Transparent proxy with ACE+CE (Client-ip spoof) slow response.

I have configed transparent proxy with ACE and CE510+Bluecoat. I also enable client-ip spoofing. I use PBR for redirect request web page from client to ACE and I also use PBR for return traffic from any web servers to ACE(make complete flow for client-ip spoofing). Any thing is fine, but I have a little bit issue that when I try to browse to the new website and ACE load my request to CE510, I seem long time for page response, I monitor at ACE, it show connection is "ESTABLISH". When first page on these new website response after that I try to browse other pages on these new website, the response is normal. This happen for everytime that I test. I have already send configuration of ACE and CE. Anyone, please see anything that I config is correct. Thank you very much.

System-wide Transparent Proxy With URL Patterns

Internet censorship -where I live- has almost turned web unusable so I decided to setup a transparent proxy using Tor for my home network.
Since Tor is so slow -here- proxying all traffic through Tor would slow my connection to a crawl. Therefore I need a mechanism to selectively proxy the traffic.
I know a bit of 'iptables' and it looks to me like the solution to my problem. However there's a trick. As most of the websites I need to access through Tor (like Google+, Facebook and such) use several IP addresses for their entry points, it's almost impossible for me to add 'iptables' rules for all of those IP addresses. I need a mechanism to proxy the traffic based on URL patterns. For example I need to be able to proxy access to '*.facebook.com' through Tor.
So the question boils down to: how can I setup a system-wide transparent proxy using URL patterns?
Any idea/hint is much appreciated. TIA,
Bahman

Config transparent Proxy with LDAP authen with L4 switch?

How to config policy based routing on L4 switch if wsa run in transparent mode with LDAP authentication?
Async OS: 5.1.0-420
Thank you,
Thanapol

Ezekiel,
I wanted to add some clarification to your comments:
1) Network TAP connected to T1/T2.
This will work good. You will need to tap one direction of traffic to the T1 port and the other direction in to the T2 interface.
2) L4 switch connected to P1.
This will NOT work. Further explaination below. What you can do is use a switch that supports port spanning / port mirroring. You'll need to send a COPY of all traffic going to gateway to the T1 interface.
The L4TM will need to be in 'duplex' mode - Configurable in the GUI.
3) WCCP v2 connected to P1.
WCCP cannot be used at all with the L4TM, because WCCP doesn't 'copy' the traffic, it redirects it.
L4TM information
The L4TM can be thought of as a completely seperate appliance that operates primarily via the t1 / t2 interfaces.
The L4TM is a sniffer application, meaning that you cannot redirect traffic to it (such as L4 switching PBR or WCCP), but you can send a copy of traffic to it (port mirroring or physical tap).
If you are blocking with the L4TM, the WSA will use M1/P1 to send the TCP RST packets. This is the ONLY use for the M1/P1 interfaces that the L4TM will use.
The P1 interface is intended to be used for Web proxy traffic and the L4TM does not listen on this interface.

ACE 4710 transparent LB with two Caches and two routers.

Hello,
I have ACE 4710 that load balance two cach flows (bluecoat), i am doing pbr on the routers to send the traffic destined to port 80 to ACE then Cach farm. After that the Cach flow will get the page from the internet via two routers. The return traffic will match another pbr on the routers with source port 80 that will send it to the ACE then CachFlow again .....then to the users.
I am not using ip-spoofing on the CachFlow for now. In the figure attached i created a VIP 0.0.0.0 0.0.0.0 port 80 on the interface on the ACE facing the routers, but the question is do i have to create another VIP 0.0.0.0 0.0.0.0 port 80 on the interface on ACE facing the Cach Flow? or just forward the traffic on the default route? What might be the default route since i have to use two routers and i cannot use hsrp?
Kindly I need some assistance
Thank you and regards,
George

Hi George,
In the topology you described, only the service-policy in the interface towards the routers is necessary. For the traffic from the caches, the ACE will just forward to the default gateway.
The only problem is, as you mentioned, that you cannot use HSRP. In that case, you can still configure two default gateways, but there is no way to predict which one the ACE will use at a given time (the way it does to select the one it will use is sending an ARP request to both gateways and using the one that replies first until the ARP entry expires)
If you need to load-balance the traffic between both routers, then yes, you would need to configure a new VIP on the cache side and load-balanced to a transparent serverfarm composed of both routers.

Daniel

IPhoto '08 Book upload errors with squid transparent proxy - tip

Hi folks
I've just "solved" a problem I was having with iPhoto Book uploads. The solution may apply to other publishing products from iPhoto and possibly iDisk uploads too.
My firewall & proxy setup is basically Linux iptables redirecting all outbound http (port 80) connections to a dansguardian filter, which in turn is passed onto a squid instance running as a transparent proxy (oh, and there's a privoxy in this all too!). Yeah, OK, I know, slightly paranoid, but I don't want my children accidently browsing stuff I don't think they are old enough for yet!
Now I had the problem before with iPhoto '06 as well, but at the time just didn't have the time or inclination to figure out what the problem was, and just did the book order and upload from the office, where it went through without a problem. This time I decided to dig a bit and see what was happening. The clue that triggered off the solution was watching the part of the order process where the book data is uploaded. In my default setup, the upload bar would scream through to 100%, and then sit there for ages, before coming back with a connection error. Watching the network flashy lights on the NIC on the firewall though, it suddenly dawned on me that what was happening was that the upload was screaming through to the squid (as there was no outbound network activity from the firewall while this was happening) and then sitting there waiting for squid to pass it on to the Apple site (as shown by the outbound NIC activity light suddenly going bonkers once the uoload bar hit 100%).
So clearly there's a problem sending book orders via a squid proxy setup as a transparent proxy. It might also very well be dansguardian interfering and wanting to take the entire upload and checking it before passing it on to squid. I already have site exception setup for all apple.com urls though in dansguardian, so didn't think it would be that. I thought about dicking around with the squid acl's but didn't have the enthusiasm to spend half the day getting that working.
So what I did in the end was tail the squid logs to see what was being proxied whilst the book order was going on, and then dropped in 3 new rules in my iptables setup just before the redirect rule. Tried ordering the book again, and voila!
The three rules I inserted were:
$IPTABLES -t nat -A PREROUTING -s ! 10.1.1.1 -p tcp -d mercury.apple.com -j ACCEPT
$IPTABLES -t nat -A PREROUTING -s ! 10.1.1.1 -p tcp -d configuration.apple.com -j ACCEPT
$IPTABLES -t nat -A PREROUTING -s ! 10.1.1.1 -p tcp -d publish.mac.com -j ACCEPT
The "-s ! 10.1.1.1" bit is obviously particular to my setup, as I wouldn't want connections from the router itself being proxied, so that may need to either be customised or left out altogether. These three rules are then immediately followed by the redirect:
$IPTABLES -t nat -A PREROUTING -s ! 10.1.1.1 -p tcp --dport 80 -j REDIRECT --to-port 8081
Hope that is of some help to someone out there!

Java client for OSB proxy with JMS Transport

Hi,
I am trying to call OSB proxy with JMS Transport. I am generating the client through ant task clientgen and following this article
http://www.oracle.com/technetwork/articles/murphy-soa-jms-092653.html
The osb proxy is req-response and is simply routing to BS which return a string value.
When I run my client, it get stuck and does not return at all. Has any one trying java client in such scenario?
What I may be missing?
Below is snipped of client code:
String url = "http://localhost:7021/sbresource?PROXY/MySample/MyJMSProxyService";
CreditLoanApprovalServiceSoapBindingQSService service = new CreditLoanApprovalServiceSoapBindingQSService_Impl(url);
MyPortType port = service.getCreditLoanApprovalServiceSoapBindingQSPort();
LoanStruct in = new LoanStruct(); //populated the data structure
String loanResult = port.processLoanApp(in); // Stuck here without any error
System.out.println("LoanResult--> " + loanResult);
Thx
/Ashwani

http://localhost:7021/sbresource?PROXY/MySample/MyJMSProxyService is the WSDL URL of the proxy.
Transport is is picked by the client from wsdl.
As far as the documentation of client generation is there, there is no change.
But meanwhile I have started working on sending the message directly to queue. JMSProxy is getting called. May be I will first run the proxy this way and then try troubleshooting the java client.

Ashwani

ABAP client proxy With Receiver JDBC Adapter

Hello Experts,
I am working on a scenerio ABAP client proxy With Receiver JDBC Adapter.
The client proxy program will fetch the master data related to equipment in plant maintenance module and will update the sql database through Receiver JDBC Adapter .
my requirement is if the equipement is created in sap then the scheduled job has to trigger the client proxy program and send the message with status 'created' to sql data base.
if the equipment is modified in sap then the scheduled job has to trigger the client proxy program and send the message with status 'modify' to sql data base.
please let me know how can i write the logic/code for this scenerio in client proxy program.
Tables for equipment master i am using is EQUI and fields are ERDAT and AEDAT which is created date and modified date.
fields for scheduling start date is tbtcp-sdldate.
Thanks in advance.
Ram.

Hello Ram,
Here you can check if updated date field is not empty then send status as created and if this field is not blank then send status as modified record.

Connecting to DirectAccess server from a client behind proxy with authentication

Hi,
All our DA clients are working fine except those that are working from a client company where a proxy with authentication is used.
Our DA server is running Windows server 2012 and clients are running Windows 7.
I have found similar posts, where it states it is a known issue and it is fixed by a new feature in Windows 2012, however i cannot find more info:
http://technet.microsoft.com/en-us/library/hh831416.aspx
IP-HTTPS runs in a system context rather than a user context. This context can cause connection issues. For example, if a DirectAccess
client computer is located in the network of a partner company that uses a proxy for Internet access, and WPAD auto detection is not used, the user must manually configure proxy settings in order to access the Internet. These settings are configured in Internet
Explorer on a per user basis, and cannot be retrieved in an intuitive way on behalf of IP-HTTPS. In addition, if the proxy requires authentication, the client provides credentials for Internet access, but IP-HTTPS will not provide the credentials required
to authenticate to DirectAccess. In Windows Server 2012, a new feature solves these issues. Specifically, the user can configure IP-HTTPS to work when behind a proxy that is not configured using WPAD and IP-HTTPS will request and provide the proxy credentials
needed to IP-HTTPS request authenticated, and relay it to the DirectAccess server.

Hello,
As far as I know it's a feature of Windows 2012 URA with a Windows 8 client.
Unfortunatelly you will have trouble with proxy authentication with Windows 7 client I think

Replacing MS ISA proxy with IronPort WSA proxy - ISA firewall client?

Replacing MS ISA proxy with IronPort WSA proxy - what about the ISA firewall client?
Does Cisco have an equivalent of the Microsoft ISA Firewall Client?
How does WSA handle complex protocols (such as ftp) through the proxy server?

We are replacing MS ISA proxy servers with IronPort WSA S370 proxy servers.
We have several apps that make use the MS firewall client.
The MS firewall client enables HTTP-tunneling of TCP & UDP through the ISA proxy servers instead of going through firewalls.
These apps use various ports - and there are rules setup on the ISAs specifially for these apps and their ports.
Also we have serveral uses of RPD, telnet, and SSH using the firewall client to HTTP-tunnel through the proxy servers -- and these have specific ISA rules setup for them too.
I can find HTTP-tunneling software - commercial and freeware - but can't find any that I think will work through the IronPort WSA S370 proxy servers.
Would like to find someone who has implemented HTTP-tunneling using IronPort WSA 370 proxy servers.
Thanks again for your input.

Can log into Yosemite server (4.0) VPN service with a Mavericks client, but not Yosemite client

Sever Info:
Yosemite Server 4.0 running on a late 2009 Mac Mini with 8 GB RAM with vpnd service enabled
The server was upgraded to Yosemite - not clean install - this may not matter (see below)
Airport extreme router with standard VPN UDP ports for L2TP forwarded to server (500, 1701, 4500)
Client info:
MB Air 13" early 2014 with 8 GB RAM
Yosemite
Mavericks 10.9.5 running as a Parallels virtual machine (don't ask - I need it to run an app for work that is not yet compatible with Yosemite)
OD service is NOT running - no VPN connections ever occurred from ANY client with this service running - OD is not needed in my case fortunately
With the OD service off, I can connect via the Mavericks virtual machine just fine, but not with Yosemite. With Yosemite, the ppp connection appears to occur, but server config requests appear to fall on deaf ears (client side doesn't appear to respond) until the connection times out. Can't figure out what triggers the client response to a server config request. Client side complains about no route to host and IP addresses don't get assigned to the connection.
The connection happens successfully in an eyeblink with the Mavericks client. Same username/password/shared secret in both instances.
Tried a generated .vpnconfig from the server, this also did not work.
It's possible that it is an auth problem, but can't figure out how the process occurs or what may be going wrong. There does not seem to be an obvious way to increase the granularity of the logging such that it might give other hints - at least that I can find. I found plenty of references to VPN issues when people upgraded from Mountain Lion to Mavericks as well as work arounds for this. I tried the most promising looking of those - no love. I reverted everything back to stock install since I could at least connect with Mavericks.
If log entries would be helpful, they are included below. I've stared at them long enough - perhaps a new set of eyes can provide a hint.
In addition, I can find no documentation regarding the VPN service in Yosemite server so as to get a clue as to whether there have been changes in racoon since Mavericks.
Thanks in advance for any suggestions. I would be glad to supply any other info needed for an accurate diagnosis .
Pat

2014-10-21 12:10:09 MDT   --> Client with address = 192.168.1.226 has hungup

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Any example of dynamic proxy with RMI?

Hi, are there any good example of dynamic proxy with RMI, using the new RemoteObjectInvocationHandler class?
I am currently implementing a Registry, and want to use dynamic proxy to wrap around the registry stub, to pass extra information to the client.
I've tried it, but the program will hang and get this exception:
Exception in thread "RMI TCP Connection(1616)-192.168.1.23" java.lang.OutOfMemoryError: Java heap space
My implementation looks like this:
public RegistryImpl extends RemoteServer Implements Registry {
    public RegistryImpl(int port, Properties... properties) throws RemoteException, ChannelException {
         // Create a reference for the registry.
     LiveRef liveref = new LiveRef(id, port);
        ref = new UnicastServerRef(liveref);
         Registry proxy = (Registry)RegistryProxy.newProxyInstance(
              this.getClass().getClassLoader(),
              this.getClass().getInterfaces(),
              new RemoteObjectInvocationHandler(this.getRef()));
         /* Using dynamic proxy */
         usref.exportObject(proxy, null, true);
public class RegistryProxy extends Proxy implements Registry {
     private InvocationHandler handler;
     public RegistryProxy(InvocationHandler handler) {
          super(handler);
          this.handler = handler;
     public Remote lookup(String name) throws RemoteException, NotBoundException, AccessException {
          Remote result;
          try {
               Method m = Registry.class.getMethod("lookup", new Class[]{String.class});
               result = (Remote)handler.invoke(this, m, new Object[]{name});
          } catch (SecurityException e) {
               throw new UndeclaredThrowableException(e);
          } catch (NoSuchMethodException e) {
               throw new UndeclaredThrowableException(e);
          } catch (Throwable e) {
               throw new UndeclaredThrowableException(e);
          return result;
     public void bind(String name, Remote remoteObj) throws RemoteException, AlreadyBoundException, AccessException {
     public void unbind(String name) throws RemoteException, NotBoundException, AccessException {
     public void rebind(String name, Remote remoteObj) throws RemoteException, AccessException {
     public String[] list() throws RemoteException, AccessException {
}I am new to Java programming, any help is appriciated.

Eddie

Hi Eddie,
Perhaps you might like this one:
http://wiki.java.net/bin/view/Communications/TransparentProxy
it uses dynamic proxies to achieve complete RMI transparency.
Something to consider, good luck.

Transparent design with router on both sides?

I am looking to solve a design which has to work in two scenarios. Preferably with an in-line solution.
1. Transparent design with VRF on both sides:
FW-VRF (Subnet A)
      |
      | (VLAN 11)      | ACE (Subnet A)
      |
      | (VLAN 12)
      |
LAN-VRF
      |
      | (VLAN 13)
      |
Real servers (Subnet B)
2. Transparent design in plain bridge mode
FW-VRF (Subnet A)
      |
      | (VLAN 11)      |
   ACE (Subnet A)
      |
      | (VLAN 12)
      |
Real servers (Subnet A)
As mentioned, I am aiming for a single design for both scenarios. A routed design will not pass in the first scenario and a one-arm solution will be inefficient in the second scenario. (both due to existing infrastructure) Is it possible to solve this with a transparent solution in both scenarios? I can't seem to get it to work.
Thanks in advance for any help!

I'm gonna expand my question a bit as I can not seem to get a working config in scenario 1. From the ACE I can ping the VRFs on both side of the ACE. I can on the other hand not ping neither the bvi-address of the ACE nor one VRF from the other. Can anyone notice any immediate errors in my config? Thanks in advance for any help!
Addresses:
10.3.66.1 - FW_VRF on client side
10.3.66.6 - LAN_VRF on server side

Transparent proxy & IP/IP gateway

I am trying to configure our BM3.7 system to us transparent proxy in
conjunction with IP/IP gateway.
I want to be able to take advantage of the caching features of the
proxy and
the access control of the gateway.
According to the install manual I must have the client configured with
the
IP gateway client software. However, it does not work correctly for
some
reason. The current proxy gateway status shows "No HTTP proxy server
found"
At one point I DID get a proxy server connection and things worked
great,
but for some reason I list it again after only a few minutes. ( I may
have
inadvertently changed a setting that screwed it up) Now, I can not
get ti
to work. Can any one give some suggestions?

OK, I think I have it.
I don't need the gateway. (Although the install PDF says I do)
From other article I see that the IP/IP gateway is no longer required
for
access control ( as the PDF states)

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?
What the RADIUS Server sees with ASA VPN auth - THIS WORKS OK (included for comparison)

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).
