[Bug] stuck on infer network start!!!

Issue: Stuck on "infer network start" when running sample firmware in check mode

Hi, I'm encountering an issue when trying to run a sample firmware in check mode. The execution gets stuck at:
infer network start...

Environment:

OS: Ubuntu 18.04

Python: 3.10.8

What I’ve Checked:

I have reviewed the following logs:

makeNetwork.log

qemu.initial.serial.log

qemu.final.serial.log

From what I can tell, qemu-system seems to start successfully. However, the logs show the following messages:

'''
iptables v1.4.7: can't initialize iptables table 'nat': Table does not exist (do you need to insmod?)
wlt1: WLC_GET_VAR(authe_sta_list): No such device
wifig0: WLC_GET_VAR(chanspec): No such device
net interface not found
firmadyne: sys_socket [...] updatewifistats
'''

Is there anything I'm missing in terms of kernel modules (e.g., iptable_nat) or configuration that I should install to support NAT or networking in this emulation?

By the way, I’m running this in a Docker environment; here is the command I used:

docker run --privileged --net=host -it ubuntu:18.04 /bin/bash
