EdgeOS 1.9.1 l2tp ipsec vpn

So upgrading to the latest firmware on my Ubiquiti Edgerouter in typical fashion broke something I depend on, remote access to my home network.

The solution below was found in the forums. The poor fellow posted his problems September 9, 2016. Engineers responded January 27, 2017.

delete vpn l2tp remote-access outside-address
delete vpn l2tp remote-access outside-nexthop
set vpn l2tp remote-access dhcp-interface eth0

The official documentation states the outside-nexthop and outside-address were deprecated.
