Nighthawk router blocks microsoft remote desktop

Question

I bought a Netgear CM700 and Nighthawk&nbsp;R6700 - AC1750 for my internet through comcast xfinity at my new apartment. Everything works as expected except Microsoft Remote Desktop does not work to my work computer. My office uses a gateway and we have an IT guy who is only mildly available and helpful some of the time.&nbsp;Issue: I try to connect to my work computer through any device on my home network (hard wired or wifi) I get an error similiar to "An error occurred while communicating with the Remote Desktop Gateway. If this keeps happening, contact your network administrator for assistance.&nbsp;Error code: 0x300005f"&nbsp;Troubleshooting I've done:Restart modem and router - doesn't workUse windows, mac, chromebook (wifi) - doesn't workHard wire into router with windows laptop - doesn't workConnect using my iPhone as a modem - worksHard wire into Netgear modem (router not connected) - worksConnect to ExpressVPN and connect through router using wifi - works&nbsp;

I read through these topics but nothing new to try or any solutions provided. I did buy a different netgear router to see if that fixes the problem, and it does. I unplugged the R6700 and plugged in the R6230, restarted the modem and the R6230 works fine. My working hypothesis is that the R6700 is too "smart" for it's own good! Now just waiting the hear back from Netgear about returning the 6700.

Went to advanced tab, clicked internet port, changed DNS Address to "Use These DNS Servers", added 8.8.8.8 and 8.8.4.4, applied, router rebooted, tried to reconnect to MS Remote Desktop. Same error.

Went to advanced tab, WAN Setup, Checked box next to Default DMZ Server, entered IP address of my laptop. Router rebooted. Tried to reconnect MS Remote Desktop. Same error.

I also gave my laptop a static IP so it wouldn't keep moving every time I rebooted the router and tried setting up port forwarding for both port 443 and 3389 to my laptop's internal IP. Still same error.

I'm wondering if I should return my "smart" wifi router and buy a "dumb one" and hope that it's the smarts that are getting in the way of working from home. Maybe this router would work better? https://www.amazon.com/gp/product/B0756QFLXP/ref=ox_sc_act_title_2?smid=ATVPDKIKX0DER&psc=1

a couple things you can try.&nbsp;
1. try a different dns provider. try googles at 8.8.8.8 or 8.8.4.4
2. try putting the PC you're using into the routers DMZ
