PIX到PIX 6.x:Easy VPN(NEM)配置示例

簡介

本文檔提供了PIX Easy VPN遠端硬體客戶端和PIX Easy VPN伺服器之間的IPsec配置示例。PIX的Easy VPN Remote功能是在PIX版本6.2中引入的，也稱為硬體客戶端/EzVPN客戶端。PIX軟體6.0版及更高版本支援Cisco Easy VPN伺服器。

請參閱將ASA 5500作為伺服器並將PIX 506E作為客戶端(NEM)的PIX/ASA 7.x Easy VPN配置示例，以瞭解更多有關安全裝置使用軟體版本7.x運行的相同方案的資訊。

請參閱PIX/ASA 7.x Easy VPN(將ASA 5500作為伺服器，將Cisco 871作為Easy VPN Remote配置示例，瞭解有關將Cisco 871路由器作為Easy VPN Remote的類似方案的詳細資訊。

請參閱PIX 501/506系列安全裝置上的VPN硬體客戶端和VPN 3000集中器配置示例，以瞭解有關Cisco VPN 3000集中器充當Easy VPN伺服器的類似方案的詳細資訊。

請參閱PIX 501/506 Easy VPN Remote to an IOS Router in Network Extension Mode with Extended Authentication配置示例，以瞭解有關Cisco IOS®路由器充當Easy VPN伺服器的類似方案的詳細資訊。

疑難排解

本節提供的資訊可用於對組態進行疑難排解。

如果已按本文檔所述設定Easy VPN Remote Hardware Client和Easy VPN Server且仍然遇到問題，請收集每個PIX的debug輸出和show命令的輸出，以供Cisco技術支援中心(TAC)進行分析。 另請參閱排除PIX故障以在已建立的IPsec隧道上傳遞資料流量或IP安全性故障排除 — 瞭解和使用debug命令。在PIX上啟用IPsec調試。

此處顯示PIX debug命令和輸出示例。

• Easy VPN伺服器命令

• Easy VPN遠端硬體客戶端命令

附註：使用 debug 指令之前，請先參閱有關 Debug 指令的重要資訊。

Easy VPN伺服器命令

• debug crypto ipsec — 顯示第2階段的IPsec協商。

• debug crypto isakmp — 顯示第1階段的ISAKMP協商。
