Authentication by default with Peer IPSEC
Hello world
You have to understand the output below
3550SMIA # sh crypto isakmp policy
World IKE policy
Priority protection suite 50
encryption algorithm: AES - Advanced Encryption Standard (128-bit keys).
hash algorithm: Secure Hash Standard
authentication method: pre-shared Key
Diffie-Hellman group: #2 (1024 bits)
lifetime: 86400 seconds, no volume limit
Default protection suite
encryption algorithm: - Data Encryption STANDARD (56-bit keys).
hash algorithm: Secure Hash Standard
authentication method: Rivest-Shamir-Adleman Signature
Diffie-Hellman group: #1 (768 bits)
lifetime: 86400 seconds, no volume limit
For Phase 1 authentication with counterpart that makes this device use pre-shared key or the digital signature?
Also what is difference between Protection Suite and default pretection suite?
Concerning
Mahesh
Hello Manu,
I'll try to answer your question. To authenticate the phase 1 in a site to another, the two VPN peers exchange the ike policy started with the decrease in the number. Less than the higher number is the priority.
In your case if the other end is an initiator and send his game of ike policy, it will match against the IKE 50 strategy. IF it does not, then it will go to the next.
The difference between Protection suite and the default protection suite is that protection suite is your configured and default protection suite is provided with the unit.
I hope that answers your question.
Thank you
Jeet Kumar

the AAA authentication enable default group Ganymede + activate
I implement CSACS 4.0. First of all on the client, I will apply aaa authenticatio / authorization under vty. The issure if I use the followin command
the AAA authentication enable default group Ganymede + activate
What happens if I connect via the console? I need to enter a name of user and password?
Here is my configuration
AAA new-model
Group authvty of connection authentication AAA GANYMEDE + local
the AAA authentication enable default group Ganymede + activate
authvty orders 15 AAA authorization GANYMEDE + local

authorization orders 15 authvty
authvty connection accounting

accunting exec authvty
Any suggestion will be appreciated!
It should work because it is a guest message.banner whenever you try to connect (console/vty). I set it up on my router.
If you have banner motd, it will appear as well (see below). So, I have to remove it to get only the aaa banner & prompt is displayed:
************************************************************

************************************************************
Any unauthorized use is prohibited.
Enter your name here: User1
Now enter your password:

The configuration more or less looks like this:

Physically, the data is transmitted through various routers or jump to reach the destination host
But when tracing, we can see only 1 hop
Why is it so?

Client VPN with tunneling IPSEC over TCP transport does not
Hello world
Client VPN works well with tunneling IPSEC over UDP transport.
I test to see if it works when I chose the VPN client with ipsec over tcp.
Under the group policy, I disabled the IPSEC over UDP and home port 10000
But the VPN connection has failed.
What should I do to work VPN using IPSEC over TCP

Problem with tunnel IPSEC with NAT
Hello
I had an ipsec tunnel between a former Cisco router at a remote site. I'm the config 887 to an ASA migration. The remote site cannot establish the tunnel. This is the only site having problems. There are one number of other sites remote connection back without problem.
The Setup is
192.168.1.x (main site inside) - ASA - 86.x.x.x (outside) - Internet - 159.x.x.x (side remote outdoors) - Firewall - 10.10.10.x
The remote site will not accept the 192.168.1.x range so I'm NATing 192.168.50.x which is what they want to see
The config I have is
network of the NAT_TO_Remote1 object
192.168.50.0 subnet 255.255.255.0

Problem of authenticating users on L2TP over IPSec tunnel
I have a client with an old PIX-515e firewall with firmware 7.2 (4), and due to certain circumstances, I'm trying to configure L2TP over IPSec. I'm stuck at a "Error 691: the remote connection has been deinied because the user name and password combination, you have provided is not recognized, or the selected authentication protocol is not permitted on the remote access server." I have local installation of authentication for this connection, and I tried to use ms-chap-v2, chap and pap, and give the same results. I have confirmed the username and the password, but I can't after that.
The PIX, I don't see "AAA user authenticaton rejected: reason = invalid password: local database: user = tetstuser". I can still see the password unencrypted on the screen, so I can copy and paste the username and password in the appropriate fields, and I still have this error.
Does anyone have an idea where the problem lies perhaps? Thank you.
Can you please change the user as described in the doc, I shared and as indicated by the Rohan peers and share the results of the tests?
Kind regards

Secure ACS Authentication and Authorization with SecurID
I am able to authenticate connection attempts using an external database (RSA SecurID). The problem is that everyone with a token is authorized to connect on any switch with priv15 or whatever I put (but no way to control who gets what access). How can I allow users based on a certain type of belonging to a group? The SecurID server is already integrated with LDAP, it only checks to see if the user exists in the database.
I need to create two groups, or even only allow a single group and deny everyone, but anyone in the organization with a token is allowed to connect. I can't find guides who do anything beyond authentication when you use a SecurID token.
Thank you.
Hello
Have routers and switches, you given the command "authorization exec default group aaa GANYMEDE", it seems that you have only defined authentication on devices. When the control is in place, user access privileges may be governed by the ACS. In network administrator access by default policy (if you are using the default strategy for GANYMEDE), to set the authorization rule to verify membership in a user group and provide the appropriate profile of shell. Make the default rule to give DenyAccess shell profile to other users.

Authentication of Windows with ACS groups
I try to authentication of connection configuration on all of our Cisco switches. I created a group of AD Windows called NetworkAdmins and the correct users added to this group. Inside of the CSA, I did a group mapping and mapped my ACS group called NetworkAdmins to my group NetworkAdmins of Windows.
I have set up my Cisco 3750 with the following commands for authentication.
AAA new-model
AAA authentication login NetworkAdmins group Ganymede + local
AAA authorization exec NetworkAdmins group Ganymede + local
AAA accounting update newinfo
AAA accounting exec default start-stop Ganymede group.
AAA accounting update newinfo
AAA accounting exec default start-stop Ganymede group.
AAA - the id of the joint session
Authentication works, but it authenticates from any user, not just for users in the NetworkAdmins group. How can I tell the switch to authenticate only on the NetworkAdmins group?
Thanks for the help!
ACS, under your group settings to configure NAR to allow clients of the AAA. Under the default group GBA configure NAR to refuse all AAA clients (or necessary).
Hope that helps.

In your current design, I can see HSRP used to provide evacuation route VPN HA outwards. IPSec plan HA, HSRP is usually deployed when the Wan is attached Ethernet. In this case, we can build the tunnel using the virtual address HSRP giving a permanent IP address. The problem with your design, is that to reach the HSRP virtual IP address, you must cross a single hosted serial interface. If this interface is unsuccessful or if there is a problem in the path routed between cryptographic peer, you will never be able to reach the HSRP virtual IP address so the resulting solution will fail.
If it is the topology we work with, so the only recommendations I can do is to incorporate IP SLAS and followed in your design. For example, you may track the status of the interface the main router series. If the interface fails, you could decrement the HSRP interface boot priority in order to force traffic to converge on the backup router path. With star-ISAKMP KeepAlive configured on the routers in topology, routers should be able to recognize the failure and the timeout of the old SAs. Because the RADIUS is configured with two counterparts, the router can negotiae new SAs with the backup router. When the serial interface comes back online, you can have the main router anticipate waking after a delay. To detect indirect failures on the transit route, you could use ICMP IP SLA and monitoring instead. This design, however, will be properly tested for stability during the failover process.
