lingering issues with FreeBSD 11 -> 12

I was unable to fully recover my FreeBSD 11 system so I started over w
FreeBSD 12. Couple of teething troubles still linger.

1 networking, specifically routing, seems to be off. I can't reliably
access sites to fetch/install ports and pkgs.

fetch:
https://files.pythonhosted.org/packages/source/a/acme/acme-1.29.0.tar.gz:
Network is unreachable

ping files.pythonhosted.org

PING dualstack.r.ssl.global.fastly.net (151.101.21.63): 56 data bytes

ping: sendto: No route to host

from /etc/rc,.conf

defaultrouter=192.168.0.1

ifconfig_em0=192.168.0.25

ifconfig_em0_ipv6="inet6 accept_rtadv"

ipv6_ifconfig_em0="2001:470:b:839:a00:27ff:fe5c:8bcb"

ipv6_default_router=2001:470:0:3d::1

This has worked but isn't working now. I can ssh into the system w/in my
local network just fine.

2 Python flavors?

/!\ WARNING /!\


PYTHON_DEFAULT must be a version present in PYTHON2_DEFAULT or
PYTHON3_DEFAULT,

if you want more Python flavors, set BUILD_ALL_PYTHON_FLAVORS in your
make.conf

A look through UPDATING didn't enlighten me as to what I need to do here.
This is now such a small part of my daily life, what I want is whatever I
need to copy/paste in /etc/make/conf.
