I have a new installation where I have several remotes connecting to an ASA5500 router through the Cisco VPN client.
They connect fine, and I can ping around the network with no trouble. The problem is that the remotes cannot address any machine on the internal lan by name. The DNS server is at 10.21.0.100
Below is the configuration:
