Cannot access internet from LAN

Hi, this is a new setup running on a VM (Xenserver) with 2 NICs.
I have setup one for WAN, one for LAN. From my LAN, I'm unable to access internet (ping 8.8.8.8 fails).
I have same setup running a fresh install of pfsense, have similar problem. I needed to add a firewall LAN rule to LAN net to access to get it working on pfsense.

I see OPNSense have setup that rule automatically (nice), but the firewall logs shows it passes (e.g. 10.0.0X)

It looks like your XEN is behind another firewall? If so, in Interfaces/WAN make sure "Block private networks" isn't enabled.

It's behind another router. Nope "Block private network" is unchecked.
The same setup works with pfsense VM fine, and both are fresh setup. I configured the same way as pfsense.

I need to manully add NAT outbound rule to any to get it to work. The auto generated rule does not allow it.

I am new to Opnsense(PFSENSE user for many years) and am running OPNsense-18.1.6-OpenSSL-vga-amd64.img.bz2. From what I can tell all is setup correctly but my lan is not able to access the Internet. Following is what I have done:
1) From the Interface diags I can ping an address on the Internet.
2) From my lan workstation I can resolve a DNS name but I cannot ping, nor bring up a webpage.
3) Ran a packet capture on the Lan and see the attempt. Ran a capture on the WAN, filtering on the Internet destination address, and I see no packets.
I'm thinking this means my private addresses are not being natted? How else can I isolate why this is happening?
Thank you.
