How do I delete a VPN on ASA?

If you need to remove a VPN from your ASA, the process is actually quite simple. Just follow these steps:

1. Log into the ASA’s web interface and go to the “VPN” tab.

2. Under the “IPSec Tunnels” section, find the tunnel that you want to remove and click on the trash can icon next to it.

3. Confirm that you want to delete the tunnel by clicking “OK.”

That’s all there is to it! Once you’ve deleted the IPSec tunnel, the VPN will no longer be active on your ASA.

Assuming you have your ASA and Windows PC ready:

1. Connect the ASA to the PC using the provided USB cable
2. Follow the on-screen instructions to install the ASDM launcher
3. Once installed, open the ASDM launcher and log in with the username and password you created during setup
4. Click on Configuration in the left menu and select Device Setup
5. In the System Settings section, click on Interfaces and then Add/Remove Interfaces
6. Select which interfaces you want to use for your VPN connection (usually LAN & WAN) and click OK
7. Next, go to Firewall under Configuration and select Access Rules
8. Click Add Rule and create a rule that allows traffic from your LAN interface to go through to your WAN interface

Now that your ASA is configured, you can continue setting up your VPN server by following our guide on How to Set Up a Site-to-Site VPN with an ASA 5506 .

Worth knowing

If you’re troubleshooting a VPN issue on your Cisco ASA, one of the first places you’ll want to check is the VPN logs. By default, the ASA doesn’t enable logging for VPN connections, so you’ll need to explicitly turn it on if you want to capture this data. Here’s how:

First, open up the ASDM and navigate to Configuration > Device Management > Logging > Syslog Setup. Check the “Enable Syslog Messages” box and click Apply.

Next, go to Configuration > Firewall > expand Advanced Features and double-click on System Settings. Scroll down to “IKEv1/IKEv2 Policy Based Routing Logging” and select “ALL”. Click Apply again.

Now all of your VPN traffic will be logged and you can view it by going to Tools > Monitoring > Syslog Messages. You can filter the results by various criteria, such as date/time range or message type (e.g., IKE messages only).

Worth knowing

If you’re looking to configure an IPSec VPN tunnel on your Cisco ASA 55xx, there are a few things you’ll need to do. First, you’ll need to configure IKE. This will involve establishing a policy for the supported ISAKMP encryption, authentication Diffie-Hellman, lifetime, and key parameters. Next, you’ll need to create an Access Control List (ACL). Once that’s done, you can configure IPSec. Finally, you’ll need to configure the port filter and network address translation (NAT).

Worth knowing

If you’re using a VPN, there’s a good chance that you may want to delete your current settings at some point. Maybe you want to switch to a different provider, or maybe you’re just done with VPNs altogether. Whatever the reason, deleting your VPN settings is pretty easy to do.

First, open up the Settings app on your device. Scroll down and tap on General. From there, scroll down and tap on VPN. You should see a list of all the VPNs that are currently configured on your device. Simplytap on the one that you want to delete and then tap Delete VPN in the popup menu that appears.

And that’s all there is to it! Once you’ve deleted your desired VPN configuration, it will no longer be accessible from your device.
