Title: [WORKAROUND] OpenVPN Clients cannot access unbound DNS
Post by: lox on January 23, 2018, 08:34:30 am

Hello,

I have added the VPN interface in the Unbound settings, it added my OpnVPN network to the access list (10.11.0.1/32)

From the VPN connected devices I can query any DNS server but the firewall's. I get a "REFUSED" response.

Here are the unbound logs:

Code: [Select]

Take a look here. It has a workaround.
