Hi all, <BR>some news about my problem about Ipsec\L2tpd connection.<BR>First of all I realized my router filter all the ping-tries, and so that's the reason it fail.<BR>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 <BR>
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.<BR>Now, the real problem: I'm still not able to establish the L2tp connection OVER the IPsec tunnel.<BR>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 <BR>
I'm not able to establish the L2tpd connection.<BR>
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 <BR>
no packets reach the server. It looks like the packets are not able to reach the server, and so they go missed.<BR>I tryed Linux and WinXP client, following Jacco's pages, but with no luck.<BR>The labs where I'm testing this thesis work is <BR>equipped with a block of public IP addresses, which is 141.250.40.0/24, and 141.250.40.51-141.250.40.52-141.250.40.56 are<BR>
the 3 free IP addressess of the LAN, a.b.c.51 and a.b.c.52 will be assigned to my roadwarriors.<BR>
