Easy VPN with LDAP integration
Hello!
Currently I have an EASY VPN server on a Cisco 2911 with LDAP integration to authenticate the user.
Everything works well except for one aspect. When you try to connect to the VPN (IPSec Client), the user is prompted for the credentials that are in this case their domain credentials. When the user places the identification information is immediately invite you for it again and again for about 1 minute. Then their and the VPN is in place.
When I check the logs, I can't see him connect LDAP ranging down to connect to to the top.
My question is if there is a way to make the LDAP connection, stand or accelerate this process.
Thoughts?
Jason,
I had a long discussion with BU some time previously, if the LDAP protocol is in fact a taken AAA mechanism supported with ezvpn.
To which (at the time) they said 'no '.
We have therefore tabled a documentation bug:
http://Tools.Cisco.com/support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId= CSCud35798
(which has not yet been resolved).
If it is in fact always a limiting factor, I suggest contacting your system engineer or open evidence of the TAC, so we can check with BU.

Easy VPN with the Tunnel Interface virtual IPSec dynamic
Hi all
I configured easy vpn remote on a cisco 1841 and dynamic server easy vpn with virtual tunnel interface on the server (cisco 7200, 12.4.15T14)
It works with easy vpn remote to the client mode and mode network-extesión, but it doesn't seem to work when I configure mode plus network on the client of the cpe, or when I try to have TWO inside the ez crypto interfaces. On the customer's site, I see two associations of security, but on the server PE site only security SA!
Without virtual dynamic tunnel interface, dynamic map configuration is ok... This is a limitation of the virtual tunnnel dynamic interface?
Federica
If one side is DVTI and the other uses a dynamic map, it does support only 1 SA. If the two end uses DVTI or the two end uses dynamic card then it supports several SAs.
Here is the note of documentation for your reference:
Note: Multiple inside interfaces are supported only when the Cisco Easy VPN server and the Cisco Easy VPN client have the same type of Easy VPN configuration. In other words, both must use a Legacy Easy VPN configuration, or both must use a DVTI configuration.
Here's the URL:
Hope that answers your question.

Hi all
IM, configuration of a vpn for remote access with ldap, for what I see in some examples, I need to create a user/pass.
In my case, I already configured the aaa for the ldap Protocol Server. I also have the Group tunnl with the authentication server.
I need to create a user/pass?
Thank you.
Hello
I see what you mean!
It is not necessary for the integration of LDAP.
You don't have authentication LDAP not the LOCAL database, so no need for this.

Easy VPN with IPSec VPN L2L (Site - to - Site) in the same ASA 5505
Hi Experts,
We have an ASA 5505 in our environment, and currently two IPSec VPN L2L tunnels are established. But we intend to connect with VPN (Network Extension Mode) easy to another site as a customer. Is it possible to configure easy VPN configurations by keeping the currently active IPSec L2L VPN(Site-to-Site) tunnels? If not possible is there any work around?
Here's the warning we get then tried to configure the easy VPN Client.
NOCMEFW1 (config) # vpnclient enable
* Delete "nat (inside) 0 S2S - VPN"
* Detach crypto card attached to the outside interface
* Remove the tunnel groups defined by the user
* Remove the manual configuration of ISA policies
CONFLICT of CONFIG: Configuration that would prevent the Cisco Easy VPN Remo success
you
operation was detected and listed above. Please solve the
above a configuration and re - activate.
Thanks and greetings

"Dynamic crypto map must be installed on the server device.
Yes, dynamic crypto is configured on the EasyVPN server.

CIsco Anyconnect VPN with LDAP AAA
Hi there, I was hoping that someone can point me in the right direction here. I created a VPN connection profile to match anyconnect SSL entering customers. I would like to use LDAP group membership as a sine qua non for authentication. I found a few online pages on what to do about it, I followed. Unfortunately, it seems my connection profile to allow access to any user in the ldap, not only those of the ldap group database. I'll post the relevant bits of the config here in hopes that someone can point my mistake!
The idea of the config is to have the map of connections 2 by default a noaccess policy which has 0 simultaneous connections and the profile card (SSL_VPN) connection ssl to anyconnect to group_policy_SSL_VPN group policy.

Ryan,
It seems that you are facing the question where it is indicated in the section:
Problems with the help of "authentication bind first" with user-defined attribute maps:
* Then you are likely to see a failure in your authentication attempt. You will see the error message "Invalid credentials, result code = 49. The newspapers will look something like the journals below: *.
Which is the same error you see. Go ahead and replace in your attribute map and test again.
If you remove the command "bind-first authentication' configuration above, everything will work correctly.

Help with 1921 SRI Easy VPN remote w / Easy VPN Site-to-Site access
I have two 1921 ISR routers configured with easy site to site VPN. I configured VPN each ISR ACL so that all networks on each site can communicate with the private networks of the other site. I have a 1921 SRI also configured as an easy VPN server.
Problem: when a remote user connects to the easy VPN server, the user can only access private networks on the site of the VPN server. I added the IP network that is used for remote users (i.e. the Easy VPN Server IP pool) to each VPN ACL 1921, but the remote user still cannot access other sites private network via the VPN site to another and vice versa.
Problem: I also have a problem with the easy VPN server, do not place a static host route in its routing table when he established a remote connection to the remote user and provides the remote user with an IP address of the VPN server's IP pool. The VPN server does not perform this task the first time the user connects. If the user disconnects and reconnects the router VPN Server does not have the static host route in its routing table for the new IP address given on the later connection.
Any help is appreciated.
THX,
Greg
Hello Greg,.
The ASAs require the "same-security-traffic intra-interface permits" to allow through traffic but routers allow traversed by default (is there no need for equivalent command).
Therefore, VPN clients can access A LAN but can't access the Remote LAN B on the Site to Site.
You have added the pool of the VPN client to the ACL for the interesting site to Site traffic.
You must also add the Remote LAN B to the ACL of tunneling split for VPN clients (assuming you are using split tunneling).
In other words, the VPN router configuration has for customers VPN should allow remote control B LAN in the traffic that is allowed for the VPN clients.
You can check the above and do the following test:
1. try to connect to the remote VPN the B. LAN client
2. check the "sh cry ips his" for the connection of the VPN client and check if there is a surveillance society being built between the pool and Remote LAN B.

Try using the command "backup interface" on the secondary ISP interface.
http://www.Cisco.com/en/us/docs/security/ASA/asa72/command/reference/b_72.html#wp1338585
You need to increase the level of security to 1 for this interface.
By default, EasyVPN uses the highest level of safety inside and the lowest outside. Anything between the two must be set manually. I assume you have an interior vlan defined but not added to the posted config.

CANNOT ACCESS THE LAN WITH THE EASY VPN CONFIGURATION
Hello
I configured easy vpn server in cisco 1905 SRI using ccp. The router is already configured with zone based firewall. With the help of vpn client I can reach only up to the internal interface of the router, but cannot access the LAN from my company. I need to change any configuration of ZBF since it is configured as "deny everything" from outside to inside? If so that all protocols should I match? Also is there any exemption of NAT for VPN clients? Please help me! Thanks in advance.

endA few things to change:
(1) pool of IP must be a single subnet, it is not the same subnet as your subnet internal.
(2) your NAT ACL 1 must be changed to ACL extended for you can configure NAT exemption, so if your pool is reconfigured to be 10.10.10.0/24:
access-list 120 deny ip 172.17.0.0 0.0.255.255 10.10.10.0 0.0.0.255

overload of IP nat inside source list 120 interface GigabitEthernet0/1
No inside source list 1 interface GigabitEthernet0/1 ip nat overload
(3) OUT POLICY need to include VPN traffic:

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

With an interface easy VPN client only
Hi guys,.
I have an ASA 5505 configuration as simple Client VPN. Current configuration uses two interfaces: inside and outside. I tested the connection to the server and works very well.
For reasons of site specific I'm limited to a single interface, you can call it inside, lan, whatever. So I need to connect clients to the remote site behind this interface and also use it to reach the easy VPN server. Is it possible in the first place?
Of course, I will put the default route through the Interior of interface and another router will provide the Internet connection.
It's so hard to make it work you should consider the answer is no.
Specifically, you need to have one inside and outside interface or EasyVPN will not come to the top.

IOS router VPN Client (easy VPN) IPsec with Anyconnect
Hello
I would like to set up my router IOS IPsec VPN Client and connect with any connect.
Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.
I think it's possible with a Cisco ASA. But I can also do this with an IOS router?
Please let me know how if this is possible.
Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?
http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...
But I am in any way interested in using IPSec and SSL VPN on a router IOS...
It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.
The configuration guide (here) offers detailed advice and includes examples of configuration.

ACS 4.1 - LDAP integration
We want to use ACS as raduis server and use it to authenticate the VPN users
Remote access VPN user--->---> ACS v4.1---> LDAP ASA5510
ASA is already configured for the VPN, I'm a newbie with ACS. Can someone explain how to configure ACS as radius server and integrate it with LDAP.
When a user enters his user name and password, the SAA should send that ACS and ACS should compare to LDAP.
Thank you

Cisco easy VPN + loopback interface. static ip address for the client
Good day people.
I have a couple a question and answer on which I can't google for a period. BTW I maybe simly use bad aproach to choose keywords.
Thus,.
(1) is it possible to assign the same IP to the same customer every time that it authenticated, preferably without using DHCP? Definely im sure it is possible, but can't find match configuration examples (my camera's 1921 Cisco IOS 15.0.1).
(2) is it possible to assign the dynamic crypto map to the loopback interface (to make EASY VPN Server accessible through two interfaces - maybe you recommend another approach instead?) - that I move the map workingcrypto of int phy loopback - I can not connect with reason "SA Phace1 policy proposal" not accepted
Hello
(1) you can attach to the same IP to the same username using RADIUS
(2) If you have 2 outside interfaces
Then, you would use
mymap-address loop0 crypto card
int gig0/0
crypto mymap map
int g0/1
cryptp map mymap
By doing so, the local address would actually be the loop0 but Cryptography card HAS to be applied on physical output interfaces
See you soon
