If the tunnel is coming up, thant thats good. You need to :
1. have l2tp setup to listen on an internal interface on your remote network, and be setup
to use chap user/passwrd and hand out an IP address.
2. Add an iptables rule in the prerouting section simular to this :
Chain PREROUTING (policy ACCEPT 3555K packets, 244M bytes)
pkts bytes target prot opt in out source destination
27 3595 DNAT udp -- ipsec0 * 0.0.0.0/0 0.0.0.0/0 udp
spt:1701 dpt:1701 to:192.168.0.1
This way l2tp packets coming in on ipsec0 get prerouted over to the internal interface,
which is where the l2tpd should be listening.
