Need help passing the cert to the pool member when using client/server ssl profiles

Question

Our application developers are launching Mirth and I've setup a Standard VIP listening on 443, http profile, with client/server ssl profile and an iRule (uri based). The server cert portion is working just fine, but was informed yesterday that they needed the client cert to be passed along to the pool members. After doing some reading, I set both profiles to Proxy SSL. Once I set that, they immediately saw SSL handshake failures. From a SSLDUMP I am seeing the following:

# ssldump -r /var/tmp/proxycap.pcap

New TCP connection #1: 10.144.22.176(53294) <-> 10.144.20.176(443)

The F5 is a 1600 running 12.1.2 code. let me know if I am overlooking something or there is a better way to perform this for the app team. Thanks.

&nbsp;&nbsp;As it appears that the pool member requires information from the client-side client auth certificate, you really need to use:   K72668381:&nbsp;&nbsp;Overview of the SSL Client Certificate Constrained Delegation feature&nbsp;which requires upgrading to 13.1.x&nbsp;  K14065425:&nbsp;&nbsp;Configuring Client Certificate Constrained Delegation (C3D)&nbsp;&nbsp;

Silly question, what is the latest version of software the 1600 series will support? Thanks again for your quick response!

Alright, back again. We had a 4200 unit lying around which was recently reclaimed from another location. I've wiped it clean and upgraded the software to BIG-IP 15.1.0 Build 0.0.31 Final. I've duplicated the VIP setup from lat time and appending in the C3D pieces to the client/server ssl profiles.

You probably need to capture both the client and server-side handshakes at the same time.

You may be getting a server-side authentication failure when the forged certificate is passed to the pool member.
