ASA Cut through proxy configuration

Hi guys,
I would like to configure limited internet access to olnly a select group of Windows AD users.
I beleive cut-through proxy will allow me to do this, just not sure how to configure it on a Cisco ASA-5510
thanks

The link given will definitely work however you would not be able to select access based on the AD group, if that is what you need to achieve and you have ASA version 8.0 you can work Cut-Through-Proxy together with DAP.
Using Cut-Trough-Proxy with a standard authentication server will only allow or reject depending on the authentication result, but any user within your AD schema will be able to get internet access. If you need to restrict this based o Windows Groups as well your best shot is Cut-Through-Proxy with DAP and LDAP:

ASA - cut through proxy authentication for RDP?

I know how to set this up on a router (dynamic access-list - lock and key)... But, I'm having trouble understanding how to setup OUTSIDE to INSIDE cut through proxy authentication for RDP.
OUTSIDE to INSIDE RDP is currently working.
I have 2 servers I want RDP open for..
[*]OUTSIDE 1.1.1.1 to INSIDE 10.10.70.100
[*]OUTSIDE 1.1.1.2 to INSIDE 10.10.50.200
What's required for OUTSIDE users to authenticate on the ASA before allowing port 3389 opens? I was hoping for is a way to SSH into this ASA, login with a special user, then have the ASA add a dynamic ACE on the OUTSISE interface to open 3389 for a designated time limit. Is this possible?
Here is my current config.

You're running ASA 8.2(5). In 8.4(2) Cisco added support for what they call Identity Firewall rules. That is, you can make access-lists entries specific to users (or object groups containing users).
There's an overview document on this posted here. It's a bit dated but I believe the only change is that Cisco is now preferring use of the more current Context Directory Agent (CDA) - a free VM they provide - vs. the deprecated AD agent (software service that runs on your DC).

ASA - Cut-through proxy probleme

I have to configure my ASA 7.2.2 for cut-through proxy but when the users use authentication prompt ,
but only , for (http://1.1.0.2/netaccess/connstatus.html) the ASA send the following message:
User Authentication
User Authentication is not required.
help me
it is ok when one uses cut-through-proxy by ACL :
access-list ACL_INT extended permit tcp object-group PC-UAUTH_DYN host MVINCT19 eq www
access-list ACL_AUTH line 1 extended permit tcp host poste_auvinet host MVINCT19 eq www
aaa-server auth_inside protocol radius
aaa-server auth_inside host SVR-ACS-IN
key xxx
username admin password xxx privilege 15
aaa authentication match ACL_AUTH inside auth_inside
aaa authentication listener http inside port www
on a pix 525 is OK

Hi,
The config looks good. Please remember that successful authentication is cached (show uauth) and till it expires user will not need to authenticate again.
Please clear uauth and see if it helps.

Vivek

ASA cut through proxy with RADIUS challenge response?

Thanks in advance

Hi Ian,
sorry for the late reaction - do you still need help with this?
The difference between the working (VPN) auth and the failing (CTP) auth seems to be that VPN is using PAP (so no challenge-response!) while the CTP is using MS-Chapv2
So my guess is that your Radius server does not support MS-Chapv2. If that is the case then you may want to try this:
aaa-server () host
no mschapv2-capable
Although this command is not really meant to be used in this scenario, so I'm not sure if it will work but I'm hoping it will make the ASA revert to PAP for all auth requests to this host.
Note that you won't be doing challenge/response, so your passwords will be transmitted over the wire (encrypted).

ASA Cut Through (Authentication) Proxy for a Single ACL

I have a customer that wants to authenticate users at the ASA before being allowed access from the outside into a payroll server on the DMZ. I am aware of the cut through proxy feature, but doesn't that affect all traffic entering the DMZ? Is there a way to only authenticate users accessing one server?

Hi,
Seems to me the easiest way to do this is you are connecting to the destination server with either Browser or CLI based connection.
For example if its a browser based connection then you could configure
username password privilege
access-list PROXY-AUTH extended permit tcp any host eq http
access-list PROXY-AUTH extended permit tcp any host eq https
access-list PROXY-AUTH extended deny ip any any
aaa authentication match PROXY-AUTH LAN LOCAL
I don't think you even need the "deny" statement since there is an implicit deny at the end of each ACL
Where "LAN" is my interface "nameif" connect to my LAN network.
To my understanding if you are using some application for this connection that doesnt apply in this situation then you would have to configure this in another way and the user would have to first connect manually to the ASA for authentication and would then be allowed to connect to the resource.
Have a look at this document for some help

Pix cut-through proxy

a quick question since I do not have access to a pix I can not confirm it
say, I want to do pix cut-through proxy and authenticate access via tacacs on per user basis.
I want the user to access smtp user inside the pix will go through tacacs authentication.

Cut-through proxy is a feature unique to PIX Firewall that allows user-based authentication of inbound or outbound connections. A proxy server analyzes every packet at layer seven of the OSI model, which is a time- and processing-intensive function. By contrast, the PIX Firewall uses cut-through proxy to authenticate a connection and then allow traffic to flow quickly and directly.

Cut-Through Proxy / Authentication Proxy on Cisco ASA using ISE as AAA Server for allocating SGTs

Hi,
We are trying to setup ASA to do cut-through authentication proxy, and use ISE as RADIUS. We can successfully authenticate the user from Radius on the ASA, while he opens a web-page, but then it displays the error: authorization denied.
What we want:
ISE to allocate a security group tag to the user session when he logs in, that tag would carried within out cisco network infrastrucutre to define the access
policy for that user.
Can someone please help me with a sort of step by step thing for ISE configuration to allocate SGTs/SGACL for the user session after authentication is completed.
Thanks
Lovleen

Does Juniper have anything similar to Cisco's 'cut-thru proxy?

Has anyone configured a Juniper to authorize users 'thru' a firewall?
Sent from Cisco Technical Support iPad App

Hi Bro
You're lucky I'm in a good mood today. Normally, I won't answer questions pertaining to non Cisco products, because I have less faith in them but I guess I'll answer your question.
Yes, Juniper Netscreen FW do have similar feature with Cisco Cut-Through Proxy. It's called WebAuth. For further details on this, please click on this URL http://kb.juniper.net/InfoCenter/index?page=content&id=KB4103
Here are some extra info for you :-)
a) Only FTP/Telnet/HTTP are supported if you want to have transparent interception.
OR
b) If you want to let all users to be authenticated first then the option is WebAuth in which user has to manually type in the WebAuth Server IP Address configured at NetScreen to authenticate themselves before they are granted access to any services
c) Only Local Database, RADIUS and LDAP authentication source are supported (No TACACS support as opposed to PIX/ASA)
P/S: if you think this comment is useful, please mark this question as answers and rate this comment nicely :-)

Cut-through/direct authentication connection being denied

I'm trying to set up a firewall so an outside user can authenticate to the firewall, then RDP directly to a workstation.
Here's what I've got:
aaa authentication match authmatch outside LOCAL
aaa authentication listener http outside port 5555
access-list authmatch extended permit tcp any host 111.111.111.162 eq 3391

static (inside,outside) tcp interface 3391 192.168.1.101 3389 netmask 255.255.255.255
I can connect to the web page and authenticate successfully.

But, when I try to RDP in on 3391, it's not hitting the authmatch access list.   It's hitting the outside_access_in access list and it's denied by the default deny.

Why won't it hit the correct access-list?
Thanks,

Hello Marc,
What Karthik is telling you is the following:
-The cut through proxy adds additional control regarding the connections across your firewall, this by using the ASA as a proxy but you still need to allow the traffic on the proper ACL's on the interfaces of your ASA.
So just create an ACL entry into the outside acl permiting traffic to port 3391, of course only the users authenticated will succesfully connect

Web-Proxy(cut-through) without ACS on 55xx

Is it possible? All I have read about it requires an external server.

I think that is a limitation of IOS Auth-Proxy and not ASA/PIX Cut-Through.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fsecur_c/ftrafwl/scfauthp.htm#wp1001164
However AFAIK you can only authenticate using local password database and not authorize using it (for CUT-THRUOGH). Have a look at this table:

Cut-through authentication vs. virtual telnet/http

Hi,
I'm having difficulties understanding the meaning of the virtual telnet/http commands on the ASA.
I have configured an ASA and defined an access-list with all the traffic which is to be authenticated. These are protocols like RDP, which can't be intercepted by the ASA, but also HTTP and HTTPS which can indeed be intercepted (this is also referred as cut-trough authentication).
The setup principially works. Then a few consultants came and checked my config for errors. They also performed a portscan, where they found out that all protected services (which should only work after authenticating) were answered by the ASA (a tcp-session was started), so an attacker would know what potential services are behind the firewall.
The customer (and me) disliked this behaviour, and I thought this could be solved by using the virtual http feature. Define a seperate IP-Adress, to which you can connect via HTTPs and authenticate, after which you can reach all other services.
Can this be done with this feature? My testresults showed just the behaviour, that you can authenticate at the virtual http-address, but the cut-through authentication is still active, so that's not the solution.
To be honest, I even believe that the virtual telnet/http feature is completely useless! Why? Because to make it work, you have to
1) allow the ip an the inbound ACL
2) add the ip in the ACL where the authenticated traffic is defined
3) configure a NAT for this ip to be routed inside
I don't really see a practical reason for this command - Thanks for your thought...
Florian

Hi Florian / Jeff
I agree largely with what you are saying and have found similiar issues with it. if you are already authenticating to a web service the additional config of a virtual http service seems unnecessary.
But i think one instance where virtual telnet is useful is if you have services such as RDP etc. that you need to authenticate but you don't have a web server or telnet server to authenticate against.
Without virtual telnet i'm not sure how you could setup access to these services so you would need virtual telnet in this case.
Where i find the command particularly useless is that i want to authenticate people accessing for example terminal servers on a particular subnet. This subnet is also running web servers.
Now say i want to do this via http authentication. I'm trying to authentciate them because i don't know their IP addresses. So i enter an authentication command for http but now everyone who wants to use http has to authenticate and not just people who are going to be using terminal services.

ADFS 3.0 - Web Application Proxy configuration Issue

Hi All,
We are in the process of implementing ADFS 3.0 published to the internet for o365 Federation purposes.
The setup consists of the following
- 2 x windows 2012 R2 running ADFS 3.0 ( only one server presently installed and configured though)
- 2 x Windows 2012 R2 Running Web Application Proxy ( only one server presently installed and configured though ).
There is an F5 Big-IP load-balancer for both internal and external interfaces and it has been configured after a lot of issues with the SNI part on the F5.
So, in short the setup is now a single server hosting ADFS 3.0 using SQL and a single WAP server, however the traffic to these servers are still going through the LB.
Now the issue is that i cannot complete the installation/configuration of the Web Application Proxy server. There is a firewall in between our DMZ and the internal network. I can reach the internal services via the following url and telnet on port 443
to the federation service as well. (ports for 443 and 80) are opened to internal network on the load balancer ip . I can reach https://fs.domain.com/adfs/ls/idpinitiatedsignon.aspx and federationmetadata/2007-06/federationmetadata.xml location as well
from the Web APplication proxy server without any issues or certificate prompts at all.
When i do the configuration for WAP, i use the same account which was used as a service account for the ADFS service internally. If i use a local admin account, it errors out with another message stating the connection was closed.
The certificate on the internal server along with its private key was exported and has been imported on the WAP server . This is not internal CA, instead we are using DIGICERT SSL with SAN Names for enterprise registration and work folders. Hence the CA Chain
issue is ruled out and also this is not a wild card certificate.
When the wizard starts configuring, it does establish the trust with the federation service which is shown up in the event viewer with EventID 391 within 15 seconds i get another event id 422 which states that it cannot retrieve the proxy configuration
and eventid 276 on the Federation server which states the authentication failure. this continues until the servers stops to try configuring the wizard.
I have read all the available threads on the 3.0 WAP installation /configuraiton problem and tried all the steps possible but i am still stuck with this issue.
There is one more part that i noticed on the ADFS server, that the self signed services for the token-encrypting and token decrypting are self-signed certificates. Also, in the certificates it was showing up as not trusted. and i installed them to the TRUSTED
ROOT CERTIFICATION STORE after wich i cannot see any private key showing up when viewing the certificate which means i cannot get the MANAGE PRIVATE keys option when right clicking on the cert to assign read permissions for the ADFS service account.
Should i assign the same SSL sertificate (SAN based for enterpriseregistration & Workfolders) to the token-encrypting and token-decrypting services in ADFS console or should i leave them as self signed ? I did read that self-signed is not recommended for
production environment ? If not the same certificate what are the requirements for the certificate ?
I am not sure what I am missing in the configuration that is causing this issue. The WAP servers are not part of the domain and have also ensured the time synchronization between the domain machine as well.
The service name is fs.domain.com on both the internal and external DNS ( we have domain.com as a zone in DNS internally as well ). I am able to Authenticate inside and from the WAP server when accessing the link.
Could it be a Load Balancer Configuration ? [i will try eliminating this from the configuration]
Let me know if there are any options that i can try to resolve this and get the configuration working.
Cheers,

Does the load balancer pass the certificate session through to the ADFS server or are you offloading SSL. SSL offload does not work with WAP/ADFS integration (at least at the time of writing it does not).
Can you try through the load balancer with SSL pass through turned off please.
Also as ADFS 3.0 (Server 2012 R2) uses Server Name Indication (SNI) then any health checks that run on the load balancer must support this, so if they do not then you need to use TCP 443 checks for a listening port, as doing a standard HTTPS check will fail,
and if the load balancer fails its checks whilst you are configuring ADFS that might be a reason why it has gone offline for you (error 442 is to do with failure to swap client certificates between WAP and ADFS).
Finally, check the June update to Server 2012 R2 (http://support.microsoft.com/kb/2964735) as that has fixed some certificate issues with multiple servers for WAP and ADFS when you don't have the
2012 R2 AD schema in place.

Getting through proxy servers

Hello,
Does anyone know if the URLRequest / Loader classes are able
to connect through proxy servers? In other words, does Flash read
the PC's proxy configuration and automatically use it?
Also, I was wondering, if one was to create a Socket and then
connect to a web site...
mySocket.connect("www.mydoman.com", 80);
but the user's PC uses a proxy server to connect to the
Internet, would this
connection succeed or fail?
Thanks for your insight.
Dan
