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
We have a pair of ACS 4.1 servers (Windows Server 2003 R2). Let's call them ACS1 and ACS2. We don't want either one of them to proxy to any AAA server, including each other. We're using mostly TACACS authentication.
While troubleshooting a general problem, I'm guessing that one of us did this on ACS1:
pressed the Network Configuration button,saw the Proxy Distribution Tableclicked (Default)moved ACS1 from the AAA Servers column to the Forward To column.
So, essentially, we're telling ACS1 to proxy all requests to itself, which doesn't seem to make sense. I don't know for sure whether it should work when configured to "self proxy," but in that state, it does not authenticate anyone and gives merely "Internal error" as the reason.
If I change the configuration so that "ACS2" appears in the Forward To column, and I move "ACS1" back to AAA Servers and restart, ACS1 starts responding correctly to TACACS requests. Of course, ACS1 is just proxying all requests to ACS2, so having two servers isn't doing much good.
I cannot simply remove ACS1 from the Forward To column and leave it empty. The interface complains that it can't forward to zero servers. Of course, on ACS2, there are no servers in the Forward To column, since we never touched the Proxy Distribution Table there.
Is there any way to return the Proxy Distribution Table to its default setup, that is, no servers appear in the "Forward To" column?
We're planning to upgrade to version 4.2 very soon, so this question is mostly academic, unless the same problem exists in 4.2.
For full disclosure, I should mention that the problem we were troubleshooting was loss of connectivity to our Windows Domain Controllers from our ACS servers. We had missed adding some exceptions in our firewalls to allow for four new DCs. As far as we can tell from testing, connectivity to the DCs is now fine. The firewall rules group ACS1 and ACS2 together, so connectivity should be the same, and ACS2 authenticates users correctly.
I am try to configure ASA 5510 with 8.3 IOS version.My internal users are 192.168.2.0/24 and i configured dynamic PAT and are all internet .
i want configure identity NAT for remote access VPN.Remote users IP pool is 10.10.10.0 to 10.10.10.10
i know to configure NAT exemption in IOS 7.2 version. But here IOS 8.3 version. configure NAT exemption for 192.168.2.0/24 to my remote pool( 10.10.10.0 to 10.10.10.10).
I'm planning to migrate a customer from ACS 4.2 to ACS 5.3.
I have migrated the configuration for all the services but I'm thinking how to configure ASA 8.4 cut-through proxy service in TACACS+.
The same ASA uses TACACS+ for device mngt and RADIUS for vpn remote-access services.
We have a custom web application which is heavily relying on javascript. We're trying to access it via the webportal but this application does not load correctly (it barely shows a white page).
the link is [URL] and SUBIF-ISP2 is the public interface facing the internet. This is the rule as displayed by the CLI:
proxy-bypass interface SUBIF-ISP2 path-mask oursubdirectory target [URL]
Despite having this command in place, nothing changes. I tried multiple combinations adding the xml and hostname rewrite or changing the interface but nothing, the page is the same like if this rule was not applied.
We are running with Cisco ACS v4.0 AAA server, Here I need the use of Proxy distribution table.

Is there a way to take them to the original page they requested after the login is complete, rather than having it sit at the screen where it is says they are logged in?
View 1 Replies View Relatedi would like to use the ACS 5.3 as TACACS Proxy. Basically it works. But when checking the logs on the destination TACACS Server (ACS 4.2) i see that all requests (Source-NAs) came from the IP of the TACACS-Proxy. Not from the original source IP.
This is useless for my scenario, because on the destination TACACS Server the policies are built on the NetworkDevices Groups and AAA Clients = source IPs.
Can i configure proxy on ASA 5510? i.e for internet use my user should be authenticate by ASA5510 and after successful authentication user should be allowed to access internet and futher is it possible to do bandwidth managment with ASA5510?

I can only use the internet browser. If I try to change the proxy, to enter the blocked websites.Is there a possibility to unblock the websites without changing the proxy configuration?

View 1 Replies View RelatedWe are currently using Cisco ACS 5.3.0.40.2. One of the Services Selection Policy it hosts is:
Receive Authentication request from a wireless controller for a wireless userIf the wireless user's username contains a particular domain suffix, the request is proxied to an external proxy server using an External Proxy service (configured for both local/remote accounting)On receiving an Acccess-Accept from the external proxy, the user is given access and ACS 5 will start logging account packets for the username (nothing appears in the RADIUS authentication logs - ACS 5 it seems doesn't log proxied authentication requests) The above setup works fine in most instances. We start to have problems when an external proxy server strips the domain suffix off the username in the Access-Accept packet e.g.
ACS 5 proxies an Access-Request to an external proxy server (with Username = someuser@somwhere.com)The external proxy replies with an Access-Accept (with Username = someuser)The user 'someuser' is given access but subsequent accounting attempts fail because their username (without the domain suffix) doesn't match the Service Selection PolicyIs there any way to get ACS 5.3 to log proxied authentication requests? If not, can I configure ACS 5.3 to use the username in the Access-Request packet (rather than the username in the Access-Accept packet) for accounting?
I am working on a task of redirecting any unmatched http traffic to Symantec public transparent proxy through Cisco ASA. For the definition of uncatched http traffic, we have inbound squid servers for deploying IE proxy pac and redirect the http traffic to Symantec public transpraent proxy, however we can't deploy IE proxy pac to mobile device and non-support web browers.Since we have some application using IE proxy setting for direct http communication with external domains, the current symantec policy addes those domains in the exception list so that they are not redirect to Symantec public transparent proxy server.
-For the platform - Cisco ASA 5510 ASA 8.4(4)1
-For the solution, I have the following two nat rules
I would like to connect devices to my network so that their traffic passes through a proxy running on my computer. I figured the best way to do this is by setting the proxy on my router to the one I am running, but then I would need to have another connection to the computer running the proxy or else there would be an infinite loop ?? something like that. so:
Internet -> router (1) -> my proxy on comp A -> router (2) -> computer B
I access the internet from my company�s LAN, which has a restrictive firewall, so I cannot request the admin to open any ports manually for me. Hence I use a software called your-freedom. This proxy software supports both http as well as socks 4 and 5 proxy (by entering the proxy IP 127.0.0.1 (localhost) and Port 8080 for http proxy OR 1080 for Socks Proxy), and I have successfully been using web browsers and some other softwares that support proxy/ allow proxy info to be entered to login/ connect to the internet. Your-Freedom also supports port forwarding.However, the softwares I intend to use do not have any options to enter proxy methods or proxy ports (as far as I have noticed). I have tried to proxify these 2 softwares using softwares such as SocksCap and Free Cap, but either they don�t work, or my settings in proxifying are not correct. I believe I will have to do port forwarding or proxify the softwares, but have been unable to do so in the correct manner.
Following is the info on the 2 softwares:
1.NOW Trading terminal:[FONT=Times New Roman]Normally when I start the NOW or Zerodha software, the software starts and I get a login screen, but under firewall conditions, I get the initial Splash screen but then the software stops with the error: [b][u]NOW Initialisation failed for Interactive Engine << os error>>.
2.PowerIndia Bulls:The software is written in Java and starts with a batch file (PowerIndiabulls.bat) located in C:UsersDEFAULT_USERNAMEAppD..... I converted this batch file to .exe (with battoexe software) and then ran it through a proxifying software. The .exe start properly without proxifying software but not under proxifying environment. Basically the software needs to connect to the internet using Port 443. I am also expected to keep ports 443, 41599 and 59598 open. software's requirement is available at Indiabulls Securities: Indiabulls Securities is a leading capital market company offering securities broking and advisory services, depository services, equity research services to its clients in India. (item no. 5).To confirm, while the software is unable to connect through port 443, you will get an error message: "Connection to Login Server could not be established" when you try to login with any random Username and Password.To know that the software is able to connect properly, you will get an error: "This User ID is not enabled to be used with this product".
Anyone know the differnce between these two on a MLS? Seems that proxy arp as I know it works with or without the 'local' version.

I have a Cisco ASA 5510 connected to 2 private lans (1 for my HQ pc's{inside} and 1 for the worldwide mpls{outside}) It is also connected to the public internet at interface "public" and my dmz at "dmz" interface. I suspect I have a routing issue because packet-trace yields allow, the nat looks ok and the objects look ok at least to me but I'm the one with the non working config so...Basically this is the desired flow:
1. I need all traffic from the inside to be able to flow to the outside unimpeded as they are both trusted networks. (this is ok right now as I allow everything via access-list 101.)
2. I need any host on the public internet to be able to reach a server on the dmz via the pat which I set up from the "public" interface to the "DMZ" interface. The desired flow would be that the person on the internet types in [URL] and this is directed to the public interface ip which forwards to the webserver object on the dmz. (I cannot get this working any which way)
3. I need the dmz to be able to communicate with another server on the mpls via the "outside" interface when it recieves the request from the public it then checks with this other server on the outside via nat(translating the dmz range into the ip of the outside interface on the firewall)I have a default route that points to the mpls or outside interface for 0.0.0.0 0.0.0.0 via 10.x.x.1 - (and although I'm not sure I suspect this could be conflicting with traffic that needs to be sent to the "public" interface .... meaning that the firewall should dump packets bound for 0.0.0.0 0.0.0.0 to the public interface - 184.x.x.194 but I'm very reluctant to change the default route as this is in production and I'm not sure how it will affect traffic).However, I do suspect that if I changed the route from default to static as such:
route 10.0.0.0 255.0.0.0 10.x.x.1 (this would get all lan and mpls traffic to the mpls gateway) route 0.0.0.0 0.0.0.0 184.x.x.193 (this would send everything else from public to the public internet gateway)I think this is accurate but then I would bypassing my corporate internet proxy which is behind the mpls gateway at 10.x.x.1? Is there a way to get http traffic originating from the lan (10.x.x.x) to use the mpls gateway and http traffic for the dmz to use the public internet gateway at 184.x.x.193. I don't want to start causing a flow problem for the internet nor do I want to bypass my corp internet proxy.Either way I cannot get this to work, eventhough the logic checks out, I cannot get even a ping response when I allow icmp any any for testing. Note: I can ping resources on each network from the firewall, not only it's own ports in the associated network but other resources on those networks as well.

we have a cisco ASA5510 and our client owns a Juniper device. we already have a vpn tunnel in place between the two locations and its working fine.Now, they have some networks which are in more secure zone, if we add those subnets to the present tunnel we are not able to access them. so what they are suggesting that we can reconfigure the VPN to be a route based VPN instead of policy based OR configure a second VPN tunnel.am not sure of cisco ASA supports route based tunnels???.. Can we create a 2nd tunnel between the same devices ( asa5510 and thei juniper device) as the IP remains same, only the internal remote networks will change for me. do i need to make any changes to the present tunnel??
