Public bug reported:
I have install Ubuntu 17.10 64 bit server and set a static IP address as
well as an IPv6 address. I have also tried using DHCP6 as well. I can
ping locally any address on the same VLAN. I cannot ping outside of the
local addresses. This is a new install on a Dell R710 running ESXi. I
have other servers that have no problem routing, this is the only server
using netplan. I have tried adding a static route, setting gateway6: and
neither works.
netplan config:
