Доброго времени суток!
Имеются два роутера ASUS RT-N10U с прошивкой DD-WRT v24-sp2 (03/25/13) vpn.
Один сконфигурирован как сервер, другой - как клиент. Все делается в рамках учебного задания, поэтому все в пределах локальной сети.
IP сервера 192.168.2.1/24
IP клиента 192.168.2.2/24
VPN раздает IP из подсети 10.8.0.0/24

Настройки сервера:
OpenVPN Server/Daemon
OpenVPN: Enable
Start Type: WAN Up
Config as: Daemon
Additional Config:
Code:
push "route 192.168.2.0 255.255.255.0"
push "route 192.168.2.1 255.255.255.255"

server 10.8.0.0 255.255.255.0

dev tun0
proto tcp
keepalive 10 120
dh /tmp/openvpn/dh.pem
ca /tmp/openvpn/ca.crt
cert /tmp/openvpn/cert.pem
key /tmp/openvpn/key.pem

comp-lzo

management localhost 16</code>
Administration - Commands - Firewall:
<code>iptables -I INPUT 1 -p udp -dport 1194 -j ACCEPT
iptables -I FORWARD 1 -source 192.168.2.0/24 -j ACCEPT
iptables -I FORWARD -i br0 -o tun0 -j ACCEPT
iptables -I FORWARD -i tun0 -o br0 -j ACCEPT


Настройки клиента:


Конфигурация клиента имеет следующий вид:
Code:
client
dev tun
proto tcp
remote 192.168.2.1 1194
resolv-retry infinite
nobind
persist-key
persist-tun

ca /tmp/openvpncl/ca.crt
cert /tmp/openvpncl/client.crt
key /tmp/openvpncl/client.key
ns-cert-type server

comp-lzo
verb 4

При запуске клиента, он пропадает (ни по 192.168.2.2, ни по 10.8.0.6 подключиться нельзя
На клиенте успеваю наблюдать следующее в Status - OpenVPN:

Пробовал ставить на клиенте SHA1 и MD5
клиент с теми же сертификатами и такой же конфигурацией успешно получает IP и пингует роутер (10.8.0.1)[/img]
