Cisco VPN :: AnyConnect And MSChap-V2 On Microsoft Radius With ASA5510?
May 13, 2013
We have a Cisco ASA5510 configured to work with Microsoft Radius Server. VPN authorization and authentication is working well with L2TP over IPSec, and users are authenticating with MSChapV2 like we want them to.
Now we are trying to setup Anyconnnect to do the same. How do we tell AnyConnect to use MSChap-V2 versus PAP? using ADSM? I think I know how to do the Microsoft Part of it, but I don't know where to go in ADSM to configure this.
I'm running WCS 7.0.220.0.I would like to authenticate users that are able to logon the WCS, through MS Network Policy Service (RADIUS).I would like all my domain users to be member of the local group on the WCS "Lobby Ambassador", so all domain users has access to generate guest access accounts, for the web auth... I can see under the WCS Administration under AAA that it should be able to use RADIUS - but i'm not sure how to setup the NPS policy?
I have a Cisco C1140 Ap. I have cnfigured the device. Initially for testing i used WPA and authenticated locally. I have now setup a radius server and added my AP in as a client etc. I have changed my SSID's to authenticate with the radius server and i am having issues authenticating.I can connect via a PC and an iphone. They say that i am connected but i get no ip address and the debugs.
I bought 2 Cisco 1140 series Access Points a couple of months ago. We would like to use PEAP to autheticate with Microsoft IAS Radius Server & Active directory. I cannot find a document which describes how to setup this type of configuration. The only document which is close is how to setup LEAP & with ACS: [URL] I initially followed the 'TechReplublic's Ultimate Guide to Enterprise Wireless LAN Security' which has all the steps to setup Radius server, client side configuration, Certificates and finally a handy excel script to generate a config for the AP. This did not work. [URL] I am now trying to configure the AP using the Web GUI. I can see the network on the client machine but when I try to connect it timesout.
I ve configures an asa 5505 for remote vpn with anyconnect. it works just fíne - from remote i can ping the Clients and Server inside, i can do RDP or Connect via SSH to any machine, map some volumes local and so on but: I can not connect microsoft sql server. It uses port 1433 for the first connect and establishes then a dynamic connection. So i am a Newbie - what rules or configs do i miss?
Need deployed accounting method to log Anyconnect session details ? Do you do it via a radius server or via logging messages to a syslog server ?
Any appropriate configuration ? I am looking to log successful and unsuccessful authentications as well as session length, log on and log off times.
I've been playing around with Anyconnect authenticating to AD via ACS 5.1 but can't seem to get the accounting details I require. Similarly I have tried to catch appropriate syslog messages but again without much success.
Is it possible to send profile name as an Radius atribute during client authentication? I would like to match users depends on profile name to sperate Identity Stores in my ACS. ASA 5540 8.4, anyconnect 3.1.01065, ACS 5.1
I have been successfully able to setup Cisco AnyConnect VPN on ASA 5520 with 8.4 code. I have set it to authenticate against the RADIUS Server (Microsoft Windows 2008 NPS server). I have noticed one thing, on the server under "Constraints and Authentication Method". I picked MS-CHAP-v2, but it is considered Less secure authentication methods. I can click on Add and choose other Authentication methods like Smart Card or other Certificate, PEAP, EAP-MSCHAP v2. I picked PEAP but then the VPN does not work.
So first of all does it really matter if I just leave it to MS-CHAP-v2? Because from my understanding is that AnyConnect will authenticate to ASA and then ASA in the backend talks to the RADIUS server so from a security stand point this scenario shouldn't it be sufficient as no un encrypted or less secure information is available to the outside world? Secondly is there any documentation on using PEAP with Cisco AnyConnect?
We are in the process of upgrading our win2003 radius server with a new win2008 radius server. We have an ASA5520 and FWSM in 6509, using anyconnect client. This has worked fine until we introduced the win2008 radius server. When in the asdm on the asa, you can click on the new server and click test and authenticate ok with your AD credentials. But when try to use anyconnect on your laptop, it takes the credentials password and the accept certificate, but then fails with "anyconnect was not able to connect to specified gateway.." message, then "the secure gateway has rejected the connection attempt due to network connectivity issue...host or network is 0" message. We thought we setup the new radius the same way, obviously not. is therw an easy way to use debug on the firewalls to see what is wrong? looked in event logs on radius server, have not found anything.
I am setting up a clientless SSL VPN and AnyConnect on a ASA5510 running 8.4. When I login to clientless SSL VPN I get a menu with AnyConnect showing as an option. When I click on that AnyConnect it try to load. Half way loading an error message pop up.Error message:The secure gateway has rejected the connection attempt. A new connection attempt to the same or another secure gateway is needed, which requires re-authentication. The following message was received from the secure gateway: No address available for SVC connection.When I load AnyConnect seperately then it works. I don't have that problem when using 8.2.
I have a small issue with the AnyConnect client. Under Windows XP, I was able to accept and install the certificate from the firewall and get a vpn connection working. But under Windows 7, I have to accept the certificate everytime I conect. Is there a reason for that?

We have an ASA5510 with the Anyconnect Essentials license. I'm in the process of setting up Anyconnect and immediately run into a question. We have a /29 subnet setup and AFAIK i must use the outside interface address for Anyconnect. However i already have an https service PAT forward on this address. So, can i setup Anyconnect to listen on eg. the second ip in my public subnet?
I ve setup Anyconnect on ASA 5510 and it seems to be working fine but cant get Jabber to work on smart phones. When using the packet tracer i see my packets dropped on WEBVPN-SVC. I am not using NAT anywhere and i can normally ping the CUCM from the client , i can open the web page of cucm but jabber says connection error.
I have this scenario, AS5510 ver 8.4(3), VPN Client 5.0.07, RADIUS authentication with IAS on Windows 2003 Server.The issue is that, establishing the connection with the VPN Client, if the user credentials are correct every things works fine, but if we introduce a wrong password I don't receive an error message or a again the authentication form.Nothing happens the VPN Client keep trying to "contact security gateway", after about 5 minutes it stops without any message.Debugging the authentication process in the ASA I see that if the password is incorrect the radius authentication response is "reject". I have also tried with a different version of VPN Client but nothing change.Using AnyConnect client every things works fine.
I'm using an ASA5510 with AP1130 and attempting to set up a public and a corporate WiFi-network. The corporate one should allow users to authenticate with Radius running on MS ISA for access.
VLAN70 security level 1 (IP-range 10.10.70.0/24) for open guest WiFi. VLAN71 security level 100 (IP-range 10.10.71.0/24) for corporate users WiFi. VLAN100 security level 100 (IP-range 10.10.100.0/24) server network (only wired servers).
ASA is gateway at 10.10.70.1, 10.10.71.1 and 10.10.100.1. It is also DHCP-server for VLAN70 and 71.
Radius server is at 10.10.100.5, listening on port 1645 and 1646 for EAP/PEAP and MS-CHAP v2.
I get both WiFi-networks with VLAN 70 and 71 working without encryption, ie. open networks. Traffic flows fine and get network access without problems.
The problem I run into is that it seems the Radius server must be on the same network as the WiFi-clients for them to be able to authenticate with it. That is, I tried to use VLAN100 as the corporate WiFi network and then I am able to connect, authenticate and get network access if I also enable DHCP for that range. However with VLAN70 as WiFi I am unable to authenticate with Radius on VLAN100. It seems the AP can reach the Radius server but clients never get connected and eventually fail with an error.
I can ping the Radius server from the AP. All traffic should be allowed from VLAN71 to VLAN100 in the ASA. Packet tracing shows no errors there.
The switch is a 2960G with the following interface config:
We have gotten our anyconnect clients to connect to the VPN with no issues and verifying credentials with RADIUS. Remote users however cannot access internal resources through the VPN. I know I need to setup an NAT Exempt statement for my VPN Pool to the Internal Network,
I currently have our ASA5510 setup for AnyConnect 3.0 VPN clients and IPSec VPN clients. I'm trying to add Clientless SSL VPN functionality for employees without company laptops. Because they won't be using company PC's I want them to connect to the webvpn portal without having to install any type of client.
I have a Clientless SSL VPN connection profile setup and have it set to use Clientless SSL VPN only. However, whenever I login to the portal it automatically tries to download and install the AnyConnect client. How do I enable the VPN web portal without the AnyConnect trying to install?
We have about 160 users setup using the Anyconnect client connecting to a ASA 5510. We are using split tunneling and also using the Websense endpoint client. Every now and again after installing the endpoint client we are unable to connect the AnyConnect. It asks for credentials waits for a while and then fails with the error "AnyConnect was not able to establish a connection to the specified secure gateway.Please try again later."
If we uninstall the endpoint client it works again and normally after reinstall it fails again ( I know). Eventually it just works and then its fine.
We have logged a call with websense and sent packet traces of working and none working . Then only thing they came back with is if we filtered the non working trace with port 80 you could see a few RST,ACK coming from the ASA to the client so they blamed the Cisco components.
I'm trying to install the anyconnect package on an ASA 5510 running version 9.0.1. I'm getting the following error:
labfwpix(config-webvpn)#anyconnect image disk0:/anyconnect-win-3.1.01065-k9.pkg copying 'disk0:/anyconnect-win-3.1.01065-k9.pkg' to a temporary ramfs file failed
Is there something that I'm doing wrong when installing the package?Also, is there away to manually install the client on a stand alone PC without a deploying method, similar to the IPSEC client software?
I just upgraded our AnyConnect package on our ASA5510 from 3.06xxx to 3.1. When I tried to log in to the website to automatically install the client, it showed me a big error saying the Certificate is untrusted and I have to explicitly accept it. After accepting it, I had to restart the installation.Is there a way to disable this strict certificate trust setting? We don't have a valid SSLVPN certificate yet, but this big error will confuse endusers.
I have a scenario where there is an ASA5510 configured as follows:
Interface0 = Outside Interface1 = LAN Interface2 = DMZ Interface3 = unused Running ASA version 8.2[1]
All network operations are fine, as are the IPSEC tunnels to other branch offices, and the incoming SSL VPN accessed via the IP address assigned to the external adapter.
My problem is that I have a device on the DMZ that needs to access the AnyConnect service hosted on the external adapter so that it can access LAN resources. When I try accessing it, I see the following errors appearing in the debug log:
3Dec 03 201212:10:50710003[DMZ client address]51031[AnyConnect ExternalAddress]443TCP access denied by ACL from [DMZ client address]/51031 to DMZ:[AnyConnect ExternalAddress]/443 If you look closely, it suggests an ACL issue from the DMZ client to the external AnyConnect IP address BUT it suggests the Anyconnect IP address is on the DMZ interface.
Recently upgraded a 5510 to Anyconnect Essentials and Anyconnect Mobile, the device was Security Plus and is now Base. Is it supposed to work this way? I lost my Gigabit interfaces. Is it possible to have Security Plus + Anyconnect Essentials?
I am trying to setup a VPN with AnyConnect on my ASA5510 and it works fine. I have setup an AAA server group for my Active Directory with the "NT Domain" protocol". Right now, every user is able to connect with their Active Directory credentials. I would like to restrict access to the Anyconnect VPN to only a few users in AD.
we have ASA5510 with version 7.x and asdm 5.X, i upgraded it to 8.3 and asdm 6.2, and i got vpn peers 250 and 2 ssl.when i try to connect through client software , i can see in the logs UDP 500 port is created as shown below. [code]
and currently in right panel of Active Algorithms i have only RC4-SHA1,

I have an ASA5510 that I am trying to set up for remote access using SSL VPN with the anyconnect client. I have followed the config guides on the Cisco website as well as the config guides elsewhere on the internet to no avail. When going to https://(outsdie interface ip address),I get nothing, the browser never loads a page. Here are the commands I have entered:
I have a clientless VPN configured for webmail on an ASA 5510. However for some reason it also displays in the drop down of the Anyconnect client, and consequently if you try and connect you do not get redirected to the webmail page. Does any know how i can either remove the entry from the drop down of the Anyconnect client, or force the webpage to open if connection is granted via the AnyConnect client?
I've got my AnyConnect setup to get an IP from our Windows DHCP server just fine. It grabs the IP, mask, and DNS just fine. But I can't ping any of the lan devices or do any DNS lookups. I need it to work this way since we have a ton of site-to-site's with remote offices and getting them all to adjust their firewalls to allow another subnet is a nightmare.
I have split-tunneling enabled. I'm sure it's a nonat command that I'm missing, but not sure what.
Before connecting to VPN: Home user-------------------> ASA 5510 --------------> Office Lan 192.168.1.0/24 10.10.1.1/24
After they connect to AnyConnect Home user-------------------> ASA 5510 --------------> Office Lan 192.168.1.0/24 10.10.1.1/24 10.10.1.45/24
I currently have a HA pair of ASA5510's, as I understand it the 2 free premium licenses can be used by the mobile client as long as the ASA has the license for the mobile clients?
Can any one confirm that my understanding is correct, or would i need to buy a seperate Premium license a long with the mobile client license to enable this functionality?
I have a Cisco ASA5510 firewall that has SSL Web VPN functionality and is utilizing AD Server as Authentication server for users.However, we have a policy to change password at certain point of time. Users in the office have no problem. They just login their PC and change password. Users outside of office is a pain when their password is expired. Is it posible for them to change their AD password thru VPN using Cisco Anyconnect?
