Overview
These are the steps to configure the Windows 7 and Android native VPN clients in order to connect to an ASA headend:
Configure Certificate Authority
The CA allows to embed the required Extended Key Usage (EKU) in the certificate. For the ASA headend, certificate Server Auth EKU is required, while the client certificate needs Client Auth EKU.
A variety of CA servers can be used such as:
- Cisco IOS CA server
- OpenSSL CA server
- Microsoft CA server
- 3rd party CAs
IOS CA Server is used for this configuration example.
This section outlines the basic configuration to make a CISCO1921/K9 with version 15.5(3)M4a work as a CA Server.
Step 1. Ensure the device and version support the eku command.
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
Step 2. Enable the HTTP Server on the Router.
IOS-CA(config)#ip http server
Step 3. Generate an exportable RSA keypair.
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)
Step 4. Configure a trustpoint.
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>
Step 5. Authenticate the trustpoint (Get the CA Certificate).
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.
Step 6. Enroll the trustpoint (Get the Identity certificate).
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
Step 7. Verify the certificates.
