+# 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
