Cisco ACE SSL termination
Hello Friends,
Need ur help on cisco ACE SSL termination.
If i import the certificate and key (.PEM), where this files will be saved ?
can we able to download the .PEM file any time as we need(back-up)?
suppose if my .PEM is got hacked, hacker is sniffing the data packet which going through the web server, can it be possiable to deencrypt the packet and see the exact packet ?
Regards,
Naren
Naren,
1. In order to import certs and keys, please see the following link to the command reference. To summarize, any time you import/export/delete keys/certs, you are doing so via commands in exec mode. Regarding how and where the ACE actually saves this information, I do not know this answer.
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A2/command/reference/execmds.html#wp1616651
2. You can import a key as non-exportable if you do not want it to be able to be exported. If you import it as exportable, you can always export it later for backups or what not.
3. You can decrypt captured HTTPS traffic if you have the private key. It is important to limit access to it. Please see this link for more info on using Wireshark to view decrypted HTTPS traffic: http://wiki.wireshark.org/SSL
Hope this helps!
Regards,
Matt

Someone can help me to understand why is not working ?
for further information please ask me
Thanks a lotHi,
The problem is here:
class-map match-all example_IT_HTTPS-HTTP
2 match virtual-address 22.235.121.6 tcp eq www
You should change it to 443 instead of WWW which means port 80.
You will never match this class "example_IT_HTTPS-HTTP".

note: Subnet, Server Name, Certificate Name and Key Name are modified for security reason.Hello,
We will not be able to determine why your SSL terminated connections fail with only your config. You may want to take a look at a similar thread where someone else was having problems with IE and SSL termination, but Firefox worked fine. It also includes a solid action plan you can use to gather data needed to diagnose root cause. That thread can be viewed at the following link:
https://supportforums.cisco.com/thread/2025417?tstart=0
Also, the ACE software you are running is extremely old now and very buggy. I would strongly urge you to upgrade to A2(2.4) as soon as possible. It will help you avoid some headaches as you move forward.
Hope this helps,

Cisco ACE SSL Offloading not working
Dear All,
I have configured SSL offloading on ACE when i tried to test it from the PC i found that:
1. when i try to test the SSL Offloading by (https://192.168.69.110) i can reach the main page on WEB1 but i can't open any virual directory or any link inside this server (ex: https://192.168.69.110/web).
Thanks,
BaderHello Mohammed,
The behavior which you are getting is totally expected since you are NOT matching the url.
Why do not you try this?
(config-cmap-http-lb)# class-map type http loadbalance match-all MATCH-URL
(config-cmap-http-lb)# match http url /.*
class-map type http loadbalance match-all MATCH-URL
2 match http url /.*
Also you can try this one instead of the one above, since this one will be more specific:
class-map type http loadbalance match-all MATCH-URL
2 match http url /web.*
policy-map type loadbalance first-match WEB-SERVERS-LB
class MATCH-URL
sticky-serverfarm Sticky-WEB-SERVERS
class class-default
sticky-serverfarm Sticky-WEB-SERVERS
Please mark it, if it fixes your issue.

ACE: SSL termination, Probe and Redirect problem
Hello,
I have problem with three things: -1) SSL offload, -2) probe, and -3) server redirect.
1) I made SSL offload like shows attached file with "show run". But during going to the VIP address by the browser: https://192.168.254.143 I get window with Java error: java.lang.NullPointerException - I have to click OK on this window and then can work fine. Without SSL offload I don't have this error message in window.
When I have SSL offload I have following configuration:
ssl-proxy service SSL
key klucz.pem
cert certyfikat.pem
serverfarm host SFARM
rserver S1 8080
rserver S2 8080
policy-map multi-match SLB-POLICY
class SLB
ssl-proxy server SSL
Without SSL offloading I have only this:
serverfarm host SFARM
rserver S1 (without 8080!)
rserver S2
2) Right now I have two real servers and I send traffic to them by port TCP 8080. So I made probe to check TCP 8080 port availability.:
probe tcp TCP_8080
port 8080
interval 15
passdetect interval 60
serverfarm host SFARM
rserver S1 8080
probe TCP_8080
inservice
rserver S2 8080
probe TCP_8080
inservice
I want also check port TCP 6400 availability, and I only one from port 8080 or 6400 don't work - make real server unavailable. So must work TCP port 8080 ang 6400 togethet to treat real server as operational.
So I want to make something like this:
probe tcp TEST
port 8080 and 6400 !?! - ofcourse It is impossible but I want to make config with this functionality.
How to do this?
3) I hant to make that when I write in browser https://bo.kw.coig.biz/ = https://192.168.254.143 I want to be redirected to one of real server on address: https://bo.kw.coig.biz/businessobjects/enterprise115/desktoplaunch/InfoView/logon/logon.do
I made something like this:
rserver redirect S3
webhost-redirection https://%h/businessobjects/enterprise115/desktoplaunch/InfoView/logon/logon.do 302
inservice
serverfarm redirect REDIRECT
rserver S3
inservice
policy-map type loadbalance first-match POLICY-TYPE
class class-default
serverfarm REDIRECT
But this configuration dosn't work. I have in browser window with error messeging.
How to do this?1/ this is a java problem.
Java is telling you that it attempted to use a null pointer. You need to check with the people who created the java program
2/ you can configure multiple tcp probe, one for each port you need to monitor and assign all the probes to the serverfarm.
BTW, you can assign the problem to the entire serverfarm so you don't need to specify it for each rserver.
3/ the problem with your redirect is that you applied to class-default.
So even a request to ...../logon will be redirected to ...../logon.
Therefore you just created a nice loop.
You need to create a class-map to only match the url "/" so the redirect is only applied then.

ACE: HTTP followed by HTTPs/SSL termination, stickiness
Dear Helpers,
I'm trying to figure out the best sticky/persistence method for the following for ACE,
Client X ----(HTTP)--------------------------------------------ACE LB ---to----Server 1
Client X -----(HTTPs)---ACE/SSL termination ------ACE LB ---to---- Server1
Both HTTP and HTTPs use the same VIP for HTTP and HTTPs)
The same client to stick/persist to the same server using both HTTP and HTTPs. HTTPs/SSL is terminated by ACE.
Could you point me to sample configurations for this requirement, please.
Thank you
SSHI Gilles,
thanks for the response. Sorry had gotten distracted with a bunch of other things, didn't get a chance to get back to this. Anyway, so, I can generate the 302 response in my web-servers except I need to turn it around to a different domain name. Now assuming I use URL re-write when I see this coming back from the web-server, I can rewrite this to https and send to the client? A few questions about this and the links you sent above with using redirect service.
a) can I do a a redirect to an https address or does it only do http (considering I only saw examples configs only using www.domain.com/index.html type redirects without specifying the protocol to use)?
b) If not, then I use URL rewrite in conjunction with the 302 from the web-servers. But for my SSL off-load in a pair of CSS using VIP and Virtul Interface redundancy, do I buy 2xSSL Certs for the same domain-name or do I buy ONE (i.e. generate the key-pair/CSR in Master CSS) and import the same rsakey and SSL Cert recd. from CA into both CSSs?
c) Does the CSS handle a wildcard SSL Cert without problems?
Thanks again,

SSL Termination not working in ACE
Hi,
The context was configured for Load Balancing Port 80 and 443 traffic before the SSL Configs was Applied.
The SSL Termination is configured on ACE module running the software version A2(1.6a) [build 3.0(0)A2(1.6a)
The load balacing is working without no issues, But when i do a https://abc.www.abc.qa/wps/portal/login
the browser reconganizes the certificate from ACE, but does not show up any thing, just shows this symbol €
in a blank page.
Plese let me know if you have any suggestions.

SSL Termination in ACE 4710 not working
Hi,
I have configured a new ACE 4710 with only a sinlge context to redirect https traffic to http real servers using SSL Termination. When I do a telnet on port 443 or 80 to the VIP it works fine but when I try to open the URL it prompts me for accepting the certificate then it tries to find and establish connection to the URL but eventually dies out giving a "Page cannot be displayed error". I have done some troubleshooting and found that the connection to the VIP on 443 port is Established but the out connection from the real server to the client remains in the INIT state. I am attaching the configs and all the troubleshooting data I have collected. Pls someone help.Yes the "server pkt count" for the "class: VIP_HTTPD_Redirect" is not incrementing and yes the servers do not have the default gateway towards the ACE.So as suggested I have configured default route in the servers towards the ACE interface vlan ip address. Still the server packet count is not incrementing. I am posting the updated configuration of the ACE as an attachment. Pls help.

Cisco ACE - Exempt HTTP URL from SSL Offloading
Hi,
I have a cisco ACE module A2 (3.6). I am offloading url www.abc.com on cisco ACE. HTTP redirection to https is working & over https I am able to browse website perfectly. real servers are redirecting some pages over http. Due to page redirection from webserver I have to exempt one URL (http://www.abc.com/modules/docs/abc.aspx) from ssl offloading. It is possible or as a work around i have to rewrite complete url www.abc.com as ssl port.
Your inputs highly appreciated.
Regards,Hi Masif,
In case you have not gotten assistance with this one, you just need to specify the specific URL and match it on top of the loadbalance policy that is already doing the redirection.
class-map type http loadbalance match-any No-Redirect
2 match http url /docs/abc.aspx
policy-map type loadbalance first-match ABC
class No-Redirect

Hope this helps.

----------+--+---+-----+----+---------------------+---------------------+------+Hello Alvaro,
The issue here is that your config is missing the clear text port the ACE should use to send the traffic to the backend servers; in this case port 80.
Remove the rservers from the SF "farm-demo" and then configure them back like this:
serverfarm host farm-demo
rserver rsrv1 80
inservice
rserver rsrv2 80
inservice
That should do the trick =)

SSL termination and URL redirection
Hi All,
I have configured application in cisco ACE module for which i got more requirement for URL redirection.
Application setup is as below.
VIP : 10.232.92.x/24 which is pointing to 2 Web server 10.232.94.x/24 range. In addition to that app team want APP server also need to be loadbalanced hence new VIP is configured for 10.232.92.x/24 which is pointing to 2 different app server 10.232.94.x/24.
Both Web and App servers are having different IP but in same broadcastdomain. SSL termination is done on ACE.
Issue : 1) After initiating connection i am getting login page but after login its again giveing login page. After 2 to 3 trial its giving me application page but with invalid session error.
2) How to do https connection redirecting to different path.
Ex. https://apps.xyz.com to https://apps.xyz.com/abc
configuration :
probe tcp rem_app_tcp
port 2100
interval 5
passdetect interval 10
passdetect count 2
open 1
probe http rem_itsm_https
port 80
interval 5
passdetect interval 10
passdetect count 2

We have a new secure site where we are using the ACE as a ssl-proxy. I see connections make it all the way to the servers, but the session eventually times out (Browser responds with "The connection has timed out"). I haven't been able to grab a packet capture yet, but I am looking for some input since I am new to the ACE. We are also set up for sticky connections using cookies.
I see connections to the server but no response back. I also see the cookie places in my browser. Once I close the browser window, the current connection drops.
sh serverfarm SECUREMAIL
serverfarm : SECUREMAIL, type: HOST
total rservers : 2
----------connections-----------
real weight state current total failures

10.0.0.95:8080 8 OPERATIONAL 1 4 0
rserver: E02
10.0.0.98:8080 8 OPERATIONAL 0 1
I verified the cert and keys match with the verify cryto command. If I bypass https and connect via http, I am able to hit the server test page. I attached the scrubbed config.
Any info is appreciated.Make sure clock on supervisor/device has correct date to avoid not before not after check of cert.
Once the configuration is complete, check to make sure the VIP address can be accessed via HTTPS in a web browser. If any certificate errors are shown, this indicates a problem with the certificate, not with the Cisco ACE configuration. The above commands can be used to verify that SSL sessions are being terminated successfully.
When a client’s web browser connects to an SSL server on any device, the browser and server negotiate which encryption cipher to use for the session. The list and order of ciphers presented by the ACE in a default configuration are as follows.
1. CM_SSL_RSA_WITH_RC4_128_MD5
2. CM_SSL_RSA_WITH_RC4_128_SHA
3. CM_SSL_RSA_WITH_DES_CBC_SHA
4. CM_SSL_RSA_WITH_3DES_EDE_CBC_SHA
5. CM_SSL_RSA_WITH_AES_128_CBC_SHA
6. CM_SSL_RSA_WITH_AES_256_CBC_SHA
7. CM_SSL_RSA_EXPORT_WITH_RC4_40_MD5
8. CM_SSL_RSA_EXPORT1024_WITH_RC4_56_MD5
9. CM_SSL_RSA_EXPORT_WITH_DES40_CBC_SHA
10. CM_SSL_RSA_EXPORT1024_WITH_DES_CBC_SHA
11. CM_SSL_RSA_EXPORT1024_WITH_RC4_56_SHA
If this list is not desirable or the order needs to be changed, an SSL parameter map can be configured to make such changes.
Can you send the output of the following commands to suggest more on your config
ACE-1/routed#show crypto authgroup all
ACE-1/routed# show conn display 1000 detail
ACE-1/routed# show crypto files

ACE SSL Offload Advantage on End to End SSL
Is there any advantages to doing SSL termination on ACE if you are doing End to End SSL? It seems as thought it's just another place to manage certs, when you could just pass the port 443 traffic to the server and let it do the SSL decription/encryption.
centralized point of management of your certs
performances (hardware-based)
you can use strong ciphers on the client side and weaker ciphers on the server sides, reducing the load on the servers
use of SSL Reuse combined to TCP offload
There are some whitepapers available on cisco.com on this topic. -
Sticky session for SSL termination
We have a server farm with 2 servers. The ACE is perfoming SSL termination to this farm, and talking tcp/80 on the back end. How can I ensure these sessions are sent to the same servers?
Thankssince you are doing ssl termination you can do cookie sticky and have the ace either learn a cookie from the server or insert a cookie to provide sticky.
for instance to do cookie insert
sticky http-cookie COOKIE1 GROUP3
cookie insert browser-expire <-- this makes it a session based cookie. If you want the cookie to expire at a set time you can leave off browser-expire
and then set a timeout . the timeout is not on ace rather we will send a utc expire time to the browser
serverfarm test
then call the sticky serverfarm in your load balance policy
policy-map type loadbalance first-match L7PLBSF_STICKY-COOKIE_POLICY
class class-default
sticky-serverfarm GROUP3
you can also use other sticky methods see
