ASA5510 - Accessing Anyconnect via other local Interface

Hello - I hope someone can help.

I have a scenario where there is an ASA5510 configured as follows:

Interface0 = Outside

Interface1 = LAN

Interface2 = DMZ

Interface3 = unused

Running ASA version 8.2[1]

All network operations are fine, as are the IPSEC tunnels to other branch offices, and the incoming SSL VPN accessed via the IP address assigned to the external adapter.

My problem is that I have a device on the DMZ that needs to access the AnyConnect service hosted on the external adapter so that it can access LAN resources.  When I try accessing it, I see the following errors appearing in the debug log:

3Dec 03 201212:10:50710003[DMZ client address]51031[AnyConnect ExternalAddress]443TCP access denied by ACL from [DMZ client address]/51031 to DMZ:[AnyConnect ExternalAddress]/443

If you look closely, it suggests an ACL issue from the DMZ client to the external AnyConnect IP address BUT it suggests the Anyconnect IP address is on the DMZ interface.

Has anyone seen this before? 

Thanks in advance for any help.

ASA5510 - Accessing Anyconnect via other local Interface

In this scenario, you will have to enable Anyconnect on the DMZ interface for letting DMZ users to establish an Anyconnect tunnel and allow access of LAN resources since from DMZ or any other LAN interface you cannot directly VPN on External interface.

For reference, check https://supportforums.cisco.com/message/3801168#3801168 as similar discussion has happened in it as well.
