Default Strange OpenVPN problem - started recently

I recently upgraded from OpenBSD 6.1 to 6.3. In the process, OpenVPN was upgraded from version 2.4.1 to 2.4.5. Despite an identical configuration that was previously working, I no longer have Internet access through my VPN.

This is a "road warrior" type setup, with my router doubling as my OpenVPN gateway. I am able to access my internal network remotely via the VPN, and firewall monitoring indicates traffic for the Internet is being sent out the WAN port and forwarded on. But for some reason, return traffic from the Internet is no longer being routed/sent back through the VPN to my client box. Routes on both the client box and the router look as they did before.

I'm really at a loss where to go next with this. The behavior explicitly started after I upgraded the OpenVPN package (and not after upgrading from OBSD 6.1 to 6.3). Has anyone else seen this behavior? Did something change in configuration for OpenVPN recently that might account for this?
