Trying to set up a VPN

I thought an SSL VPN would be good but everytime I go to connect to it I have click through security warnings and install a securty certificate. Other than that the VPN works, however there will be less tech savy (and paitent) users using this vpn, and they will not want to have to click through a bunch of security warnings to get to the VPN. So is there a way I can have the user connect to a web portal once and that will download the VPN any connect software on thier computer then after that all they have to do is open the any connect software and type in a username and password and preferably have the vpn software remember the ip address for them? Also if this could be done via CCP that would be great, I'm new to Cisco routers and don't know the command line yet. If it can't be done via ccp then I guess I'll have to bite the bullet and do it via command line. Thanks.

Re: Trying to set up a VPN

The problem is that you configured to use keypair "test" in the trustpoint but you did not generate the key with label "test".

Please following the extactly steps below.

1. generate a key with name "test"

crypto key generate rsa modulus 1024 label test

2. remove "ip domain name" If it is configured

no ip domain name xxxx.xxx

3. configure your trustpoint like following

crypto pki trustpoint self-signed
enrollment selfsigned
fqdn
subject-name CN=
rsakeypair test

4. change your host name to IP address.

hostname

5. crypto pki enroll self-signed

6. change your hostname back to its previous name.

7. add "ip domain name" back

8. change webvpn config to point to the new trustpoint

webvpn gateway gateway_1

ssl trustpoint self-signed

Then try the webvpn by using your public IP.

Re: Trying to set up a VPN

On the SSL VPN client, you need install the certificate of root CA which issued the certificate to your SSL VPN Router/ASA. The root CA should be in the trusted list as well in your client's computer.

Re: Trying to set up a VPN

What do you mean by on the ssl client I have to install a certificate? When I access the vpn web portal through the ip address I get to a page where I type in a username and password then form there I go to a Cisco SSL VPN service page I click on the start button by tunnel connection then I get a whole bunch of certificate warnings then I get a screen that asks me to install the certificate. I do that and then I am able to connect to the vpn. But this happens everytime I need to connect to the VPN. I've seen cisco VPNs where I just open up the Anyconnect cliet on my computer and choose the ip from a drop down list then it asks me for a user name and password once I enter those I am connected to the vpn with no hassel.

Re: Trying to set up a VPN

Since you are using self-signed cert, please following the following link to add it to the trusted root cert.

http://www.cisco.com/en/US/docs/security/vpn_client/anyconnect/anyconnect23/administration/23admin2.html#wp1026122

You should be able to use your SSL Anyconnect client from Start->All Programs-->Cisco->Cisco Anyconnect VPN Client.

Re: Trying to set up a VPN

Ok I must be missing something here. Because here are the steps I followed:


Step 1 Go to Tools | Internet Options | Trusted Sites.

The Internet Options window opens.

Step 2 Click the Security tab.

Step 3 Click the Trusted Sites icon.

Step 4 Click Sites.

The Trusted Sites window opens.

Step 5 Type  the host name or IP address of the security appliance. Use a wildcard  such as https://*.yourcompany.com to allow all ASA 5500s within the  yourcompany.com domain to be used to support multiple sites.

Step 6 Click Add.

Step 7 Click OK.

The Trusted Sites window closes.

Step 8 Click OK in the Internet Options window.

And

Step 1 Click View Certificate in the Security Alert window.

The Certificate window opens.

Step 2 Click Install Certificate.

The Certificate Import Wizard Welcome opens.

Step 3 Click Next.

The Certificate Import Wizard - Certificate Store window opens.

Step 4 Select "Automatically select the certificate store based on the type of certificate."

Step 5 Click Next.

The Certificate Import Wizard - Completing window opens.

Step 6 Click Finish.

Step 7 Another Security Warning window prompts "Do you want to install this certificate?" Click Yes.

The Certificate Import Wizard window indicates the import is successful.

Step 8 Click OK to close this window.

Step 9 Click OK to close the Certificate window.

Step 10 Click Yes to close the Security Alert window.

The security appliance window opens, signifying the certificate is trusted.

But the next time I open the web portal I have to install the certificate again

And when I try to connect via anny connect (without going through the web portal) I get The security alert box, go through the steps to install a certificate, but thenm I get the error unable to process response from *host ip address*

Re: Trying to set up a VPN

I think the issue might be related to self-signed certificate here.

I will run a lab testing on this when I get chance.

Re: Trying to set up a VPN

Ok, I did not forget your question and ran a quick lab testing on this.

So basically the issue is related to your self-signed certificate.

Here is what I did.

1. Generate the self-signed certificate like the following

crypto pki trustpoint self-signed
enrollment selfsigned
fqdn hostname.test.com
subject-name CN=hostname.test.com
rsakeypair test

Then, crypto pki enroll self-signed

2. When you access WebVPN, you must use "hostname.test.com" instead of IP address. In this way, after you install the certificate, it won't popup any alert message anymore.

3. You can add "svc keep-client-installed" in your policy. The the user can lauch the client from start->all program->Cisco->Cisco AnyConnect VPN client.

Re: Trying to set up a VPN

Would the network need to have a public domain name for that to work? They don't have a public domain that's why I was setting it up using the ip address.
