Здравейте,

Имам следната дилема :

Трябва да пусна ВПН с L2TP + IPSEC, но съм с ros 5.2 и туторияли никакви няма из нета. Всичко което е изписано съм пробвал, но без успех.

Моля някой ако е пускал да даде стъпка по стъпка как стават нещата.

Благодаря :)

Еми примерно - win7, iphone.... такива обикновени джаджи.

ето ти моя конфиг ;)

99.99... е примерно адреса на клиента

работи и с win7 и с vista


[admin@VPN] > interface l2tp-server server print 

          enabled: yes

          max-mtu: 1460

          max-mru: 1460

             mrru: disabled

   authentication: mschap2

  default-profile: default-encryption

[admin@VPN] > ip ipsec proposal print            

Flags: X - disabled 

 0   name="default" auth-algorithms=sha1 enc-algorithms=aes-128 lifetime=30m pfs-group=modp1024 

[admin@VPN] > ip ipsec peer print

При такава конфигурация ми дава следната грешка в дебъг режим :

11:28:14 ipsec,debug couldn't find configuration.

А ето и конфигурацията :

> /interface l2tp-server server print

enabled: yes

max-mtu: 1460

max-mru: 1460

mrru: disabled

authentication: mschap2

default-profile: default-encryption

> /ip ipsec proposal print

Flags: X - disabled

0 name="proposal1" auth-algorithms=sha1 enc-algorithms=aes-128 lifetime=30m pfs-group=modp1024

> /ip ipsec peer print

0 address=192.168.0.5/32 port=500 auth-method=pre-shared-key secret="test" generate-policy=yes exchange-mode=main

send-initial-contact=no nat-traversal=yes my-id-user-fqdn="" proposal-check=obey hash-algorithm=sha1

enc-algorithm=3des dh-group=modp1024 lifetime=1d lifebytes=0 dpd-interval=disable-dpd dpd-maximum-failures=1

Трябва още нещо да се конфигурира, но какво е ?

от 192.168.0.5 ли се пробваш да се вържеш?

може да сложиш на peer-а address=0.0.0.0 и да пробваш

това в proposal незнам дали има толкова значение , не съм спец по IPSEC :)
