Change in behavior of DNS Resolver for traffic coming from OpenVPN network



  • I have a OpenVPN client server setup and I have the firewall's LAN address set for the DNS server to push to clients.

    This worked fine until I updated to the current 2.3 release. After the update, clients were not able to query the DNS Resolver. After some trouble shooting and Googleing, I added the OpenVPN subnet to the Resolver's ACL. That fixed the issue!

    Did anyone else have the same issue?

    Was this change in behavior documented somewhere?
