I'm trying to connect to a vpn service that uses L2TP without IPSEC.
I installed and configured xl2tpd, but I don't know how to make it work.
The log says the following:
xl2tpd[5263]: Connecting to host 64.55.144.10, port 1701
xl2tpd[5263]: Connection established to 64.55.144.10, 1701. Local: 37195, Remote: 18803 (ref=0/0).
