Orbi mesh router (RBR850) with an ATT Gateway (BGW320-500) 5Gb Fiber

I just had 5g Fiber installed today and my question is about using the BGW320-500 as my router and placing the Orbi in AP mode. I had 1Gb fiber before and I put the BGW in passthrough and used the Orbi as the router and every thing worked perfectly, but with 5Gb I want to hardwire my server to the BGW's 5G port and the Orbi to one of the 1Gb ports so my server and wifi devices are on the same 192.168.1 subnet... otherwise my server will be on the 192.168.1 and the Orbi gives out the 10.0.0

Are there any known issues with this method, or is there a better way?

While the Orbi and the BGW have to be on different subnets, they can be anything you want.  But the problem is that anything that connects to the Orbi can't communicate with the server if it's plugged into the BGW.

Just curious why you want the server on the 5Gbps port.

Well I now have the Orbi in AP mode and it is allowing the BGW to assign the IPs to the wireless clients. All the wireless clients are getting 192.168.1 IPs, and my server connected to the 5Gb port is on 192.168.1.67

All the wireless devices can ping each other, but I can't ping the server, and the server can't ping any of the wireless devices.

Is there a setting on the BGW that would stop the Orbi clients from talking to the 5Gb port even though they are all apparently on the same subnet?

(and to answer the previous question, my server also acts as my main automated download client, hence why I want it on the 5Gb port.)

Well, I've never had a BGW320 and never had >1Gbps service so I can't say for sure but I can't think of anything that would jump out based on the settings I've seen in the other gateways.

Did you do a factory reset on the BGW since it's been in IP Passthrough mode?

yes, thanks for that, I saw something similar earlier but I don't see any option to set any firewall rules on the BGW.

Again, don't have access to a 320 but if the 210 I have is the same I'd think you can add a Pass Rule(s) at the bottom of the listing at http://192.168.1.254/cgi-bin/packetfilter.ha

thanks so much, I do see the option to add Pass Rules, not sure what I'm doing but will try to read up on it and see if it could help me...
