Hi all, some news about my problem about Ipsec\L2tpd connection.First of all I realized my router filter all the ping-tries, and so that's the reason it fail.Then I established the L2tpd connection from my roadwarrior to the server, assigning to the client an IP address of the gateway's LAN, and 
everything work.I mean, if i ping the virtual address of the warrior inside the lan from an host within the lan, my roadwarrior reply to the requests.Now, the real problem: I'm still not able to establish the L2tp connection OVER the IPsec tunnel.I mean: I can establish the host-to-host IPsec tunnel easily (this is what /etc/init.d/ipsec status told me), but after this 
I'm not able to establish the L2tpd connection.
Whe I lunch the xl2tpd daemon on my roadwarrior, I can only see ESP packets to the server without any reply from this last one, and plus 
no packets reach the server. It looks like the packets are not able to reach the server, and so they go missed.I tryed Linux and WinXP client, following Jacco's pages, but with no luck.The labs where I'm testing this thesis work is equipped with a block of public IP addresses, which is, and are
the 3 free IP addressess of the LAN, a.b.c.51 and a.b.c.52 will be assigned to my roadwarriors.
Here are my conf files
