Layered ASM for APM login page protection
Has anyone successfully implemented https://my.f5.com/manage/s/article/K000149701 Full VPN clinets stop working after this implementation. I can see below errors Client machines interface IPs are not falling under a private subnet or exception subnet ranges provided by the APM server The connected network is vulnerable of tunnel crack as LocalIP falls under the public IPs
Recommendation for Adv. Lab
Hi Everyone, I'm relatively new to F5 BIG-IP and want to improve my hands-on skills. I have a chance to build a good lab, but I'm struggling to find real-world use cases and troubleshooting scenarios. Currently, I can only run basic tests with DVWA, but I want to simulate a complex environment. Could you recommend any resources (videos, docs, or lab guides or anything can help) specifically for LTM, AWAF, DNS and APM, use-case scenarios, troubleshooting exercises, architectures etc. Any guidance to help me bridge the gap between basic setup and professional practice would be greatly appreciated. Thanks in advance!
APM Policy loses POST request content when forwarding across multiple domains.
We have a problem like this, the AAA domain looks at the external side, we forward the requests from the outside to a virtual server located in the CCC internal domain as a policy base. We are authenticating with an apm policy with an internal server multidomain, but we lose the content of the incoming post request while forwarding. Of course, while the POST request is forwarded, GET returns, it catches it and POST is translated. However, the content disappears in the meantime. Is anyone having this problem?OCSP AUTH AGENT
Hello everyone, I'm facing a situation and I need your input to figure it out what's wrong. I have a VIP where mtls is configured in the client SSL profile with the issuer's certificate as CA (we call it CA_1), and it works well. (Per info, the client cert is issued by CA_1, which is also issued and signed by a higher authority CA_2.) I wanted to make OCSP checks for client certificates so I created a simple APM policy as follows : Client --- > on-demand cert agent ---> OCSP Auth Agent ---> Allow or deny The OCSP responder is configured with the same CA_1 that's configured in the in the Client authentication in the ssl profile, and a responder (ocsp.example.com). The error I'm facing is OCSP Auth agent: Failure status 'Error querying OCSP responder host ocsp.example.com. To troubleshoot, I did few tests and we can eliminate the following possibilities: Connectivity and DNS: I can reach the responder in the http port using the FQDN. Blocked traffic : no Firewall inspection between the BIG IP and the responder. The responder is not treating the request as it should: openssl ocsp verification works fine and gets me the wanted result from the ocsp responder. The famous "missing host header" : the header is well included in the request sent by the big ip to the responder; moreover, i compared this request to the one sent when using openssl ocsp and the one sent when i test from my own computer using openssl, and they are identical when it comes to the OCSP date in the request and response frames. What's more interesting is when I capture the response sent by the responder when the apm sends the ocsp verification request, i can clearly see that's stating the status of the certificate (which is revoked in my case), but the APM logs doesn't show that; instead, when debugging, it says that the on-demand cert agent is executed (i can see the client cert and the issuer cert CA_1 as well) and then it moves successfully to the OCSP auth agent and then directly it says the querying error. Could you please tell me if you see anything i could do to troubleshoot more ? Any ideas ? PS 1 : I tried also using the CA_2, a bundle of CA_1 and CA_2, a cert chain of both, but no luck ! PS 2 : when i use the CRLDP agent, i can see the status (revoked) in the APM logs. Thank you in advance !
Load balanced RDP VIP use in APM
HI I have a VIP on port 3389, load balancing to two rdp servers. RDP directly to that VIP IP works well. Now I created this as an rdp in apm, I used the dns name that the vip is resolving to as the destination address for the rdp, the apm url has a trusted cert. It gets as far as logging on then it throws the error: The connection has been terminated because an unexpected server authentication certificate was received from the remote computer Seems like the client connects to apm and gets the apm cert - trusted then they click the rdp icon and get the rdp file downloaded, the file has the gateway address of apm with trusted cert, and then the dns name of the rdp vip but then they get the servers real cert which doesn't match the vip dns name and errors. Can I proxy this connection on the F5? I have tried a combination of client and server profiles and the only way I get as far as a login prompt is to have no client or server profile in the vip. I would like the F5 to present its own apm cert to the client , I don't have the ability to put new SAN certs on the servers (not sure that would solve it anyway)
After upgrading from PeopleTools 8.59.11 to 8.61.11 F5 APM is not rewriting the internal URLs
After upgrading from PeopleTools 8.59.09 to 8.61.11 F5 APM is not rewriting all the internal urls for PeopleSoft Portal Application that also has Home page tiles from HRMS 9.2. Clicking on these tiles takes us to Internal URL instead of F5 externally resolvable url. How to troubleshoot this. I have a case opened with F5 support, but interested in any one else using F5 APM for peoplesoft and seeing similar error.APM VPN LDAP POOL can't contact ldap server.
Hi, I have a question regarding APM VPN and LDAP authentication. When I configure the LDAP server using the direct LDAP Server IP, the authentication works fine. However, when I use a Pool with the same LDAP Server IP, it shows the error message: "Can't contact LDAP server." From the packet capture, it seems that no traffic is being sent out at all. Is there any specific configuration I need to adjust for LDAP Pool settings? Thank you.
