Cisco 1841 match filter by string http requests

I have a web server behind a Cisco 1841 router that receives a lot of requests like follows(DDOS Slowloris), which causes the resource consumption of bandwidth and the server:

"POST/WP - login.php HTTP1.1".

On the web server, I managed using Iptables to stop these requests, but now I want to move this task to the Cisco 1841 router so that such requests stops at the front door and don't go all the way to the web server.

How can it be implemented in the Cisco firewall so that any request matching the string "POST/WP - login.php HTTP1.1" had to be abandoned?

Hello

Theres two ways to do that would work on a 1841 you can try anyway

SRW2048 and a Cisco 1841

I am trying to Setup VLAN between a 2 and a Cisco 1841 router SRW2048 switches. I have ports that connect the 2 switches to the other and the port that connect to router as junction ports. I set 2 VLANS. VLAN 1 is just the vlan by default everyone runs and vlan will be the area demilitarized. I have no configuration of access control lists to block traffic, but when I assign vlan 2 on the port that the server is, I can not ping to the gateway. I don't know what is happening, see below for the cleaned configs.

SRW2048 #1:

Port 1: Trunk (to the router)

Port 2: Trunk (SRW2048 #2)

Prot 24: VLAN 2

SRW2048 #2:

Port 1: Trunk (of SRW2048 #1)

Any ideas?

Because the SRW is now part of Cisco Small Business, it would probably be best to ask the Cisco Small Business support community. You find people from Cisco over there.

For SRW configuration, you added the two VLANS to your trunk ports? Configuration of a port in trunk mode adds automatically that all configured VLAN to the trunk.

The server has a static IP address in the DMZ LAN?

Cisco 1841 to Vigor VPN

Hi all

I desperately need help. I spent the last 48 hrs trawling internet try to find how to set up secessfully

I have port ports 80 and 443 forwarded for 78.25.xxx.xxx to our 192.168.6.65 local mail server. But all im presented with is unable to display the page when I try and connect to the external IP address on the local network. But if I try this address outside the local access network, then it works fine?

My other problem I have is that I would like to setup 7 vpn which all dial for this router. They are configured to use ipsec with a preshared key ike. The dial of the router are vigor 2600-2820 series and I was going to use the following configuration to the cisco but it crashes card crypto cm-cryptomap.

If anyone can help me I would really really appreciate it.

Cryptography works fine it seems.

The error you receive is I think because that side vigor is able to encrypt a subnet ip (range) that is not defined by Cisco.

The force he sends down to Cisco and after decrypting the Security Association IPSEC is a fall because it does not part of interesting traffic.

But, I guess you're already running.

L2l VPN with NAT static to hide the IP internal on Cisco 1841 ISR

I configured a VPN L2L on a Cisco 1841 ISR. I'm statically from some of my internal hosts to IPS that are included in encrypted traffic. Please note that not all internal hosts are underway using a NAT. I am doing this for hidden some of the actual IP addresses on the inside network. I confirmed that the VPN works as well as natives of VPN traffic. I configured VPN L2L traditionally on the Cisco ASA 5500 Series devices, and this is my first attempt with HIA of 1841. I want just the other to take a glance to see if I missed something, or could I effectively part of the configuration. All comments are welcome.

VPN between 2 routers Cisco 1841 (LAN to LAN)

Hello

I need to connect two offices (two different LAN) using routers cisco 1841 at both ends.

Currently the two cisco router are in working condition and refer the internet LAN clients. (making the NAT).

Can someone please tell us what is the easiest way to set up a VPN between two sites, so that LAN users to an office to access mail servers electronic/request to the office LAN.

I understand that I need IPSec Site to Site VPN (I think).

Anyonce can you please advise.

Kind regards.

Yes, you need a VPN site-to site. Start with this link which gives a number of examples to set up a VPN S2S between 2 routers Cisco.

How can I send a HTTP request to a web server using TCP?

I'm writing a HTTP string to activate a script CGI, server of our company. It seems that the OPEN TCP CONNECTION works. Can I just use the TCP WRITE function to send the HTTP request string to the server?
Thank you
Tim

I know that I probably would have finished faster if I had the Internet Toolbox, but the solution ends up being pretty simple with just the TCP features.
Here is the solution, I came with yesterday (in the case where someone else needs) after searching Protocols TCP as suggested by "Laboratory Viewer" and examine details in the riding of developer. It ends up being only a string of 4 line.

GET HTTP://proxyserver/path/file.asp?id=test HTTP/1.1
HOMEroxyserver

The first line of the string is made up of three things:
(1) the GET command
(2) the URL of the program target (in this case an ASP program that distributes a message preset)
NOTE that in this case, the URL contained "HTTP://proxyserver" and not only the path to the file. If your not using a proxy server, you can probably omit the name of the server of the URL, but you must always the name of the host server to the second line.
(3) the HTTP version used

The second line is the host server.

The last two lines are empty, but the two are apparently necessary to properly close the TCP request.

Vi uses an OPEN TCP CONNECTION to connect to port 80, then the 4 line string is sent with a WRITING of TCP and the connection is closed with a NARROW CONNECTION of TCP.

In my application, when the piece of equipment monitored by LabVIEW begins to enter a dangerous to use, LabVIEW uses this vi to send the HTTP request through the TCP connection and a program of target ASP on the company's web server. The ASP reads the message ID (? id = test) and sends the message page and the text messaging appropriate to maintenance and engineering personnel. People warned by text pagers are supposed to respond immediately.

Our DSI wrote the ASP that allows you to set the ID of multiple message with different distribution lists. Each message is triggered with a different ID of the virtual instrument according to the gravity of the situation.

Thanks to other amateurs who have published their questions and their answers. Hope someone else finds this useful.

signature of the oversized https request

Hi, is it possible that we can trigger an alarm when an https request exceeds a certain size?

I can define a type state.http signature using parameters such as the following? MaxRequestFieldLength takes into account the fragmentation of application data by ssl?

-Direction = ToService

-MaxRequestFieldLength = 1000000

-servicePorts = 443

-AlarmThrottle = FireOnce

-MinHits = 1

-ResetAfterIdle = 15

-ThrottleInterval = 15

-WantFlag = TRUE

If this does not work, would you please suggest alternatives. Thank you.

I looked into it, and it does not seem that this will really be feasible with the help of a personal signature. First, you must use the STRING. TCP engine for this. THE STATE. Engine HTTP needs context information in the HTTP stream in order to work properly. Because the HTTPS protocol is encrypted traffic, we have not these signals. So there's basically trying to count bytes in a HTTPS stream. Two problems here. First of all, the implementation of regex in STRING. TCP is limited to 512 ~ States for performance reasons. So, we will build only a model to 512 or more characters. This obviously does not follow the large desired patterns. Secondly, we need some sort of condition of single endpoint, a character model, at the end of the regex model with. Due to the random nature of characters in the encrypted HTTPS data, we do not have the guarantee that our terminator will not unexpectedly appear in the stream for giving us no good way to determine, we have reached the end of the search. This signature will probably be coded in a new engine.

How to use Layer 2 Ports on the Cisco 1841 router switch

Hello

I use the Cisco 1841 router with a single port layer 3 Fe0 and 8 Ports switched.

I gave the IP on the Fe0 port which is connected to another router.

Now I don't know how to use Layer 2 of the router switch ports.

I tried to make one of the port as a Port of access by switchport mode access and connected my laptop and the same subnet given IP, but I can't ping my Fe0 IP port and vice versa, as I am also unable to ping my laptop router.

Can someone explain to me how to use these ports on layer 2?

How to Setup Cisco 1841 as a site to site VPN VPN server, with watch guard

I would like to implement a cisco 1841 as a VPN server to establish s IP VPN (site to another) of a watch guard firewall,.

I have looked through some examples of cisco config, but can't seem to get a lot.

Can you please send me sample config steps I need o perform on the cisco router? and what credentials must be awarded to watch keeps establishing a permanent VPN?

emergency assistance will be greatly appreciated.

The cisco router is configured as a lan to lan normal IPSEC tunnel, there is no difference when configuration to create a tunnel to a watchguard/sonicwall or all that peer will use, you can use this link as a guide:

Please help, how to set up vpn?

Hello

According to this output is more than clear that you do not have a k9 license applied to this router, this license will enable the security features on your IOS, in this case, you will need a permit of k9 with an activation key, and then you will be able to have available on your device encryption controls. Once you have that we can work on configuring site to site.

Do not forget to rate!

Trying to prevent the firewall to respond to Https requests

Current configuration

-2 x ASA 5505 firewall, running 9.0.4; ASDM 7.1; Active mode / standby

-With the help of Anyconnect v3.0.3054

-VPN using IPSec only; SSL access is disabled.

-Anyconnect manually installed on laptops.

-Web portal Shutdown and the browser not found poster

-Clientless SSL VPN is disabled.

Here's my problem: (this problem is causing my external PCI analysis to failure, it is a failure because the https site use ssl3.0 or TLS 1.0)

1. from an external PC, I open any browser and go to the IP address of my firewall (e.g. https://8.8.8.8)

2. the browser gives a warning about an untrusted certificate.

3. If I click on continue, then the browser tries to go to the Web portal connection but then shows the "Cannot display Page" page

What I'm trying to do is to stop the firewall to respond to HTTPS requests to the address of WAN IP in the firewall; If I do step 1 of my problem, I want the browser timeout due to no response from the firewall.

After reading the manuals of the admin and research on this problem, I hit a wall.

Thank you

VPN IPSec (IKEv2) remote access requires the use of SSL for the creation of the first session. As much as I know there is no way to avoid. You should explain to your listener that this is necessary and that the absence of other services on this interface is a control to compensate for the use of SSL.

Cisco 1841 how vpn tunnels? default 100vpn?

Hi everyone, I have read the previous posts and I read that the cisco 1841 can manage up to 100 default VPN tunnels.

1. is this true? (I enclose my worm of show)

2. this version of IOS support SSL VPN tunnels as well?

Hello

I guess that means that the total number of vpn ipsec tunnels taken in charge by the router of SSL VPN AIM is 800.

If you want only a SSL VPN without the AIM module can it be based on the license.

Kind regards

How to get AFExecuteThisScript to return the value of Net.HTTP.request (asynchronous)?

I have an Acrobat only plugin, developed in 2005 VS. Originally with Acrobat 7 SDK, now updated to use Acrobat 9 SDK. The ultimate goal of this feature is to open a PDF file from a web server Agile: If a user string, a URL is created, a request sent to the URL, then pay back the answer. The answer can be either the PDF itself or a string path to the PDF file. I thought it would be easier to use the version of PDF path to simply open the new PDF of the http:// address.

I created a folder level javascript with a call to Net.HTTP.request confidence. I have a script that works when invoked from a menu item added by the folder level javascript file. But when you use this same command in my C++ with AFExecuteThisScript code, I can't get the HTTP response to finish pending in the code for the result.

The Net.HTTP.request and the asynchronous callbacks confuse me, so maybe that's my big problem. I could not Net.HTTP.request to return a value in a service simple javascript right now, I'm trying to use a "global" variable in the JavaScript folder level and two calls. The first call "sets" the global variable, the other "becomes" it. But this seems to be the issue. When I have my code debugging or stop execution, the part of the response of the Net.HTTP.request is never called. But when I left to go beyond this step with error recovery, the answer appears later.

So how kick off of the Net.HTTP.request and be notified when it's over? either in JavaScript or VC ++?

Any help is appreciated. Even if the best option is to stream the file from the web server to a local file and then open the (this is the option that I take in another tool that runs outside of Acrobat).

Here's the code.

Javascript controls at the level of the files (urls truncated for the post)

var THE_PATH = '';

function setTHE_PATH ( gURL ) {
    console.println('setTHE_PATH Begin');
    var params =
    {
        cVerb: 'GET',
        cURL: gURL,
        oHandler: 
            {
                response: function( msg, uri, e)
                {
                    console.println('response method: Setting Path');
                    THE_PATH = SOAP.stringFromStream( msg );
                    console.println('<<' + THE_PATH + '>>');
                }
            }
    };
    console.println('URL: ' + params.cURL + '\n  oHandler: ' + params.oHandler );
    console.println('Path: ' + THE_PATH );
    var netResult = trustedNetHTTPrequest(params);
    console.println('setTHE_PATH End');
    return THE_PATH;
};

trustedNetHTTPrequest = app.trustedFunction( 
    function ( params ) {
        console.println('trustedNetHTTPrequest begin');
        app.beginPriv();
        var netResult = Net.HTTP.request( params );
        app.endPriv();
        console.println('trustedNetHTTPrequest end');
        return netResult;
    }
);

Added MenuItems with JavaScript at the folder level

app.addMenuItem( { 
    cName: "mysetTHE_PATH", 
    cUser: "set THE_PATH", cParent: "Tools", 
    cExec: "setTHE_PATH('http://......&getURL=true');",
    nPos: 0 
} );    

app.addMenuItem( { 
    cName: "mygetTHE_PATH", 
    cUser: "get THE_PATH", cParent: "Tools", 
    cExec: "console.println( THE_PATH );",
    nPos: 0 
} );

Here's the JavaScript Console output when you run these two commands:

setTHE_PATH Begin
URL: http://......&getURL=true
  oHandler: [object Object]
Path: 
trustedNetHTTPrequest begin
trustedNetHTTPrequest end
setTHE_PATH End
response method: Setting Path
<<https://......DesiredFilename.pdf>>

Here is the function in the plugin C++, with additional measures to prove AFExecuteThisScript works here

sprintf(jsScript, "testVal='%s';event.value = testVal;", strURL.c_str() );
AFExecuteThisScript( aPdDoc, jsScript, &pReturnValue );
// After this, pReturnValue is the passed-in URL, as expected.
sprintf(jsScript, "setTHE_PATH('%s');event.value = 'Step 1 Worked!!';", strURL.c_str() );
AFExecuteThisScript( aPdDoc, jsScript, &pReturnValue );
// After this, pReturnValue is 'Step 1 Worked!!', as expected.
sprintf(jsScript, "event.value = THE_PATH;", strURL.c_str() );
AFExecuteThisScript( aPdDoc, jsScript, &pReturnValue );
// After this, pReturnValue is NULL

This is the JavaScript Console output when you run the commands using the plugin (mode debugger, to wait after step 1)

setTHE_PATH Begin
URL: http://......&getURL=true
  oHandler: [object Object]
Path: 
trustedNetHTTPrequest begin
trustedNetHTTPrequest end
setTHE_PATH End

Note that he never gets to the part of the "method of response.

Thank you!

You need not limit yourself to the plugin API. The requests HTTP from C/C++ is a fairly common condition, just observe the restrictions in my answer.

Cisco 1841 match filter by string http requests
