Merlin OVPN Client leaks DNS requests

[nottryingtobelame]

Hello all, new here so if I'm in the wrong place, please point me in the right direction.

I recently flashed my RT-AC87U with 384.13_2. I imported an .ovpn file, setup the client, and connected to the VPN successfully. However, ipleak.net and dnsleaktest.com both show that there is a clear DNS leak.

I tried to set "dhcp-option DNS 10.x.x.1" but it made no difference. I saw another post suggesting that a time synchronization issue was causing that poster's DNS leaks (not sure how). I have ensured that my time zone is set correctly, and it is setup with 2 NTP servers. Looking at the system logs, the time appears to be correct.

Any information is appreciated; thanks in advance.

Edit to add/clarify: the same .ovpn file was known to be working on the Asus stock firmware without leaks.

Setting it to strict appears to have resolved my issue. Thank you very much!
