Logging Server-IP with OneConnect

Due to the usage of SNAT (design requirement) the servers are loosing the visibility, which real clients are connecting. Therefor the LTM should provide these information with internal logging (client-IP <-> VS <-> server-IP).
But we are also using OneConnect, where logging of all sub-sequent requests of an existing server-side connection are getting "lost".
Is there any solution available to still provide such a full logging information with OneConnect enabled?
Or is disabling OneConnect the only solution?
Thank you!
