rp-l2tp supports Road Warriors, and it can assign static IP addresses through
PPP with the use of chap-secrets. I have made (S)RPMs of rp-l2tp with sample
configuration files similar to those in l2tpd, see:

I have not used l2tpns myself but it seems you will need a RADIUS server
to assign the IP addresses. l2tpns has built-in PPP support but it does
not seem to be as extensive as pppd. For instance, I see no mention of
configuring WINS.
