Uzaktan erişim için (Android yol savaşçısı) Ubuntu 13.04'teki l2tp ipsec vpn'yi açar. Çalışmıyor

Buradan talimatları takip ettim: http://samsclass.info/ipv6/proj/proj-L5-VPN-Server.html

Bu sitede yayınlanan aynı dosyaları kullandım. Yönlendiricimde, bağlantı noktasını Ubuntu kutusuna 500 UDP ve 4500 UDP yönlendirdim. Android'de, denediğimde, "Bağlantı ..." ve ardından "Zaman Aşımı" seçeneğine gidiyor. Ayrıca iOS'ta (iPad) test edilmiştir ve çalışmaz. Her bağlantı denemesi için syslog'un xl2tpd'den hiçbir özelliği olmadığını fark ettim, bu nedenle openswan ipsec'in trafiği xl2tpd'ye geçirmediğini tahmin ediyorum?

Kılavuzdaki tüm adımlar tamamlandı:

added local ip address 172.22.1.1 eth0:0 (the Ubuntu box has eth0 192.168.0.50)
installed openswan
edited ipsec.conf, ipsec.secrets
stopped redirects
ipsec verify
restarted openswan
installed xl2tpd
edited xl2tpd.conf
ppp was already installed, so skipped this step
edited options.xl2tpd and chaps-secrets
restarted xl2tpd

[İpsec.conf]

# diff ipsec.conf ipsec.conf.template
21c21
<     left=192.168.0.50
---
>     left=YOUR.SERVER.IP.ADDRESS

.50 IP adresi, LAN'ımdaki Ubuntu sunucusunun eth0 IP adresidir.

[İpsec.secrets]

# cat /etc/ipsec.secrets
192.168.0.50   %any:  PSK "YourSharedSecret"

[xl2tpd.conf / options.xl2tpd / chap-sırları]
