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,.

Why my VPN clients cannot access network drives and resources?
I have a cisco asa 5505 configured to be a VPN gateway. I can dial using the anyconnect VPN client. The remote user is assigned an IP address to my specifications. However... The remote user cannot access network such as disks in network resources or the fax server. I've done everything I can to set the right settings NAT and ACLs, but in vain. I write my config... If someone can track down the problem. It would be appreciated!

Hello
What is the IP address of the hosts/servers LAN Gateway?
If this is not the ASA 'inside' interface IP address then I assume that the problem with VPN is simply routing.
For example, if your hosts/servers LAN wireless LAN gateway router then the following would happen to your Clients VPN connections.
- Forms of customers login VPN users through configuring wireless routers static PAT (Port Forward) to interface "inside" ASA
- Client VPN sends traffic through the VPN to ASA and again the host of the server or LAN.
- Host/server LAN sees the connection from a network other than the LAN (192.168.202.0/24) and therefore to forward traffic to the default gateway that would likely be the wireless router.
- Wireless router has no route to the network 192.168.202.0/24 (VPN Pool) and therefore uses its default route to the external network to forward traffic.
- Client VPN host never received the traffic back as transmitted sound on the external network and abandoned by the ISP
So if the above assumption is correct, then you would at least need a configuration of the road on the wireless router that tells the device to transfer traffic to the network 192.168.202.0/24 to the 192.168.201.200 gateway IP address (which is the SAA)
I would like to know if the installation is as described above.

SonicWALL NSA, using VPN client overall comments to reach network of internal resources
Hello
I have problems performing Global VPN client to work when you connect to our internal network of comments in order to reach our internal LAN Server in order to reach internal resources in a safe manner. I'm not sure what could the settings were necessary in the Sonicwall to achieve?
Our installation is based on the NSA 3600 and I installed a WLAN area in the sonicwall to enable clients to connect to the internet. Traffic in the WLAN area to our internal LAN Server is denied. However, some users would like to be able to use the wireless network in order to achieve internal resources and for that I want to use the Global VPN client. It is even possible to use of an internal network from the point of view Sonicwalls Global VPN client?
The use of the outside Global VPN client works very well
Any help is greatly appreciated and if more detailed configuration information are necessary, I'll happily give you that.
Thank you
Hi Ben,
No I didn't at first, but your answers have would lead me in the right direction, hopefully. I realized that I could create a custom GroupVPN by going to the settings of the interface to the interface that is the war in the Gulf to my wireless network.

Cannot access the internal network with Cisco easy vpn client RV320
I have a cisco RV320 (firmware v1.1.1.06) and created a tunnel easy vpn (= split tunnel tunnel mode), then I installed the cisco client vpn v5.0.07.0290 in Windows 7 64 bit, I can connect to the vpn, but I do not see the other pc ping nor them, no idea?
Thank you
Hello
1. is the firewall on the active Windows 7 computer? If so, please disable it
2. can you check that you get a correct IP address in the range of the POOL of IP configured?
3. When you perform the tracert command to access an internal server, it crosses the VPN¨?
4. is the tunnel of split giving you access to internal IP subnets defined?
5. on the RV320 you see the user connected and sending and receiving bytes?
Don t forget to rate and score as correct the helpful post!
David Castro,
Kind regards

Cisco ASA 8.4 (3) remote access VPN - client connects but cannot access inside the network
I have problems to access the resources within the network when connecting with the Cisco VPN client for a version of 8.4 (3) operation of the IOS Cisco ASA 5510. I tried all new NAT 8.4 orders but cannot access the network interior. I can see traffic in newspapers when ping. I can only assume I have NAT evil or it's because the inside interface of the ASA is on the 24th of the same subnet as the network interior? Please see config below, any suggestion would be appreciated. I configured a VPN site to another in this same 5510 and it works well
Thank you

How to allow access to a local area network behind the cisco vpn client
Hi, my question is about how to allow access to a local area network behind the cisco vpn client
With the help of:
- Cisco 5500 Series Adaptive Security Appliance (ASA) that is running version 8.2 software
- Cisco VPN Client version 5.0 software
Cisco VPN client allows to inject a local routes in the routing table Cisco ASA?
Thank you.
Hi Vladimir,.
Unfortunately this is not a supported feature if you connect through the VPN Client. With VPN Client, that the VPN Client can access the VPN Client LAN host/local machine, not host from the local network to business as customer VPN is not designed for access from the local company network, but to the local corporate network.
If you want to access from your local business to your LAN network, you need to configure LAN-to-LAN tunnel.

Cisco vpn client to connect but can not access to the internal network
Hi all
I have a VPN configured on cisco 5540. My vpn was working fine, but suddenly there is a question that the cisco vpn client to connect but can not access to the internal network
Any help would be much appreciated.
Hi Samir,
I suggest that you go to the ASA and check the configuration to make sure that it complies with the requirements according to the reference below link:
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00805734ae.shtml
(The link above includes split tunneling, but this is just an option.
Please paste the output of "sh cry ipsec his" here so that we can check if phase 2 is properly trained. I would say as you go to IPSEC vpn client on your PC and check increment in packets sent and received in the window 'status '.
Let me know if this can help,
See you soon,.

Secondly, from the output of ' cry ipsec to show his ", you seem to be getting the ip address of the"jdv1.australis.net.au", not"CorpVPN"pool pool. Therefore, the No. NAT ACL on the management interface is incorrect. I would just add a greater variety of education no. NAT so that it covers all your ip pool:
access-list no.-NAT-DU-MGMT scope ip 10.10.10.0 allow 255.255.255.0 172.18.0.0 255.255.255.0
Thirdly, even with your dynamic ACL 'OUTSIDE_cryptomap_65535.65535' crypto map, it only covers the 172.18.0.32/28, so I just want to add a wider range since it seems you get the ip address of the different pool:
OUTSIDE_cryptomap_65535.65535 list of allowed ip extended access all 172.18.0.0 255.255.255.0
Then I would disable the following group of access for purposes of test first:
no access-group MANAGEMENT - OUT Interface MANAGEMENT
Finally, please clear all the SA on your ASA and xlate, then reconnect to your vpn client and test it again:
delete the ipsec cry his
clear the isa cry his
clear xlate
Please let us know how it goes after the changes. If it still doesn't work, please please send again the last configuration and also to send the output of the following:
See the isa scream his
See the ipsec scream his
and a screenshot of the page of statistics on your vpn client. Thank you.

With the help of Client VPN dial-up networking on L2l
I m tring to configure ASA 5505 with Cleint of VPN to access a remote network on a L2L with an another ASA 5505, but without success. There is a special function for this work?
Follow the topology
TKS
Hello
You must ensure that you have configured following
- permit same-security-traffic intra-interface
- This will allow VPN Client traffic to enter the ASA and leave the same interface
- If you use Split Tunnel ACL with the VPN Client, make sure that the ACL has included Remote Site network
- If you use complete Tunnel this wont be a problem
- Make sure that the ACL of VPN L2L that defines "interesting traffic" includes the pool of Client VPN on both sides of the VPN L2L
- Configure a NAT0 on the ASA of Client VPN 'outside' interface that makes NAT0 for pool of Client VPN Remote Site network
If you have a real-world setting to share I can try to help with those. Otherwise I can only give general things like the above to check.

VPN client without access to the internal network
Hi all
I try to get IPsec VPN clients talk to my internal network. Can ping the IP address of internal port, but not the bridge beyond the period of INVESTIGATION, or all the resources on the internal network.
Thoughts?
Hello Tony
You need to check on the following things
1. Split tunnel network
2. "no nat" split tunnel network
What is a network or production test (I hope that the customer have the right configuration of bridge)
Also, if possible please post your config for a better understanding
concerning

Have problems with the IPSec VPN Client and several target networks
I use an ASA 5520 8.2 (4) running.
My goal is to get a VPN client to access more than one network within the network, for example, I need VPN client IPSec and power establish tcp connections on servers to 192.168.210.x and 10.21.9.x and 10.21.3.x
I think I'm close to having this resolved, but seems to have a routing problem. Which I think is relevant include:
Net1: 192.168.210.0/32
NET2: 10.21.0.0/16
NET2 has several subnets defined VIRTUAL local network:
DeviceManagement (vlan91): 10.21.9.0/32
Servers (vlan31): 10.21.3.0/32

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.
I tried to add the following, but it does not help:
router ospf 1000
router ID - 192.168.210.1
Network 10.21.0.0 255.255.0.0 area 1
network 192.168.210.0 255.255.255.252 area 0
area 1
Can anyone help me please with this problem? There could be a bunch of superfluous things here, and if you could show me, too, I'd be very happy. If you need more information on the config, I'll be happy to provide.
Hello Kenneth,
Based on the appliance's routing table, I can see the following
C 10.21.9.0 255.255.255.0 is directly connected, DeviceManagement
C 10.21.3.0 255.255.255.0 is directly connected, servers
C 192.168.210.0 255.255.255.0 is directly connected to the inside
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
NO_NAT list of allowed ip extended access all 172.31.255.0 255.255.255.0

Dude, you point to just inside interface and 2 other subnets are on the device management interface and the interface of servers... That is the question
Now how to solve

Any other questions... Sure... Be sure to note all my answers.

VPN - PC (vpn client) problem-> router-> (site to site vpn)-> local network
Hello
is it possible to install?
I have a pc and I want to connect to the Remote LAN.
PC (using vpn client) - vpn (internet)---> ROUTER1 - a vpn (MPLS network)---> ROUTER2---> SERVER site
How can I connect to a remote server? Is there an easy way?
I did the configuration of the vpn client (I can connect ROUTER1 and access a LAN via vpn with 192.168.1.x), but I can't connect to the server, even if I set the subnet (192.168.1.x) under the access list of site to site vpn (access list for traffic that must pass between ROUTER1 and ROUTER2).
Please advise! Thanks in advance.
Looks like I've not well explained.
On ROUTER1
===================
1 ACL VNC_acl is used to split tunnel, so you should include IP server_NET it NOT vpn IP pool.
2 ACL najavorbel is used to set the lan lan traffic between ROUTER1 and ROUTER2, 2 you should inlcude
IP 192.168.133.0 allow 0.0.0.255 0.0.0.255
You must change the crypto ROUTER2 ACL of the minor or the najavorbel of the ACL
The other way to is to the client VPN NAT IP to a local area network lan IP ROUTER1, in this way, you don't need any changes on ROUTER2. But I have to take a look at your configuration to make the suggestion.
