[Openswan Users] Problem connecting with a Linux client

[Adrian Chapela]

Hello,

I have configurated a Linux IPSEC/L2TP server. I can connect Ok with a
Windows 7 but I can't connect with a Linux client. When I use Linux I
can see the the tunnel and the ppp0 interface created OK, as you can see
below:

ppp0      Link encap:Point-to-Point Protocol 
          inet addr:10.10.10.1  P-t-P:10.10.10.2  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1400  Metric:1
          RX packets:246 errors:0 dropped:0 overruns:0 frame:0
          TX packets:24 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3
          RX bytes:19801 (19.3 KiB)  TX bytes:1832 (1.7 KiB)

But when I use the Linux client the result is the next:
ppp0      Link encap:Point-to-Point Protocol 
          inet addr:10.10.10.1  P-t-P:192.168.0.2  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1400  Metric:1
          RX packets:246 errors:0 dropped:0 overruns:0 frame:0
          TX packets:24 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3
          RX bytes:19801 (19.3 KiB)  TX bytes:1832 (1.7 KiB)

Why the Linux is not getting a correct IP ?

Client config:

[global]
ipsec saref = yes
port = 1701


[lac test]
lns = 192.168.0.1
require pap = yes
require authentication = yes
pppoptfile = /etc/ppp/options.l2tpd.client
length bit = yes
hostname = tomcat2
ppp debug = yes

Server config:
[global]
ipsec saref = yes
port = 1701
auth file = /etc/xl2tpd/l2tp-secrets
debug tunnel = yes
debug avp = yes
debug packet = yes
debug network = yes
debug state = yes


[lns default]
exclusive = no
ip range = 10.10.10.2 - 10.10.10.20
local ip = 10.10.10.1
assign ip = yes
require authentication = yes
require pap = yes
;require chap = yes
ppp debug = yes
pppoptfile = /etc/ppp/options.l2tpd

I don't know what is happening.

Thank you!
