VPN doesn't go on a RFC1483 LLC routed, and goes on PPPoE

Archived from groups: comp.dcom.vpn (More info?)

I have three sites:
two has PPPoE connection, with DSL modem and variable IP
one has RFC1483 LLC routed, with DSL router and fixed IP

each one has IPCOP v1.4.5, and every machine is directly pingable; (the
router is configurated with DMZ to IPCOP machine)

The problem is that VPN goes on two PPPoE sites, and doesn't on the
other site.
Seeking the "ipsec barf" I can see this:
Apr 10 23:57:56 ipcop pluto[3071]: packet from xxx.xxx.xxx.xxx:500:
initial Main Mode message received on 192.168.1.1:500 but no connection
has been authorized with policy=PSK

(xxx.xxx.xxx.xxx is public IP of the "remote" machine)
(192.168.1.1 is the red IP of IPCOP)

The lan is so configurated:
router: wan: fixed ip
router: lan: 192.168.1.254
|
ipcop: red: 192.168.1.1
ipcop: green: 192.168.130.254
|
lan 192.168.130.0/255.255.255.0


The configuration are similar on the three IPCOP machine, so the only
different is on RFC1483 sites. But what?


Code:

left=xxx.xxx.xxx.xxx
leftnexthop=%defaultroute
leftsubnet=192.168.130.0/255.255.255.0
right=yyy.yyy.yyy.yyy
rightsubnet=192.168.101.0/255.255.255.0
rightnexthop=%defaultroute
dpddelay=30
dpdtimeout=120
dpdaction=hold
authby=secret
auto=start

    Reading about it
    (http://community.smoothwall.org/forum/viewtopic.php?t=6519), I have
    found only an error in my last configuration, but it doesn't solve
    anyway: leftid's param

    so, the connection should be:

    left=xxx.xxx.xxx.xxx (red ip of ipcop 192.168.1.1)
    leftnexthop=%defaultroute
    leftid=zzz.zzz.zzz.zzz (public ip of the router connected to internet)
    leftsubnet=192.168.130.0/255.255.255.0
    right=yyy.yyy.yyy.yyy (public ip of the remote)
    rightsubnet=192.168.101.0/255.255.255.0
    rightnexthop=%defaultroute
    dpddelay=30
    dpdtimeout=120
    dpdaction=hold
    authby=secret
    auto=start

    +++++++++++++
    but nothing, the results is the same:

    Apr 13 14:52:01 ipcop pluto[10322]: packet from yyy.yyy.yyy.yyy:500:
    initial Main Mode message received on 192.168.1.1:500 but no connection
    has been authorized with policy=PSK

    and it's the same for the other end's:
    Apr 13 14:54:13 ipcop pluto[15548]: packet from zzz.zzz.zzz.zzz:4500:
    initial Main Mode message received on yyy.yyy.yyy.yyy:4500 but no
    connection has been authorized with policy=PSK


    Seeking, route log of the dsl router show that there is connection from
    192.168.1.1 to yyy.yyy.yyy.yyy

    What can I do to solve?

    I have found a new issue. Thinking, there is a problem with
    ipsec.secrets....

    the message on "ipsec barf" say that is missing something... so I have
    tried to insert more "secrets"... like:
    192.168.1.1 yyy.yyy.yyy.yyy
    and some other...

    results: the connection now became opened, even if routing doesn't
    work...

    in case of a router, how is the right ipsec.secrets pam's?

    I sovle an "old" problem about making up a VPN with two IPCOP machines,
    where in one DSL is a PPPoE type, and another one is IPoA type.

    The router used on IPoA must permit VPN-passthrough

    Problems solves with a manual modify of files on IPCOP machines where
    is IPoA connection:
    /etc/ipsec.conf
    /etc/ipsec.secrets


    /etc/ipsec.secrets:
    this file must referring to RED IPCOP interfaces (192.168.1.1) and to
    WAN address (xxx.xxx.xxx.xxx is the public IP addresso of other side of
    VPN):
    
    192.168.1.1 xxx.xxx.xxx.xxx : PSK "password"
    WANIPpubblic xxx.xxx.xxx.xxx : PSK "password"
    


    /etc/ipsec.conf:
    follow this schema
    left= RED IP of IPCOP
    leftid= public WAN IP
    leftnexthop= IP address of gatway (router)

    
    conn NameConnection
            left=192.168.1.1
            leftid=WANIPpubblic
            leftnexthop=192.168.1.254
            leftsubnet=192.168.130.0/255.255.255.0
            right=xxx.xxx.xxx.xxx
            rightsubnet=192.168.100.0/255.255.255.0
            rightnexthop=%defaultroute
            dpddelay=30
            dpdtimeout=120
            dpdaction=hold
            authby=secret
            auto=start
