Description

Scenario:

- pfSense 2.4.4 AWS image with around 100 - 150 OpenVPN clients functions normally.

- After moving to 22.01 or 22.05 (be it an upgrade or re-deploy of the virtual machine), VPN clients experience traffic delays due to packet loss. This only seems to become noticeable when there are more than 10 VPN clients connected. The packet capture in the ticket was taken with about 95 clients connected, and it shows TCP retransmissions and duplicate acknowledgments between both the client filtered for (the 172.x.x.x address), and the domain controllers (the 10.x.x.x addresses), also on AWS. The loss is not constant, so there are sections of the capture which show no problems.

- Multiple upgrades and new deployments have been performed with the same result.

- Both importing the configuration and reconfiguring a fresh deployment has the same result.

- DCO is disabled.
