I have the 500/500 Vantage Fiber service from Frontier in Connecticut. This service requires that you use both their own ONT and router (DHCP 802.1x). I am trying to properly configure the required ISP router (Arris) to be as passive as possible, and to let my Ubiquiti Dream Machine Pro (UDMP) do all the work.
This is the network layout:
ONT (ISP supplied/required) >> Arris NVG448B (ISP supplied/required) >> UDMP >> AP’s and Switch
So far I have been able to find the following methods:
1. Put Arris into bridge mode - Router has the option to do this, but if I do I am unable to get internet on the UDMP. It seems like this bridge mode prevents the router form completing whatever security check the ISP is asking for.
2. Set a DMZ on the Arris for the UDPM. - DMZ firewall mode set to IP Passthrough, with the MAC address of the UDMP assigned. WIFI disabled, no other devices connected to Arris.
3. Trick the ISP by swapping a managed switch in for the Arris as described in this linked post - https://community.ui.com/questions/How-to-eliminate-ATandT-gateway-from-a-UniFi-setup/6f471739-7694-4512-9bb9-d1c8728d929f
I currently have things configured as described in option 2. This produced the public WAN address on the UDMP (good), but is only getting me between 125/125 and 250/250 depending on when I do the speed test. When I go directly through the router I am pretty constantly able to get 400+/400+. I have also experienced a lot of packet loss notifications while playing ps4, and some buffering mid stream on Netflix. Things just don’t feel right with it and I am not satisfied.
I am thinking of trying option 3, however I haven’t heard of anyone using it with my specific ISP so I wasn’t sure if it would work. I don’t mind the ~$40 for a switch if it works well, or the potential tinkering if I lose power. The process of modifying the JSON file of the UDMP is something I haven’t done before, but everything seems manageable to me.
Any thoughts or alternate suggestions?
