WireGuard VPN FW Rule Not Working as Intended

[curioustech]

I followed the instruction as per documentation.
https://wiki.opnsense.org/manual/how-tos/wireguard-client.html

Progress: Using Peer iPad, I am able to connect to WireGuard VPN successfully. (See iPad.log attached)
Issue: To route all the traffic using WireGuard VPN Tunnel only, I configured  0.0.0.0/0 in Allowed IPs. With that I see all the traffic coming to my OPNSense router. However, it's not going out. (See FW_Rule.png and FW_View.png attached)

I think that I have followed instructions correctly as documented in Step 2c - Assignments and Routing.

However, firewall live view suggests that traffic from the client is blocked.

Can someone please guide me on how to correct the firewall rule to allow internal and external access for WireGuard VPN users?
