Open VPN Remote Users Connect, Windows Users Can't Load WebPages
I've got OpenVPN up and running for remote users. For those on macOS, everything works normally. They can reach resources on the lan and load web pages.
Windows users can connect and reach resources on the lan, but cannot load webpages. When they disconnect from VPN, they are able to load webpages again normally.
I currently have this configured for split-tunnel, but am stumped on what I could be missing that's preventing this from working as intended for windows users, but works fine for mac users.
I have any any allowed on the OpenVPN firewall rules for now as I troubleshoot this issue.
I should add that while connected to VPN from a windows machine, I can ping 220.127.116.11, but not google.com.
All of the symptoms appear to be DNS related. I'm pushing 18.104.22.168 and 22.214.171.124 from the OpenVPN configuration. I've also blocked access to remote DNS servers. Still no luck.
I also have an OpenVPN site to site tunnel between this pfsense box and another. I get the same symptom set on both pfsense boxes.
