Cisco Application :: ACE 4710 Giving Mangled Http Requests In Apache Access

Oct 21, 2012

After replacing a Cisco CSS/SSL  Accelorator and PIX firewall with an ACE 4710 to do load balancing and  SSL encryption behind an ASA firewall we started seeing mangled HTTP  requests in the Apache access logs for the servers in the server farm. This is occurring for several different URLs and not just the one above and for multiple web browsers.The ACE load balances to servers running Tomcat 7 with Apache HTTP server v. 2.2.14. A recent ACE software upgrade to A5(2.1) has not fixed the problem.

Cisco Application :: ACE 4710 Deployment - Load Balance HTTPS Requests From Internet

Oct 17, 2012

I’m looking for some notes from the field guidance here from those that have much more deployment experience.
 
I have a GSS and an ACE, and its the ACE that's primarily giving me something to think about, in terms of placement and what mode to adopt.
 
The traffic flow will look loosely like this:-
 
Client---Internet---Firewall---GSS---ACE---Servers
 
Physically, it's like this. The RED line denotes a boundary, and pretty much anything North of that is not accessible to us, we simply have a L3 trunk between our switches and "their" switches (S3/S4) and talk using EIGRP.
 
There are other servers in the top tier, some that also require load balancing, some that don’t. Typically, I want to load balance HTTPS requests from the internet, to one of the 3 servers in the top half.
 
I’m not sure what mode to select, routed, one arm? What about placement of the ACE? At the moment, I’ve just configured 1/1 on it and made it part of the MG MT VLAN, it's S VI exists on the S1/S2 switches, so I’m open to change as it's still all in the lab.

Cisco Application :: Insert Http Header Ace 4710

Jan 9, 2013

I have an ACE version A5.2 configured in one-armed leg (doing source nat). I have a requirement to add(or copy) the "referer" header value from the original request to the request send by ACE.
 
I cannot figure out how to copy this value. It is easy to add the source ip address  by adding: " insert-http x-forwarded-for header-value "%is".
 
So how I am going to copy the Refere header?
 
#Referer
#Address (URI) of the resource from which the URI in the request was obtained

Cisco Application :: CSS Or ACE 4710 Redirect HTTPS To Http

Feb 27, 2012

For a CSS with a SSL module (performing SSL termination) - is it possible to impliment a redirect on https URL to send to equivalent http URL.If my understanding is correct, the CSS will do SSL termination and then use an http content rule on the resultant http stream as it is recursively handled by the CSS ? This would mean that the SSL module has no way of seeing/acting on layer 5 and above data (i.e. picking up on a specific URL) and can not itself issue a redirect - i.e. you could not associate a redirect statement or service with the following ssl content rule ? [code]The CSS would instead rely on a http content rule to impliment a redirect - i.e. you would have to associate a redirect statement or service to the following http content rule instead?
 
But if the CSS is already handling traffic for existing url...  traffic that is going to cause a loop when a client goes direct to. url...I realise the requirment is uncommon / a bit convoluted, its one of those don't ask type scenarios - aimed at achieving a specific requirement.Would the ACE 4710 be able to handle such a scenario any differently ?

Cisco Application :: IOS HTTP Authorization Vulnerability When Traversing ACE 4710

Oct 10, 2012

We had a PCI security audit of an existing VIP on our ACE 4710. The VIP is set up as HTTPS terminating on the ACE with a http redirect for all 80 traffic.  The audit reported this VIP was vunerabled to the Cisco "IOS HTTP Authorization Vulnerability".  Which basicly states, http Management is on this IOS device.  It does not make any sense, as the VIP is pointed to a pair IIS servers?

Cisco Application :: 4710 - HTTP-Cookie Sticky Not Working

Feb 1, 2012

I have a requirement to load balance OWA 2010 inbound connectivity to 2 CAS servers using a ACE 4710 with sticky sessions enabled.
 
The CAS servers are currently responding on 80 or 443 at this moment in time. Eventually I want to off load the SSL to the ACE 4710, its currently running on the CAS servers. I need to enable sticky sessions to keep the session to the same CAS server for each internet based connection. I also have a proxy enabled for inbound connectivity so I cannot use source IP.
 
Here is my configuration but it doesn’t seem to be working, i am currently testing with port 80 connections not SSL.
 
serverfarm host INHOUSE-EXCHANGE-OWA-vFARM
predictor response app-req-to-resp samples 4
probe 443
probe HTTP-PROBE
rserver INHOUSE-TEST-CAS01-SVR
   inservice(code)

The https is working but i have a problem. when i access the Main link "first" it is redirected to https to the Main link.But if i access one of the Sublinks directly(without having to click on the main link first) the page is redirected to https but to the Main Link. i have to click the Sublink again in order to get the page.How can i redirect to https and stay on the same page? What might be the general link in the webserver-redirection?

Cisco Application Networking :: ACE 4710 - How To Configure HTTP Rewrite Request / Response

Sep 18, 2011

We want to mask part of the path prefix to hide development content: For example: the site(s) are: [URL]However we don't want anything with acme showing...so we would want the loadbalanced url to be: [URL] ...for requests and responses. I think this would be an http re-write request/response scenario?Is this possible to configure this on the ACE Device? We've got the load balance configuration down...not sure how to do this re-write type scenario?

Host Website With Apache HTTP Through ZyXEL EQ-660R Modem?

Dec 21, 2010

Essentially, I have a spare desktop computer I'd like to turn into a web server, but my modem and wireless router are very difficult to work with. I installed Apache HTTP and successfully hosted a test page which can be accessed anywhere on the LAN. However, I'm having trouble setting up the server to be accessed from my external IP address.

I was supplied with a ZyXEL EQ-660R DSL modem by my ISP (CenturyLink) and bought a Netgear WGT624v3 wireless router in which to connect my laptop and spare desktop.

ZyXEL's website is not useful, and I don't think much of the problem is with the Netgear router. I've played with many settings and have tried to forward port 80 from the modem, but I've had no luck.

Cisco Application :: 8009 L7 Ace Configuration Replace Apache AJP

Jun 26, 2012

i am trying to use teh ACE to replace an apache based load balancer in an jboss application cluster. I am using L7 loadbalancing to load balance between multiple components. the way these jboss application servers work with apache is that.When the jboss application starts up on the on application cluster, it issues a GET opencase/webservices/config-service?wsdl to the loadbalancer IP.The apache based LB in turn talks to the same box on port 8009 via ajp retrieves the configuration file and provides it back to the application on port 80.And after 2 has completed the Jboss application comes up. Basically to start the application the Apache loadbalacer will accept requests from the its target list and load balance the request back to them itself.Not sure how i can use the ACE to accomplish this. attached are my topology (logical) and the ace configuration. from my topology file -- the net-cms-1 will issue a get request to teh VIP (on the ace), the ACE accepts the connection but soon resets it.

D-Link DIR-655 :: How To Forward Requests To External Http-Proxy

Goal: To forward requests over port 80 from my LAN to an external server on a specific port, that is I would like to forward all requests over http to an external proxy.

I know that this can be done with IP-Tables, but I would like to do the same thing with my D-Link. I have looked at Advanced --> Routing, but that seems to be specifically for inbound requests. I want to do this for outbound requests. This can be achieved with the D-Link DIR-655?

Cisco Application :: Unable To Access Server Through VIP (ACE 4710)

Oct 3, 2012

configure Cisco Ace 4710 ?Note :- Just a testing face I need to access my one server(192.168.1.11 : 80) through VIP :- 10.13.77.10 ,    I have only one Cisco Router 2800 and One L2 Cisco Switch 2960 and Cisco Ace 4710 . So I already configured 2 Different VLANS in Switch (Vlan 10 & Vlan 100) and by router I given the ip address of that Vlans with Inter Routing Vlan. My Connectivity is like this :-- Router Ethernet 0/0 --- 10.13.77.1/24 with vlan 10) & Router Ethernet 0/1 ---- 192.168.1.1/24 with vlan 100 ) connected with switch after that I configured ACE LB and connect the ACE interface with switch Like that ---- Connect to ACE Interface 2/3 vlan10 with switch vlan10(Ethernet port  2-12) and  Connect to ACE Interface 3/3 vlan100 with switch vlan100(Ethernet port  13-24) .Testing to access server from Switch Vlan10 to Vlan 100 where my server is there.
 
Configuration :---

ACE>  client side Vlan10 (10.13.77.4/24) , VIP :- 10.13.77.10, SM-- 255.255.255.255
 ACE>  server side Vlan100 (192.168.1.5/24), Web server -- 192.168.1.11 with 80 port
 ACE> Managment Vlan 1000 (172.16.6.5/24) ,
 ip  route 0.0.0.0 0.0.0.0 10.13.77.1
 
 I already Configured in Routed mode but From Vlan10 ip subnet example like 10.13.77.12(Client or User PC) tried to access server 192.168.1.11 with VIP http://10.13.77.10 but not responding , if i access server with real IP then accessible (why boz there is inter vlan routing)?

Cisco Application :: ACE 4710 - Cannot Access Management VLAN In Context

Jan 21, 2012

I have an HA ACE deployment and all seemed to be working well until I tried to access the ACE via the management VLAN in the one non-system context, no go.The ACE is in one-armed mode with an Admin/System context and one user context (named Messaging).  Source NAT has been set up in the user context.  All VLANs are in a port channel back to the core switches.I can access the ACE via the Management VLAN in the system context, all OK.  I can access the load-balanced servers via the VIP in the user/Messaging context, all OK.  I CANNOT acccess the managment VLAN other than ping it (resonds to ping, but telnet, ssh, https, etc. fails).The system/Admin context has a default route to the Management VLAN on the core.  The User/Messaging context has a default route to the core switches on VLAN 5, which is the VLAN where the VIP resides.If I change the default route in the User/Messaging context to the Management interface on the core switches then I can access both contexts for management, but then the load-balancing falls over and I cannot access the serverfarm (via the VIP).  Traces on the rservers show that NAT is being hit on the ACE and the requests are coming from the real IP of the clients.  Put the default route back to the User/Messaging VLAN on the core and NAT is back to what it would be expected to be, and then remote/management access to the ACE is gone.

Cisco Application :: ACE 4710 No Access To Any Server To Do File Transfer

Jan 26, 2013

I ma having issues trying to import a .PEM file into an ACE 4710. The original file was a PCKS12 file that was converted to a set of .PEM files as I have no access to any server to do a file transfer. This has worked in the past. the error I get is "Error: File not of recognized types - PEM, DER or PKCS12, import failed". I am not sure what is exactly failing. The cert was converted to a .PEM and the ACE imported that fine.

1337 / Apache - How To Access NodeJS Server On LAN

Apr 10, 2013

i've created an application with NodeJS and I'd like to test the application on my LAN with my family. The application listens on port 1337 for connections and I can access the application fine through my own PC by typing localhost:1337, 192.168.0.3:1337 or even http://joel-pc:1337/ into my browser's address bar.

I will be also be running apache alongside NodeJS, and I can access this fine by typing 192.168.0.3 or http://joel-pc/ into a browser's address bar as long as it's connected to the same network.Now here's the weird part; If I stop the apache service, change my node application to listen on port 80 (http) insted of 1337, it will be accessible on my pc by typing localhost, 192.168.0.3 or even http://joel-pc into my browser's address bar. However, I still can't access NodeJS on any other PC on my network apart from my own.

I've tried creating an outbound rule within Windows 7 to allow access to port 1337, but I still can't get access to my NodeJS server on any other PC than my own, even if it's listening on port 80.

1)  What impact will this have on the CPU?
2)  What impact will this have on Memory utilization?
3)  Is there a maximum nubmer on redirects?
4)  Are there other things I should be concerned about?

The problem is that when the application wants to update the server it does it with the name.Doing some research I found that you can rewrite the record DNS based on the static NAT you set up on the ACE. The feature is called DNS inspection. Is the same feature as the ASA (DNS doctoring).I apply it to the outside interface and it did not work.
