pix with ca certificate

I want to test that IPSec Between PIX and Cisco VPN Client Using ca certificate.But pix can not get the certificate from CA server with Microsoft Windows 2003 Enterprise Server.I install the Simple Certificate Enrollment Protocol(SCEP) add-on for Certificate Service in CA Server.Connection test using command Ping between pix and CA server is ok.

Ip address of CA server is 192.168.22.167/24

pix:

domain-name test.com

ip address outside 192.168.22.166 255.255.255.0

clock timezone beijing +8

CA Server and pix located in the same timezone.

pix1(config)# ca generate rsa key 512

Keypair generation process begin.

.Success.

pix1(config)# sh ca mypubkey rsa

pix1(config)# ca identity cert 192.168.22.167:/certsrv/mscep/mscep.dll

pix1(config)# ca authen cert

Certificate has the following attributes:

Fingerprint: 1e5563c3 6b3e53e2 f9ebbd65 ce44dda4

I get below information from url http://192.168.22.167/certsrv/mscep/mscep.dll

The CA certificate's thumbprint is 72463416 7B80534A 5979369B 238DE32D.

Your enrollment challenge password is E7C44517867A6464 and will expire within 60 minutes. This password can only be used once.

Each enrollment requires a new challenge password. You can refresh this web page to obtain a new challenge password.

For more information please see the online documentation mscephlp.htm.

pix1(config)# ca enroll cert E7C44517867A6464

% No CA root cert exists. Use "ca authenticate"

Who can tell the reason and what could i do next?

Thanks a lot

Re: pix with ca certificate

Hello,

Between the commnads:

pix1(config)# ca identity cert 192.168.22.167:/certsrv/mscep/mscep.dll

and

pix1(config)# ca authen cert

Normally should also be used:

ca configure ca_nickname ca | ra retry_period retry_count [crloptional]

at least in pix version 6.2.

Re: pix with ca certificate

Hi

Maybe this help you:

check the timezone and be sure it sould be gmt ,also syncoronize your pix Date & Clock with ca server Date & clock.

Thanks.

Re: pix with ca certificate

I am sure that I configure the same timezone on pix515 and CA server.

But the way, I add a router 2811 to my experiment and the router can get a certificate from CA server.Vpn client(version 4.6.01) also got a certificate from CA server.But vpn client can not dial-in with rsa-sig authentication.Attachments are configuration of router and debug information.

I can not find the reason now.Could anybody else do the same experiment and give me some suggestion.

Thanks a lot.

Re: pix with ca certificate

Hi

I only know little how to configure vpn and ipsec on a pix firewall.

have you configured """vpngroup vpngroupname ....""" on your pix ?

If you ve configured this be sure the name of the department as same as the name of vpngroupname when you want to complete the certification form to request a new certificate.

Thanks.
