VPN：Cisco / Watchguard：IKE 與遠端對等點失去聯繫

我正在嘗試在 Cisco ASA 5510（7.0(5) 固件，IP 222.222.222.222）和 Watchguard X750e 防火牆（10.2 固件，IP 111.111.111.111）之間設定 LAN 到 LAN VPN

階段 1 出現，但隨後日誌中出現訊息“IKE 與遠端對等點失去聯繫，刪除連線”，並且 ASa 從未啟動第 2 階段設定。可能是什麼原因造成的？

日誌和配置資訊如下，對於看起來醜陋的文字牆感到抱歉：

從ASA端的日誌來看：

在 Watchguard 端：

11:08:36 iked Drop negotiation to peer 222.222.222.222:500 due to phase 1 retry timeout msg_id="0203-5161"             Debug

我們最後的配置如下所示：

object-group network REMOTENETWORK
 network-object 215.12.34.0 255.255.255.0

access-list outside_cryptomap_100 extended permit ip 10.88.88.96 255.255.255.240 object-group REMOTENETWORK 
access-list outside_cryptomap_100 extended permit ip 10.88.88.128 255.255.255.224 object-group REMOTENETWORK 

crypto ipsec transform-set ESP-3DES-SHA esp-3des esp-sha-hmac 

crypto map outside_map 100 match address outside_cryptomap_100
crypto map outside_map 100 set peer 111.111.111.111 
crypto map outside_map 100 set transform-set ESP-3DES-SHA

tunnel-group 111.111.111.111 type ipsec-l2l

答案1

以下是有關 IKE SA 不匹配的一些提示的鏈接，可能會有所幫助（還有一些要查看的調試命令）：

答案2

您嘗試過停用 DPD 嗎？不同供應商之間的 DPD 可能會正常運作... 兩個設備是否都設定為使用主模式？一遍又一遍地檢查設定..

答案3

您必須在第一階段為網關 ip 提供 DNS 名稱或 IP 位址。

輸入IP位址並在其下方的下拉方塊中選擇IP。
