Hey guys,
I am desparate 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 Netplan implementation instead of interfaces everything seems to be a headache. Below are my configurations.
Info:
router: 10.0.1.1
ip address 10.0.1.100
network 10.0.1.0
gateway 10.0.1.1
dns: 10.0.1.1
netmask 255.255.255.0
[admin@SKYNET:~$ cat /etc/netplan/01-netcfg.yaml

I followed the steps from https://help.ubuntu.com/lts/serverguide/openvpn.html.en but the “Prepare interface config for bridging on server” doesn’t seem to work since there isn’t anymore “interfaces”. Not sure how to bring tap0 up/down. I seem to be having a routing issue when the clients connect.
