NETGEAR, 2nd NIC
Trying to emulate a NETGEAR XR500, have the physical device as well so was able to get the firmware and nvram settings all copied over in to a template easily.
Mostly it's working,

a lot of the services have started, however it looks like the device needs a 2nd NIC
RawEthLan=eth1
RawEthWan=eth0
ifconfig $RawEthLan hw ether $wandefmac
ifconfig $RawEthWan hw ether $wandefmac
ifconfig $BondEth hw ether $wandefmac
ifconfig $BondEth up
vconfig add $BondEth 1 && ifconfig $BondEth.1 down
vconfig add $BondEth 2 && ifconfig $BondEth.2 down
ip link set dev $BondEth.1 name ethlan
ip link set dev $BondEth.2 name ethwan
brctl addif br0 ethwan
Without it, br0 is never created and most network service like httpd are never started.
I think this is done by adding a new entry to qemuopts but can not figure it out.
Any advice?
I have been thinking of creating a second tap device for quite some time. It will require three things:
a) Adding another tap device in the container itself. This can be done via /etc/local.d/10-tun-network.start
b) Adding options to qemuopts, basically for both tap devices
c) Some network config in the hostfs as well
I'll ponder this.
I'll take you up on that! Meanwhile it does look quite similar to the Netgear R6700v3 that I recently emulated. And it works with br0 without a second ethernet:
# ifconfig

And httpd is running. Would you be so kind and DM/Email me please? saumil -at- saumil -dot- net
@kevthehermit Do you have more information on how you have emulated this device? Can I contact you?
