IPsec VPN Client - aggressive mode
Hi all
I just got got off the phone with the customer who underwent a check sweep of security from a third-party vendor. One of the vulnerebilities mentioned in the report is this:
I know that only the IPsec VPN client using aggressive mode to negotiate Phase I. So my question is how to convince my customer to continue to use the IPsec VPN? Is this what can I do to reduce the risk of the use of this type of access remotely. In addition, am I saw the same problem, if I use SSL based VPN Client?
Kind regards
Marty
Hello
Ikev1 HUB in aggressive mode sends his PSK hash in the second package as well as its public DH value.
It is indeed a weakness of slope Protocol.
To be able to act on this, U will be on the path to capture this stream in order to the brute force of the hash [which is not obvious - but not impossible.
This issue is seriously attenuated by activating XAUTH [authentication].
Xauth happens after the DH, so under encryption.
Assuming that the strong password policy is in use, it is so very very very difficult to find the right combination of username/password.
Ikev2 is much safer in this respect and this is the right way.
See you soon,.

IP address of the IPSec VPN client did not get distributed via EIGRP
We use an ASA for VPN remote access. He is running EIGRP redistribute static routes. When a client Anyconnect SSL connects, the SAA creates a static route for this client, and it gets redistributed via EIGRP. When an IPSec VPN client connects, the SAA creates a static route for this customer, but he isn't redisributed via EIGRP and so the client can not achieve anything. Why he would distribute a static created by an IPSec client?
Thank you
Have you set up IPP on dynamic Cryptography?

Function of automatic update for the IPsec VPN Client
Hello.
Do you have anyone ever tried the PIX / ASA ' feature IPsec VPN Client Auto-Update?
(see also Document ID: 105606).
He wants to make sure that I understand this right.
The user will receive a popup of information telling him to download the latest version of the client? And then there start the update itself?
If so, this would mean that the user must have the rights of full adminsitative using a laptop.
From my point of view, full administrator rights on a laptop are prohibited - 100% and therefore the functionality would be totally useless.
Anyone who can tell me whether I am good or bad?
Best
Frank
Frank,
You are right, if the computer desktop or labtop is completely locked regarding the installation of the software the customer won't be able to install it, they may be able to download from the link that you configured in ASA, once they connect to your server ASA RA but with regard to the installation user's machine needs rights profile appropriate to be able to install it.

AAA ipsec vpn clients how to see the history of connection on asdm or asa5510
Hello all, I would like to know how see history of connection ipsec vpn client users, they authenticate to the local aaa, not in active directory. I am able to see the current logon session. go to monitoring\vpn\vpn statistics\sessions, this shows me sessions underway, but I would like to see for example the connections client vpn for the last month. I did some research and saw the info on aaa Server? I checked that article and does not see what I was looking for.
It's actually a called (NPS) network policy server microsoft radius server.
The one I used (ACS 5 and ACS 5) who was just an example.
You can review the below listed doc

How do I allow IPSec VPN client-to-client

Hello
Can someone tell me whatthe above message means and how to solve it.
Thank you
The command to disable connections inbound aggressive mode.
If you want, there is an option to disable connections inbound aggressive mode on the tunnel-group as well.
tunnel-group ipsec-attributes xxxxxx
ISAKMP am - disable
In this way you disable connections inbound aggressive mode to a specific peer.
If a peer tries to establish a connection in aggressive mode, you should see a message like this in the logs:
"Unable to initiate or respond to fashion aggressive while disabled"
This command prevents Easy VPN Virtual Private Network (easy) clients to connect if they use of pre-shared keys because the easy VPN (hardware and software) customers use aggressive mode.

Need urgent help in the configuration of the Client VPN IPSec Site with crossed on Cisco ASA5510 - 8.2 (1).
Here is the presentation:
There are two leased lines for Internet access - a route 1.1.1.1 and 2.2.2.2, the latter being the default Standard, old East for backup.
I was able to configure the Client VPN IPSec Site
(1) with access to the outside so that the internal network (172.16.0.0/24) behind the asa
(2) with Split tunnel with simultaneous assess internal LAN and Internet on the outside.
But I was not able to make the tradiotional model Hairpinng to work in this scenario.
I followed every possible suggestions made on this subject in many topics of Discussion but still no luck. Can someone help me here please?

Adding dynamic NAT for 192.168.150.0/24 on the external interface works, or works the sysopt connection permit VPN
Please tell what to do here, to pin all of the traffic Internet from VPN Clients.
That is, that I need clients connected via VPN tunnel, when connected to the internet, should have their addresses IP NAT'ted against the address of outside internet2 network 2.2.2.2 interface, as it happens for the customers of Campus (172.16.0.0/16)
I am well aware of all involved in here, so please be elaborative in your answers. Please let me know if you need more information about this configuration to respond to my request.
Thank you & best regards
MAXS
Hello
If possible, I'd like to see that a TCP connection attempt (e.g. http://www.google.com) in the ASDM logging of the VPN Client when you set up the dynamic NAT for the VPN Pool also.
I'll try also the command "packet - trace" on the SAA, while the VPN Client is connected to the ASA.
The command format is
packet-tracer intput tcp
That should tell what the SAA for this kind of package entering its "input" interface
Still can not see something wrong with the configuration (other than the statement of "nat" missing Dynamics PAT)

RV180 and Cisco IPSec VPN client
Hi NetPro,
RV180 router supports VPN client using the regular Cisco VPN client connections?
Data sheet says it works with client QuickVPN. If the regular non-Quick client is not supported, both clients can coexist (= be installed simultaneously) on the same PC?
Is supported customer QuickVPN split tunneling?
Thank you!
Lubomir
Lubomir Hello,
The RV180 currently supports QuickVPN and PPTP VPN connections. It also has the IPSec tunnel as well, but it does not support the Cisco VPN client.
I saw a question have Cisco VPN and the QuickVPN installed on the same computer.
The QuickVPN client supports only split tunneling.
I hope that answers your questions.

UC500 and IPsec VPN client - disconnects
Just throw a question out there.
I have a UC560 running uc500-advipservicesk9 - mz.151 - 2.T2 site HQ. Remote users, about 8 of them, attempt to connect via IPsec VPN (v5.0.07.0440) HQ clients to access files, etc.. The behavior I see is 5 users to connect successfully, but only 5. As soon as more users trying to connect, they have either:- connect with success for a minutes, then unmold
- get a 412, remote peer is not responding
- connect, but someone of another session kickoff.
Users use the same VPN profile, but with names of single user and passwords.

JP,
An update of IOS is worth it, even if him debugs seems to indicate that there is a problem with the client. If possible, I always suggest test with another client to see if it is unique to the Cisco VPN Client on Win7. Regarding the limit of 20 tunnel, it is very probably the number of IPsec security associations. If you issue a 'show crypto eli', this example displays the number of Sessions that are currently active IPSec.
HTH,
Frank

When a user establishes a VPN connection, their local routing tables have routes through the tunnel to the 10.21.0.0/16 and the 192.168.210.0/32.
They are only able to communicate with the network 192.168.210.0/32, however.

And you try to connect to the 3 of them.
Politics of Split tunnel is very good, the VPN configuration is fine
The problem is here

Remote IPSec VPN - client Windows 7 and ASA 5505
Hello
I'm having trouble with configuring IPSec VPN with Cisco ASA 5505 and Windows 7 client native VPN remotely. My client PC Gets the VPN IP pool address and can access a remote network behind ASA, but then I lose my internet connection. I read that this should be a problem with the split tunneling, but I did as it says here and no luck.
Windows VPN Client settings, if I uncheck "use default gateway on remote network" I have an internet connection (given that the customer is using a local gateway), but then I can't ping remote network.
In the log, I see the warnings of this type:
TCP connection of disassembly 256 for outside:192.168.150.1/49562 to outside:213.199.181.90/80 duration 0: 00:00 0 stream bytes is a loopback (cisco)
I have attached my configuration file (without configuring split tunneling, I tried). If you need additional newspapers, I'll send them right away.
Thank you for your help.
Petar Koraca
That's what you would have needed on versions 8.3 and earlier versions:
permit same-security-traffic intra-interface
Global 1 interface (outside)
NAT (outside) 1 192.168.150.0 255.255.255.0
However I see that you are running 8.4 so I think that all you need is this (I never did on 8.4 so it may not be accurate)
permit same-security-traffic intra-interface
network of the NETWORK_OBJ_192.168.150.0_24 object
dynamic NAT interface (outdoors, outdoor)
Give it a shot and let me know how it goes.

ASA static IP Addressing for IPSec VPN Client
Hello guys.
I use a Cisco ASA 5540 with version 8.4.I need to assign a static IP address to a VPN client. I saw in the documentation Cisco that this can be done to validate the user against the local ASA and in the user account database, you assign a dedicated IP address, or using the vpn-framed-ip-address CLI command.The problem is that the customer never gets this address and it always gets one of the pool in the political group. If I delete this pool, the client can't get any address.No idea on how to fix this or how can I give this static IP address to a specific VPN client?Thank you.Your welcome please check the response as correct and mark.
See you soon

Hello
I set up a lab for RA VPN with a version of the ASA5510 8.2 and VPN Client 5 software using digital certificates with Microsoft CA on a Windows 2003 server. I did the configuration based on this document from Cisco's Web site:

Do I have to use a model of different web registration for application for a certificate instead of the user model? How can I determine the OU on the user certificate so that match tunnel-group?
Please help me!
Kind regards

You can use the group certificate mapping feature to map to a specific group.
This is the configuration for your reference guide:
http://www.Cisco.com/en/us/partner/docs/security/ASA/asa82/configuration/guide/IKE.html#wp1053978
And here is the command for "map of crypto ca certificate": reference
http://www.Cisco.com/en/us/docs/security/ASA/asa80/command/reference/C5.html#wp2186685
Hope that helps.
