Hello there,
I own an Archer D7 router.
Firmware Version:1.6.0 0.9.1 v002d.0 Build 160216 Rel.57110n
Hardware Version:Archer D7 v1 00000002

I need to set up port forwarding on certain ports because I experience packet loss, I searched for this option on my configuration page for this router and the only thing I'm able to find is Port Triggering (which is a different thing) and DMZ, those two were found in Nat Forwarding under Advanced Tab
Please tech support let me know if this option is possible on my router's brand, and if it's the case, where to find the option on the config page?.
Thank you in advance for all the answers given.
