Description (partial)

Symptom:
AnyConnect VPN keeps trying to reconnect the tunnel, without success.

Conditions:
- Platform: macOS
- Dynamic split include tunneling configured in the head end group policy
- Local host name registered in DNS, with the A record's IP address being the IPv4 address assigned to the physical adapter used to establish the VPN tunnel.
- A local app attempts to connect to the local host by name, which results in a DNS request packet on the wire, followed by receipt of the corresponding DNS response.
