First time build - no internet 23.1

[Soogs]

Hi all

I've been googling for hours and have had a good search here too but couldnt find anything thats helps.

Setup: Proxmox VM
cpu i7-4785t 4 cores allocated
ram 4gb allocated
ssd 8gb allocated
internal NIC
usb NIC

NICs
em0 - LAN 192.168.1.49/24 (attached to vmbr0)
em1 - WAN DHCP (attached to vmbr0)
em2 - OPT1 (LAN2) 192.168.64.1 DHCP server enabled (attached to vmbr1 / USB NIC)

Internet connection to OPNsense itself is working as I was able to update from 22.7 to 23.1

Issue: no internet connection on OPT1.

Things I've tried:
-cloning the LAN to any rule
-disabling the firewall altogether
-adding a floating rule allowing any internface inc wan to any interface
-allowing any interface to WAN/privnets and BOGON
-used different DNS

notes:
-DHCP is working as the travel router which is attached to OPT1 is picking up an address, however no internet access.
-vmbr1 does not have an any ip or gateway associcated in Proxmox (though I think this how it is meant to be?)
-WAN connection comes from my EdgerouterX which connects to two WANs (Failover).
-Both top level WANs are in bridge mode
-I have recycled the VM many times
-I have reset to default and started over many times

I can't get my head around what the issue is here?

Anyone else had this issue or similar?

Any help is appreciated.
TIA

What do your rules on OPT1 look like? What do your outbound NAT rules on WAN look like?

I've just started pver and cloned the LAN rule to OPT1

they are as below (sorry for the formatting)

OPT1
   Protocol    Source    Port    Destination    Port    Gateway    Schedule    Description    
            
      IPv4     *         *                *                      *                 *      *    *    Default allow OPT1 to any rule

Outbound WAN
Automatic outbound NAT rule generation
(no manual rules can be used)

Interface    Source Networks    Source Port    Destination    Destination Port    NAT Address    NAT Port    Static Port    Description
        WAN    LAN networks, Loopback networks, OPT1 networks, 127.0.0.0/8    *    *    500    WAN    *    YES    Auto created rule for ISAKMP
        WAN    LAN networks, Loopback networks, OPT1 networks, 127.0.0.0/8    *    *    *    WAN    *    NO    Auto created rule
