VPN Routing Issue - Please Help a Noob

JohnRKlein · Post by **JohnRKlein** » Sun Aug 13, 2023 4:59 pm

I'm trying to create a simple OpenVPN to my home network so I can access it while on the road. I setup the OpenVPN Service on my Router. I setup the OpenVPN Client on my Windows 10 PC. Exported the config from the Router and imported to the PC. Connected my PC to my phone's Hot Spot. Connected the VPN successfully. I can ping most items in my network using the IP address. (Not sure way some are not accessible yet.)

What can I do so the host names work? TRACERT finds the names, but I cannot use them directly. I feel this has to do with a gateway configuration somewhere.
