# This is a humble fork modification to the master work from EvilFreelancer
|
|
# These entrypoint is for maximum 8 interfaces using Docker virtual networks
|
|
# (need 8 custom bridge networks in docker)
|
|
# First qemubr1 use DHCP as EvilFreelancer did
|
|
# next 7 interfaces qemu neeed you set 7 fixed ip address in winbox
|
|
# you must create before 8 networks in your docker and attach to the container
|
|
# Also I have enabled 4 cores in the qemu vm
|
|
# Only for testing purpose or use in lab, please dont use in production
|
|
# this router has a free license - 1Mbps only
|
|
# I have tested and it is working great anyway
|
|
# It needs some help with the DRY if you have the time please fork
|
|
# regards # lcchatter #

# And run the VM! A brief explanation of the options here:
|
|
# -enable-kvm: Use KVM for this VM (much faster for our case).
|
|
# -nographic: disable SDL graphics.
|
|
# -serial mon:stdio: use "monitored stdio" as our serial output.
|
|
# -nic: Use a TAP interface with our custom up/down scripts.
|
|
# -drive: The VM image we're booting.
|
|
# mac: Set up your own interfaces mac addresses here, cause from winbox you can not change these later.
