What Certificates should be where? GSLB Trust Certificates vs Device Trusted Certificates
Hi All, My setup consists of two DC's with Two GTM's (Active/Standby) and Two LTM's (Active/Standby) in each DC. Within the GSLB Trusted Certificate Store, there are certs for each others devices, which I believe is the correct setup. (Each device has 8 certs, of its other devices)… However I am not sure about what should be in the "System - Certificate Management - Device Certificate Management - Device Trust Certificates store. (This is a bit of a mess, some devices have each others, some don't etc. Would like to have this cleaned up. For ease of description will refer to items as the following : - DC1GTMA - DC1 Active GTM DC1GTMS - DC1 Standby GTM DC1LTMA - DC1 Active LTM DC1LTMS - DC1 Standby LTM DC2GTMA - DC2 Active GTM DC2GTMS - DC2 Standby GTM DC2LTMA - DC2 Active LTM DC2LTMS - DC2 Standby LTM The four GTM's are in a device sync group "DNS - Settings - GSLB - General"...so when you make a change on one GTM, its replicated across all of them. Would this come under IQUERY and thus come under the GSLB Trusted Certificate store, or is this under the Device Trust Store? Hope the above makes sense. Thanks
Automating ACMEv2 Certificate Management on BIG-IP
While we often associate and confuse Let's Encrypt with ACMEv2, the former is ultimately a consumer of the latter. The "Automated Certificate Management Environment" (ACME) protocol describes a system for automating the renewal of PKI certificates. The ACME protocol can be used with public services like Let's Encrypt, but also with internal certificate management services. In this article we explore the more generic support of ACME (version 2) on the F5 BIG-IP.
Question on configuring SNI clientSSL Profile
Hi Experts , I have a question on configuring the SNI SSL profile .Suppose say I have 3 different certificate and 3 SSL profile to be attached to the VIP to configure SNI . https://www.securesite1.com ClientSSL1 > Default SSL Profile for SNI https://www.securesite2.com ClientSSL2 https://www.securesite3.com ClientSSL3 To enable SNI, we configure the Server Name and Default SSL Profile for SNI will be checked on an SSL profile of ClientSSL1, and then assign the profile to a virtual server. How about on other 2 SSL profiles ClientSSL2 & ClientSSL3 ? For other SSL profiles do I need to type the name for the HTTPS site in the Server Name box ? or it can be left blank ?
Certificate expiry monitoring
Hello Everyone! Would like to ask how you monitor your certs in your F5s? we would like to monitor the certificate expiry on our F5. I am checking our logs on ltm but it seems that the normal certs are not being logged. I only see cert bundles. Can you share how you monitor the certs expiry on f5?serverssl cipher suites
Hi, Is there an easier way to know what are the cipher suites that the backend server (pool member) can support? I have read an article but it requires to create a script. I know there is openssl but this will only show the cipher that the backend server used to communicate back with F5. So I was thinking like if from F5 perspective will it be able to perform an sslscan what are the available ciphers suites the backend server can support? Thanks, and regards, Rechie
Missing Certificate after redirect
We have a requirement for any calls coming into https://abc.com to be redirected to Azure APIM https://apim-xyz.com/api A simple following rule has been setup in F5 for calls coming into https://abc.com when HTTP_REQUEST { HTTP::respond 307 Location "https://apim-xyz.com/api" } But the problem we are facing is with client certificate. After the redirect, the client certificate is no longer available and new URL "https://apim-xyz.com/api" is not able to validate the request. We have no control over the client. We can control F5, redirect and server. Any help would be greatly appreciated.
