Chelsio T520-CR NAT Offload (not the SO-CR)
-
I was wondering if anyone's looked into the T520-CR's NAT offload capabilities that are mentioned in the product brief linked below.

There is also a significant jump in the "Concurr. Conn" between the CR and the SO-CR when looking through the product selection page and I'm not sure if it's related to the NAT offload capability.

Wondering if pfSense or the upcoming TNSR release supports these features and what the limitations around them might be. I'm looking to build a big NAT (LSNAT - NAT44) capable of managing nearly 4 million sessions.
