SSL Clientless VPN Customization

hi all,

i'm trying to learn to SSL clientless VPN customization on ASA 5520 but i can't seem to add any.

is there a command or pre-requisite prior to customization? could it be java or asdm issue?

Re: SSL Clientless VPN Customization

"AnyConnect Premium Peers          : 2              perpetual" is the key bit there. Those are the two AnyConnect Premium peers included with all ASAs.

The "Other" and "Total" VPN peers account for the fact that you could also have up to 10 IPsec (remote access or site-site) VPNs plus the two remote access client VPNs active any any given time.

In general a remote access VPN can be:

a. Clientless SSL (only a browser required by the peer but, confusingly, requires AnyConnect Premium license on the ASA),

b. Full-tunnel SSL (launch via browser or directly from Anyconnect client, requires either AnyConnect Premium or Essentials on the ASA) , or

c. IPsec-based (using the legacy Cisco IPsec client with IKEv1 (no AnyConnect license required) or AnyConnect 3.0 or later client (with either Essentials or Premium license on the ASA) with IKEv2).

And there will be a test on all that.

SSL Clientless VPN Customization

You haven't by chance restricted the use of the required AnyConnect Premium license with an Essentials license (and  "anyconnect essentials") command have you? The rest of the "sh(ow) ve(rsion)" output should indicate if the device has the necessary Premium license available.

Hi Marvin,

Thanks for your reply! Actually, this is for my GNS3 lab. I would assume all licenses/feature are enabled (perpetual).

I haven't got the chance to try this out on my ASA 5505 and 5510 lab FW. But both are running Base licenses.

I was searching and I suspect i haven't setup any bookmark yet. Maybe will try again when I get the chance.

I don't use GNS3 as I have lab firewalls plus plenty of opportunity to implement as part of my day job.

While all features may be enabled, it is - at the end of the day - just an emulation. Not sure if it is related but some of the clientless and other VPN bits do depend on saving xml and other files onto the ASA disk.
