To enable, put the following in /etc/sysctl.conf for Ubuntu 17.04 deployments

net.core.default_qdisc=fq_codel net.ipv4.tcp_congestion_control=bbr

What for? What is it supposed to accelerate regarding the IPsec VPN? It doesn't use TCP.

This would be from the VPN server out to the internet.

It's still pretty much irrelevant for the VPN, because there's no proxy. Adding this sysctl setting would pretty much only ever pertain package updates and scp.
