PROXMOX doesn't have internet connection but OPNSENSE does.

[redpudge]

apologize if posting on the wrong forum.
New in proxmox and networking but hope someone can help.
This is the setup that I've managed to built. internet->modem->Proxmox (opnsense) -> WirelessAP -> home devices
Within Proxmox I have virtualised OPNsense as router/dhcp/firewall.
Managed to setup everything successfully with a lot of trial and error but still cant fix the configuration.
To access the proxmox console I have to connect RJ45 directly to vmbr4


OPNSense console 192.168.1.1
Proxmox console 192.168.1.20
WAP 192.168.1.10

thanks in advance
