I am desperate at this point. I have been trying to configure a bridge networking on Ubuntu 17.10 and it has been hell. I can’t find any documents online to assist with install. All of the ones I have found are written for 16.04 and below. Can someone please help me. With this Net plan implementation instead of interfaces everything seems to be a headache. Below are my configurations.

I followed the steps from this page on the Ubuntu help wiki but the Prepare interface config for bridging on server step doesn’t seem to work since interfaces isn't there any more. Not sure how to bring
tap0 up/down. I seem to be having a routing issue when the clients connect.

Also I added the firewall rules
iptables -A INPUT -i tap0 -j ACCEPT iptables -A INPUT -i br0 -j ACCEPT iptables -A FORWARD -i br0 -j ACCEPT
What am I doing wrong?
