DNS name resolution does not work
Posted: Thu Mar 02, 2017 5:04 am
Hello All,
We are having issues on some computers that connect via OpenVPN where name resolution does not work. Most of the employees in our company work from home and some have to remotely login to our office network to access our Shares and VMWare servers etc. We have Comcast as our Service Provider and their IP range is 10.0.1.2-10.0.1.254 in our office.
We setup the OpenVPN appliance as a Virtual machine and we configured it to provide an IP in the 10.0.2.x range with a routing added back to 10.0.1.0/24.
When users connect using OpenVPN client, they are assigned the 10.0.2.x IP, however they cannot issue a ping by hostname or nslookup a host or IP address. they CAN ping by IP address, which is not ideal, because they now have to remember the IPs of the servers that they want to connect to. They could eventually get used to it, but we want to understand why this isnt working and if we have it setup wrong.
We tried the Bridged Mode setting in the settings page for OpenVPN, and that puts us on the same subnet as our office servers, but we still CANNOT ping servers by hostname while we are on the VPN. I am one of the users affected and I can definitely ping the servers by hostname when I am physically in the office. When I work from home, I cannot ping the servers or access them by hostnames. I can only use IP addresses.
We have a ticket open with OpenVPN, but their support hasnt been very responsive.
Any suggestions on what to look for or what information you need from me to help me troubleshoot further would be greatly appreciated.
Regards,
DK
