre-shared on the XP machine as a result and another j.4 measures.I am quite new to the method of L2TP VPN, I've always used Windows Server for the VPN and now I am to find out why. In any case, I'm sure I'm missing some info that is needed to diagnose, but here's a copy of my config.
I hope someone can point me in the right direction to understand this because I am pulling my hair out!

Split DNS on ASA 5510 access remote vpn works not
I connect successfully to the tunnel and can ping hosts remotely by IP but am unable to browse the internet from the VPN client. Also, the resolution of host name on the remote end does not work... can only connect through the IP address. Ideas? Thanks again!
Your group policy will SUFFER a good split tunneling and divide the dns settings. But I think that you are awarded the DfltGrpPolicy rather than your group policy will SUFFER because group policy is not set in your group of tunnel, nor be transmitted from authentication.
Make a vpn-sessiondb distance 'show' to confirm what group policy is assigned to fix it, assign your group policy will BE to your group of tunnel as follows:
global-tunnel-group attributes
Will BE by default-group-policy

ASA with several L2L VPN Dynamics
I have an ASA 5510 such as VPN, used for about 30 L2L - VPN concentrator.
I need also some VPN L2L with dynamic peer remote.
While the configuration for a single dyn - VPN is quite simple (as described in several examples), how can I configure the ASA in the case of many dyn - VPN?
Basically, all the VPN - dyn must use the same PSK (the DefaultL2LGroup).
But using the "aggressive" on the remote peer mode, I could use a different PSK for every dyn - VPN:
tunnel-group ipsec-attributes ABCD
pre-shared-key *.
This configuration is correct?
Best regards
Claudio
Hello
Maybe the solutions provided in the following document may also be an option to configure multiple dynamic VPN L2L connections on the SAA

Help with a VPN tunnel between ASA 5510 and Juniper SSG20
Hello
We have a customer wanting to configure a VPN Site to Site tunnel between a new purchased 5510 of ASA located in his direction with its Juniper SSG20 Office, located in the main office. We contacted HP and they send us a Cisco professional to do the job.
After 2 days from 16:00 to 22:00 and error and countless hours of research online and nunerous calls, we are still unable to get traffic from the network of agencies to enter the tunnel.
Main branch
1.1.1.2 1.1.1.1
----- -----------
192.168.8.0/24 | ASA|-----------------------------------| Juniper | 192.168.1.0/24
----- -----------
192.168.8.254 192.168.1.254According to Cisco professionals, the tunnel is now in place but no traffic through. We are unable to ping anything on the network on the other side (192.168.1.0/24). We receive timeout ping all the time. The Cisco professional told us it's a routing or NAT problem and he's working on a solution!
Through research, I came across a post on Experts-Exchange (here) [the 1st comment on the original post] which States "...". that both sides of the VPN must have a different class of LAN for the VPN to work... " Would that be our problem?
It has become a critical issue to the point that he had to replace the Cisco ASA with a temporary Juniper SSG5 on another subnet (192.168.7.0/24) to get the tunnel upward and through traffic until the ASA VPN issue is resolved and I didn't need to say that the client is killing us!
Help is very appreciated.
Thank you
1. Yes, ping package from the interface of the ASA is considered valuable traffic to the LAN of Juniper.
SAA, need you traffic from the interface source ASA's private, because interesting to determine by crypto ACL MYLIST traffic between 192.168.8.0/24 and 192.168.1.0/24.
You will also need to add the following configuration to be able to get the ping of the interface of the ASA:
management-private access
To initiate the ping of the private interface ASA:
ping 192.168.1.254 private
2. the default time before the next generation of new key is normally 28800 seconds, and if there is no interesting traffic flowing between 2 subnets, he'll tear the VPN tunnel down. As soon as there is interesting traffic, the VPN tunnel will be built automatically into the next generation of new key. However, if there is traffic before generating a new key, the new tunnel will be established, and VPN tunnel will remain standing and continue encrypt and decrypt traffic.
Currently, your configuration has been defined with ITS lifetime of 3600 seconds GOLD / 4608000 kilobytes of traffic before the next generate a new key (it will be either 3600 seconds, or 4608000 kilobytes period expires first). You can certainly change it by default to 28800 seconds without configuring kilobytes. SA life is negotiated between the ASA and Juniper, and whatever is the lowest value will be used.
Hope that helps.

Unable to connect to server vpn behind ASA 5510 with windows clients
Hi all
I've seen a number of posts on this and followed by a few documents of support on this issue, but I'm totally stuck now, nothing seems to work for me.
This is the usual scenario, I have a VPN windows 2003 Server sat on the lan deprived of our ASA 5510 firewall, and I try to get my Windows XP / 7 laptop computers to connect to it.
Within the ASDM:
(1) Server Public created for Protocol 1723
(2) Public created for the GRE protocol Server
3) created two public servers have the same public and private addresses
(4) the foregoing has created config Public Private static route in the section NAT firewall
(5) rules to Firewall 2 also created above on the external interface for both 1723 and GRE
When you try to connect, I get the following entry in the debug log.
6 August 6, 2010 17:09:37 302013 195.74.141.2 1045 1723 ChamberVPN-internal built ride connection TCP 1889195 for outside:195.74.141.2/1045 (195.74.141.2/1045) to the inside: ChamberVPN-internal/1723 (XXX.XXX.XXX.XXX/1723)
but nothing else.
The server shows not attempting a connection so I think I'm missing something on the firewall now.
Also inside interface there is a temporary rule:
Source: no
Destination: any
Service: IP
Action: enabled
This should allow all outbound traffic only as far as I know...
Any help would be greatly appreciated.

Hi Chris,
ASA newspaper indicates that the connection is interrupted because of "syn timeout. This means that asa receives no response from the Windows Server. Right now, we need to clarify some points.
1 - your vpn server committed a correct default gateway error or the path that lies in your fw interface asa.
is 2 - possible to start capturing packets on Windows Server. Hereby, we can get data flow information beetween client and server. And we can be sure that Windows Server wonders vpn.

WiFi comments at the Public VPN (ASA-5510)
Hello
I have an ASA 5510, that has the following configuration:
interface Ethernet0/0
nameif outside
security-level 0
address IP 1.1.1.1 255.255.255.240 (fake IP for obvious reasons)
interface Ethernet0/1
nameif inside
security-level 100
IP 192.168.0.200:ABCD 255.255.0.0
interface Ethernet0/2
nameif comments
security-level 100
IP 10.10.10.1 255.255.0.0
Global 1 interface (outside)
NAT (inside) 0 access-list sheep
NAT (inside) 1 0.0.0.0 0.0.0.0
NAT (guest) 0 access-list sheep
NAT (guest) 1 0.0.0.0 0.0.0.0
-------------------------------
What I do for a client (eth0/2) Wifi comments access to our VPN configured on the external interface? It is a Cisco AnyConnect VPN installation using the mobile client. As it is, they identify the DNS since the WAP and try to connect to "vpn.mysite.com", which resolves itself into the public IP (interface) outside my ASA.
When I was asked first to authorize this change, I thought it would be a simple NAT rule but I think I'm missing something that I can't get this to work.
Thank you
They are not capable of VPN for the external interface of the IP address of the guest network because it is by design not permitted.
They need to connect to the IP comments to be able to VPN to ASA comments network, and you will need to activate AnyConnect on the interface of comments as well. "vpn.mysite.com" would then need to resolve the IP comments when they are connected via the comments interface.

Hi all.
I search the internet to find a way or all first, whether it is possible to do what I want to do, but I can't find anything corresponding to what I'm looking for. Possible that I don't have the right keyword.
We change our old Pix 515e this weekend and for any new ASA 5510.
With this new facility, I want to implement Radius Authentication for the user remote vpn. Change the firewall of the company is an important factor and for the first phase, the user will keep authenticate locally but I need that in phase 2, they will be authenticated through a radius server.
Is there a way to configure both user authentication remote vpn?
For example.
All users will be authenticated locally unless the service member COMPUTER that is authenticated by the radius to the testing server.
I have remote vpn users anywhere in the world if I don't want these users are blocked by the radius authentication test. What I want is that users in Group1 will be authenticated locally on the SAA and users in group2 will be authenticated by the RADIUS. During the test will be done, all users will gradually transfer for radius authentication.
Is it possible
Thank you

Hi Jonathan,.
The best way to go about this would be that you set up another group strategy & corresponding tunnel group named Test and set up Radius Authentication for VPN group using the link below: -.
Ones you have done test and feel confident, you can change the type of authentication for the Production Group. The reverse could be implemented double authentication as RADIUS and if it does not use local but personally I'll put up a group of test and then those I am confident, that I'll change the strategy of Production Group to use the Radius Server to auth.

Smartphones blackBerry delayed Voice Mail Alerts BlackBerry Storm 9550
For about a month I received Voice Mail alert hours, days, or sometimes not at all (and find that several messages rates graft in VM). I don't know if it's a matter of BlackBerry, or if I need to contact Verizon Wireless. It seems to happen when I'm
