In addition to Nate's suggestions, the l2tpd.conf would have to start with
something like this:

[global]
; listen-addr = A.B.C.D

[lns default]
ip range = A.B.C.F.-A.B.C.K
local ip = A.B.C.L

I heartily recommend the listen-addr parameter for extra security. It does
require some extra iptables wizardry, however.
