Problem
I am unable to resolve the Client VPN endpoint's DNS name.
Cause
The Client VPN endpoint configuration file includes a parameter called
remote-random-hostname. This parameter forces the client to prepend
a random string to the DNS name to prevent DNS caching. Some clients do not
recognize this parameter and therefore, they do not prepend the required random
string to the DNS name.
Solution
Open the Client VPN endpoint configuration file using your preferred text editor.
Locate the line that specifies the Client VPN endpoint DNS name, and prepend a random
string to it so that the format is
random_string.displayed_DNS_name. For example:
-
Original DNS name:
cvpn-endpoint-0102bc4c2eEXAMPLE.clientvpn.us-west-2.amazonaws.com -
Modified DNS name:
asdfa.cvpn-endpoint-0102bc4c2eEXAMPLE.clientvpn.us-west-2.amazonaws.com
