Добрый день, Уважаемые!
Возникла проблема при создания туннеля IPSEC между двумя офисами в разных городах, в сети "А" в роли шлюза выступает машина с CENTOS, в сети "Б" шлюз Dlink DL804HV, коннект не устанавливается.
Как настраивал
Сеть "А"
Центось настраивал по документации
http://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-ipsec-net2net-cfg.html
Создал скрипт
Код:
/etc/sysconfig/network-scripts/ifcfg-ipsec0
TYPE=IPSEC
ONBOOT=yes
IKE_METHOD=PSK
SRCGW=192.168.1.3
DSTGW=192.168.4.100
SRCNET=192.168.1.0/24
DSTNET=192.168.4.0/24
DST=Внешний_IP_Сети"В"
Создал ключ
Код:
/etc/sysconfig/network-scripts/keys-ipsec0
подредактировал /etc/racoon/racoon.conf
Код:
cat /etc/racoon/racoon.conf
# Racoon IKE daemon configuration file.
# See 'man racoon.conf' for a description of the format and entries.
path include "/etc/racoon";
path pre_shared_key "/etc/racoon/psk.txt";
path certificate "/etc/racoon/certs";
listen
{
isakmp Внешний IP Сети "А";
}
timer
{
# These value can be changed per remote node.
counter 5; # maximum trying count to send.
interval 10 sec; # maximum interval to resend.
persend 1; # the number of packets per send.
# maximum time to wait for completing each phase.
phase1 30 sec;
phase2 15 sec;
}
sainfo anonymous
{
pfs_group 2;
lifetime time 1 hour ;
encryption_algorithm 3des ;
authentication_algorithm hmac_md5 ;
compression_algorithm deflate ;
}
в iptables добавил правила
Код:
-A INPUT -p udp --dport 500 -j ACCEPT
-A INPUT -p esp -j ACCEPT
-A INPUT -p ah -j ACCEPT
Сеть "Б" Настройки длинка
