pfsense OpenVPN Client with DCO no traffic passing

[Slothstronaut]

As the topic states, I have pfsense Plus (tested with both 22.05 and 23.01), with OpenVPN as a client connecting to a popular VPN provider. With DCO turned off, all is well. If I enable DCO, the tunnel connects and I get an IP, but no traffic flows. I can see that the interface is created and it gets an interface IP. But trying to ping across it gets zero output.

Nothing notable in the logs that is different than non-DCO mode, it will ping-timeout and restart the tunnel every 30 seconds or so.

I realize this is a beta feature and understand there will be hangups, any insight where I can begin troubleshooting? In my searches, all the results are for people using pfsense as the server side, so the config changes don't apply.

Thanks!
