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.
my question is "do I need a statement for http on the access-list ?"
thank you.
here is the config
PIX-525# wr t
PIX Version 6.3(1)
access-list 100 permit tcp any host 155.1.1.4 eq http
access-list 100 permit tcp any host 155.1.1.4 eq smtp
access-list 150 permit tcp any host 155.1.1.4 eq http
access-list 150 permit tcp any host 155.1.1.4 eq smtp
access-group 100 in interface outside
static (inside,outside) 155.1.1.4 192.168.1.4 netmask 255.255.255.255 0 0
aaa-server AUTHEN protocol tacacs
aaa authentication match 150 outside AUTHEN

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.

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.

ASA cut through proxy with RADIUS challenge response?

Have this working for IPSEC VPN on same box (tested on 8.2.1 and 8.2.3)
Want to do cut through proxy with challenge response - same ASA and same RADUIS server but using aaa authentication match command and this is what happens...
It looks like the ASA sends a completely different radius authentication request than with VPN authentication request. Is there any way to specify what request is sent?

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 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 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:

i get the auth-proxy login page when the host on 10.1.1.3 is trying to access 20.1.1.2 web site .
after putting the login credentials i get authentication failed
i tried the debug. i see the router is sending the authentication login and password and getting the status from the acs as pass. i also see the auth-proxy triggered. in there i see
AUTH-PROXY PROTOCOL NOT CONFIGURED.
could someone pls help me what could be the problem. i am have tried many times to get this work. but not fortunate enough.
am i missing on any commands on the router or on the acs. i tried doing as the example mentioned in the student guide but still failed. pls help. waiting for some reply.

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

Please refer to below step by step config guide for security group access policies

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:
http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/aaa.html#wp1069492

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

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.
4          Aug 21 2012          06:04:26 222.222.222.146          50414 111.111.111.162          3391          Deny tcp src outside:222.222.222.146/50414 dst inside:111.111.111.162/3391 by access-group "outside_access_in" [0x0, 0x0]
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

Adding Pix device public interface through Proxy server into CSM Fails

Hi
I am trying to add a device into CSM. The device is only reachable through proxy server. If i try to add the device, the connectivity test fails" unable to communicate with device". If i debug on the PIX i see no connection attemps. If imake a https connection from the Explorer from the windows server running CSM i get connected. I have set the proxy settings under Server Administration. I can update packages from CCO through the proxy. Is there somewhere else to tell CSM to run through proxy ?

Hello,
maybe your problem has to do something with loading SLPDA.NLM. If you
cannot get to open Autoexec.ncf then go back to DOS-Mode, rename this
file in C:\nwserver-directory and start again. i have seenthis behaviour
on servers loading SLPDA with no network-communication and they stop
loading at WPSD.NLM. Try to load SLPD.NLM manually when the server is
up. After that shift the line in Autoexec.ncf where you want to load
Slpda.NLM to the end of the file and boot the server again to see what
happens.
Good luck

Can't access some secure sites through proxy?

can't access some secure sites through proxy server on osx it just keeps going local authority couldn't be contacted, i had the same problem with parental controls, but now that is off and its still doing it, is there a setting or something i need to enable?

In my original post, not today's, I had said I was having the issues on the Mini, running OSX 10.6.8 and Safari v.5.1.5 for my bank's pill pay. I should have been more specific as to which machine and OSX Safari browser I'm having the T-Mobile problem with. My mistake.
It is on both the MacMini and now the Air too. A moment ago, I was able to log in to my.t-mobile.com on the Air, but after putting into my Bookmarks folder, I can't do it anymore. The Log in button comes up greyed out instead of green.
I'm also still having trouble with my bank's bill pay section on both computers too.
I wonder if it's related to the saving of the log in info or putting in the Bookmark Folder?

Help: Problem with scrolling my html items and placed objects they keep cutting through my top menu

Basically whenever i place an html item in my Muse site or an object I encounter a problem when scrolling down past that object in the preview. I have a horizontal menu bar that sits on the top of my site and whenever I scroll down the html items and objects
cut through my menu. Is there any way to rectify this? - i've tried pinning objects but can't figure it out. Any help would be greatly appreciated.
Thanks,

So you have a pinned Menu in the Master page but is being overlayed by the objects in page when you scroll down? If that is the case, select the Menu in the Master, right click on it and Move To Master Foreground.
Thanks,
Vinayak
