Здравствуйте!

   У меня такая проблема. Есть Allied Telesyn AR770S и Cisco ASA 5550. Между ними необходимо построить VPN.
   VPN между ASA5550 и Cisco851 с аналогичными настройками работает замечательно, а вот между ASA5550 и AR770S ни в какую. Пожалуйста, помогите разобраться.

   Конфиг ASA 5550:
access-list VLAN604_cryptomap_1 extended permit ip zzz.zzz.0.0 255.255.0.0 yyy.yyy.16.0 255.255.252.0

crypto map VLAN604_map 1 match address VLAN604_cryptomap_1
crypto map VLAN604_map 1 set peer xxx.xxx.xxx.9
crypto map VLAN604_map 1 set transform-set ESP-DES-MD5
crypto map VLAN604_map 1 set security-association lifetime seconds 600
crypto map VLAN604_map 1 set nat-t-disable
crypto map VLAN604_map interface VLAN604

crypto isakmp identity key-id 12
crypto isakmp enable VLAN604

crypto isakmp policy 5

encryption des
hash md5
group 1
lifetime 600
no crypto isakmp nat-traversal

   Конфиг AR770S:

• Не поднмается VPN между Cisco ASA 5550 и Allied Telesyn AR77...,jeka64, 12:56 , 24-Июн-09
  • Не поднмается VPN между Cisco ASA 5550 и Allied Telesyn AR77...,jeka64, 09:25 , 25-Июн-09

Сейчас настроил VPN между Cisco 2811 и Allied Telesyn. Все работает. Где же ошибка в конфиге Cisco ASA?

Судя по логам они немогут пройти 1 фазу.

Почему aes-256? Ведь в конфиге прописано des.
