採用Windows 7或Android VPN客戶端和證書身份驗證配置的ASA IKEv2 RA VPN
目錄
簡介
本文檔介紹如何配置Cisco Adaptive Security Appliance(ASA)9.7.1版及更高版本，以便允許Windows 7和Android本地（虛擬專用網路）VPN客戶端使用網際網路金鑰交換協定(IKEv2)和證書作為身份驗證方法建立（遠端訪問）RA VPN連線。
作者：David Rivera和Cesar Lopez Zamarripa，思科TAC工程師。
必要條件
需求
思科建議您瞭解以下主題：
- 證書頒發機構(CA)
- 公開金鑰基礎架構 (PKI)
- ASA上帶IKEv2的RA VPN
- Windows 7內建VPN客戶端
- Android原生VPN客戶端
採用元件
本檔案中的資訊是根據以下軟體版本：
- CISCO1921/K9 - 15.5(3)M4a（作為IOS CA伺服器）
- ASA5506X - 9.7(1)作為VPN頭端
- Windows 7作為客戶端電腦
- Galaxy J5 - Android 6.0.1作為移動客戶端
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。
設定
概觀
以下是配置Windows 7和Android本地VPN客戶端以連線到ASA頭端的步驟：
配置證書頒發機構
CA允許將所需的擴充金鑰使用(EKU)嵌入憑證中。對於ASA頭端，需要證書伺服器身份驗證EKU，而客戶端證書需要客戶端身份驗證EKU。
可以使用各種CA伺服器，例如：
- Cisco IOS CA伺服器
- OpenSSL CA伺服器
- Microsoft CA伺服器
- 3rd 參與方CA
此配置示例使用IOS CA伺服器。
本節概述使版本15.5(3)M4a的CISCO1921/K9作為CA伺服器工作的基本配置。
步驟1.確保裝置和版本支援eku命令。
IOS-CA# show run | section crypto pki crypto pki server <CA_Server> issuer-name <cn=calo_root,ou=TAC,o=cisco> grant auto eku server-auth client-auth
步驟2.在路由器上啟用HTTP伺服器。
IOS-CA(config)#ip http server
步驟3.生成可匯出的RSA金鑰對。
IOS-CA(config)# crypto key generate rsa modulus 2048 label <HeadEnd> exportable The name for the keys will be: HeadEnd % The key modulus size is 2048 bits % Generating 2048 bit RSA keys, keys will be exportable... [OK] (elapsed time was 5 seconds)
步驟4.配置信任點。
IOS-CA(config)# crypto pki trustpoint <HeadEnd> IOS-CA(ca-trustpoint)#enrollment url http://10.201.180.230:80 IOS-CA(ca-trustpoint)#subject-name <cn=HeadEnd.david.com> IOS-CA(ca-trustpoint)#revocation-check none IOS-CA(ca-trustpoint)#rsakeypair <HeadEnd>
步驟5.驗證信任點（取得CA憑證）。
IOS-CA(config)#crypto pki authenticate <HeadEnd>
Certificate has the following attributes:
Fingerprint MD5: DA4502F4 CEFB4F08 AAA3179B 70019185
Fingerprint SHA1: A887F6DB 0656C7E2 857749F3 EA3D7176 8920F52F
% Do you accept this certificate? [yes/no]: yes
Trustpoint CA certificate accepted.
步驟6.註冊信任點（獲取身份證書）。
IOS-CA(config)#crypto pki enroll <HeadEnd> % % Start certificate enrollment .. % Create a challenge password. You will need to verbally provide this password to the CA Administrator in order to revoke your certificate. For security reasons your password will not be saved in the configuration. Please make a note of it. Password: cisco123 Re-enter password: cisco123 % The subject name in the certificate will include: cn=HeadEnd.david.com % The subject name in the certificate will include: Connected_2_INET-B % Include the router serial number in the subject name? [yes/no]: no % Include an IP address in the subject name? [no]: no Request certificate from CA? [yes/no]: yes % Certificate request sent to Certificate Authority % The 'show crypto pki certificate verbose HeadEnd' command will show the fingerprint. *Jul 17 15:21:11.343: CRYPTO_PKI: Certificate Request Fingerprint MD5: 0017C310 9F6084E8 63053228 B449794F *Jul 17 15:21:11.343: CRYPTO_PKI: Certificate Request Fingerprint SHA1: CFE22C7A B2855C4D B4B2412B 57FC7106 1C5E7791 *Jul 17 15:21:15.675: %PKI-6-CERTRET: Certificate received from Certificate Authority
步驟7.驗證憑證。

步驟10.按一下「Next」。指示儲存PKCS12檔案的路徑。
步驟11.再次選擇下一步，並鍵入在crypto pki export <Win7_PC> pkcs12 <tftp://10.152.206.175/ Win7_PC.p12> password <cisco123>命令中輸入的密碼
步驟12.選擇下一步。
步驟13.再次選擇Next。
步驟14.選擇完成。
步驟15.選擇OK。現在您將看到已安裝的證書（CA證書和身份證書）。
步驟16.將CA證書從證書（本地電腦）>個人>證書拖放到證書（本地電腦）>受信任的根證書頒發機構>證書。
如何在Android流動裝置上安裝身份證書
步驟1。從PKCS12(.p12)格式的IOS CA伺服器匯出使用者端憑證後，透過電子郵件將檔案傳送到Android裝置。安裝完畢後，請點選檔案的名稱以啟動自動安裝。(不下載檔案)
步驟2.輸入用於匯出證書的密碼，在本例中，密碼為cisco123。
步驟3.選擇OK並輸入Certificate name。它可以是任何單詞，在本示例中，名稱為Android ID Cert。
步驟4.選擇「OK」，系統將顯示消息「Android ID Cert installed」。
步驟5。若要安裝CA憑證，請以base64格式從IOS CA伺服器擷取該憑證，並以.crt擴充檔儲存該憑證。通過電子郵件將檔案傳送到Android裝置。這一次，您需要透過貼上檔案名稱旁邊的箭頭來下載檔案。
步驟6.導覽至Settings和Lock screen and security。
步驟7.選擇Other security settings。
步驟8.導航至從裝置儲存安裝。
步驟9.選擇.crt檔案並點選完成。
步驟10.輸入憑證名稱。它可以是任何單詞，在本例中，名稱為calo_root-1。
步驟10.選擇OK，您將看到消息「calo_root-1 installed」。
步驟11.若要驗證是否已安裝身份證書，請導航到Settings/Lock Screen and Security/Other > Security Settings/User Certificates/System頁籤。
步驟12.要驗證CA證書是否已安裝，請導航到Settings/Lock螢幕和security/Other security settings/View security certificates/User頁籤。
為使用IKEv2的RA VPN配置ASA頭端
步驟1。在ASDM上，導航到Configuration>Remote Access VPN > Network(client)Access> Anyconnect Connection Profiles。在面向VPN客戶端的介面上選中IPSec(IKEv2)access， Allow Access框(Enable Client Services選項不是必需的)。
步驟2.選擇Device Certificate，然後從Use same device certificate for SSL and IPSec IKEv2中刪除檢查標籤。
步驟3.為IPSec連線選擇頭端證書，為SSL連線選擇 — 無。
此選項將實施加密ikev2、加密ipsec、加密動態對映和加密對映配置。
這是組態在指令行介面(CLI)上的樣子。

在CLI上。
tunnel-group-map enable rules
步驟8.導航到Configuration > Remote Access VPN > Network(Client)Access > Advanced > IPsec > Certificate to Connection Profile maps > Rules，然後建立新的證書對映。選擇Add並將其關聯到隧道組。在本示例中，隧道組名為David。
在CLI上。
tunnel-group-map CERT_MAP 10 David
步驟9.在對映條件部分選擇Add，然後輸入這些值。
欄位:發行商
操作員：包含
值：calo_root
在CLI上。
crypto ca certificate map CERT_MAP 10 issuer-name co calo_root
步驟10.使用要使用的IP池網路建立對象，以便在Configuration > Firewall > Objects > Network Objects/Groups> Add處新增（網路地址轉換）NAT免除規則。
在CLI上。
object network NETWORK_OBJ_192.168.50.0_24 subnet 192.168.50.0 255.255.255.0
步驟11.導航到Configuration > Firewall > NAT Rules，然後選擇Add為RA VPN流量建立NAT免除規則。
在CLI上。
nat (inside,outside) source static any any destination static NETWORK_OBJ_192.168.50.0_24 NETWORK_OBJ_192.168.50.0_24 no-proxy-arp route-lookup
這是用於此示例的完整ASA配置。
