I am a noob, so I guess I am doing something wrong.
Seems like a common issue but several hours of testing/reading forum inputs led to no resolution.
Setup/goal is:
All machines running as VirtualBox VM. I want to run OpnSense as a router firewall with WAN access and LAN to a Linux. Eventually I will run multiple VM on an internal network separated by the firewall/router.
Linux machine is running an internal network and its traffic must go through the firewall/router.
Machine 1:
OpnSense 19.1.4
Interface 1: eth0 using static IP 192.168.1.1/24 LAN (VirtualBox adapter set to Internal network)
Interface 2: eth1 using DHCP 10.0.3.15/24 WAN (VirtualBox adapter set to NAT)
Machine 2:
Interface: eth0 using Static IP 192.168.1.100 LAN (VirtualBox adapter set to Internal network)
Problem:
Following default and many forum comments. I should just install and basic rules are supposed to allow traffic from machine 2 to the Internet (on the WAN)
Tests:
Machine 1 can ping both Machine 1 and resources on the web.
Machine 2 can ping Machine 1 and connect to opnsense web Gui on Machine 1.
Machine 2 CANNOT access anything further than Machine 1.
Rules in place:
Only the default install rules
No VLAN, no bridge, no VPN

1. Your Machine 2 needs to have the default gateway set to your OPNsense LAN interface (192.168.1.1)
2. Your Machine 2 must be able to reach a DNS Server (your ISP or a public one like 1.1.1.1)
Usually (default installation) there shold be a DHCP service on the LAN interface allready running and provide your clients with IP addresses, default gateway and DNS server settings.

Thanks GOCE.
I had a typo on my default gw.
Once corrected all is working as I wanted.
