Hello,
Recently I've updated my MT3000 to v4.6.0-op24 due an issue with Captive Portal here
Before the upgrade when connecting to the OpenVPN profile was using the custom Upstream DNS from my OpenVPN config, however now, after connect the VPN is like he's not sending correctly the DNS requests. If i connect directly to the same OpenVPN profile from my computer I'm able to resolve the internals URLs using my DNS servers.
I've tried to set Custom DNS Servers directly instead of automatic (in Automatic I see the DNS Servers from the OpenVPN), also tried to edit the host file to see if he's able to resolve internally but no luck.
