Qemu network cant connect guest to LAN or internet

My test setup before moving it to my actual server is as follows:
Laptop with eth and wlan > eth0 on green (has full LAN access) and wlan0 on red (connected to my AP and has internet)
qemu setup with vnc and connection to guest OS is working

I have followed the wiki to setup qemu to start my guest and create the orange network but the device name under setup for orange is "???: Unknown Network Interface (orange0)’

Under /var/ipfire/settings:
ORANGE _DRIVER=‘Unknown Network Interface (orange0)’
ORANGE_DEV=orange0 and ORANGE_DESCRIPTION="???: Unknown Network Interface (orange0)’

I have used setup to configure an IP for orange (192.168.2.252) and am able to ping this IP from LAN but am not able to ping guest IP (192.168.2.253) from any device or my ipfire host.

Can anyone shed some light as to where I am going wrong? I have tried setting green to bridge but end up with only local access to ipfire machine (no ping from LAN either).I know that orange needs to be a virtual device but am stumped as to the correct setup and configuration method.

thanks
