L2TP over openswan<BR></FONT><BR></DIV>

<DIV><SPAN class=467433223-30112009><FONT face=Arial size=2>Is it possible to
set up l2tp/ipsec connection using openswan and xl2tpd and make the box working
as a layer 2 bridge?</FONT></SPAN></DIV>

<DIV><SPAN class=467433223-30112009><FONT face=Arial size=2>This is the
basic setup.</FONT></SPAN></DIV>

<DIV><SPAN class=467433223-30112009><FONT face=Arial size=2>LAN server 1
(192.168.0.100) <---> [192.168.0.1 VPN

<DIV><SPAN class=467433223-30112009><FONT face=Arial size=2>With l2tpd and pppd
running on the VPN gateway, the VPN client is able to create a ppp connection
(192.168.254.100 <--> 192.168.254.200) to the VPN gateway and ping
the LAN server 1. However, the broadcast packets sent by the LAN server can not
be seen by the VPN client working on a different subnet 192.168.254.x. Is there
any known solution?</FONT></SPAN></DIV>

<DIV><SPAN class=467433223-30112009><FONT face=Arial size=2>Ideally, I hope
l2tpd could give us a layer 2 tunnel interface so that we can add it to the LAN
side bridge interface. But it looks xl2tdp does not create such an interface and
it seems unavailable in the conf manual. </FONT></SPAN></DIV>

<DIV><SPAN class=467433223-30112009><FONT face=Arial size=2>If l2tpd can not
provide a layer 2 interface, can we use klips's tunnel interface? It seems to be
a layer 3 interface too, right?</FONT></SPAN></DIV>
