One of my clients would like to migrate their VPNs from OpenVPN to an ASA solution, and their current configuration uses the 'allow-pull-fqdn' feature of OpenVPN. When they connect to the VPN, as well as receiving the usual list of split-tunnel routes, this feature apparently allows DNS names to be sent, which are then resolved to IP addresses and entered into the routing table.
The feature is useful for DNS entries that change frequently, in my client's case to point towards a cloud-hosted service.
Please could you advise how the same could be achieved on an ASA.
