I have recently revamped my network for maximum user experience while maintaining some seperatation of broadcast packets with vlans. I have a very basic understanding of vlans and "lag groups." If anyone has any good advice please share.
So here's my setup:
Arris SB6190: 100/10 (EEE OFF)
Actiontec VDSL2:50/10. (Bridge mode)
TP-LINK ER5120
2-TP-LINK T1600G-28TS
2-NETDUMA R1
-------------------------------------------
I have the cable modem split to 2 50/5 WAN ports, WAN 1 dhcp WAN 2 Static ip #1. Vdsl is dhcp to WAN 3. LAN port from 5120 cascades to switch port 24. DMZ port of 5120 is direct to netduma with ONE to ONE NAT with Static IP #2 assigned to netduma private wan IP add. All general traffic uses wan 1 and 3 combined bandwidth rules allow 100/10 from WAN 1 and 3. DMZ traffic is set to use only WAN 2. I've created a vlan to handle the WAN addresses from the 6190 to er5120. I've created vlan to seperate security cam traffic. I've created vlan to seperate wifi devices connected through the APs. Currently everything works really really well. I can seriously download at 80 Mbps or 10-11MBps from newsgroups while my wife and kids watch netflix, youtube, etc and my ping just sits at 33ms stable. I really only use the Duma for the badass geofilter.
The biggest issue I have is my serviio server is now on a seperate subnet 192.169.99.10 and all of the ps4s are behind the Duma 192.168.98.xx. I could probably just create a route etc. But here's my plan. Tell me if I'm going to regret it or if their is a more efficient way to config.

I would like to keep the ER5120 at 192.168.99.1 with dhcp ON, move the dumas into that subnet on the LAN scope w/dhcp OFF say 192.168.99.5. Of course I'll have to figure out how to change the Duma address and also it will require all ps4 to have static IPS but that is what I've always done anyway. All ps4 have NAT type 2 OPEN. No problem there.

What I would like to do is aggregate the LAN ports of the Duma R1 into a tagged set of uplink ports from the T1600G-28TS. Is this possible? Is there a work around? Any ideas? I know it sounds like I'm going way overboard on the link aggregation but if it's possible why not have 4 gigabit between the LAN clients vs. 6 PS4s squeezing traffic through 1 gigabit uplink. As I see it, simply plugging several ethernet cables from the Duma lan ports to the defined Tagged vlan ports, attempting to trunk would just cause a typical loop. Maybe this can be an advanced feature implemented down the road.
Obviously to escape broadcast storm or "local congestion" with this config I will create a vlan for the Duma "clients" including the server port to allow serviio dlna service and then a seperate vlan for general lan including server port.

Dude who knows if this will translate well. AHAHAHAHAHA!

This can be closed.  I have since returned these devices.  I learned that the TP-Link router cannot support special character passwords, big deal if you are serving over public IPs, and the main reason the ER5120 AND ER6120 both have a maximum WAN throughput of 350Mbps.  I'm not into upgrading over and over as speeds increase from every ISP available to me.  Thats ridiculous to have a gigabit router with 1-4 gigabit WAN ports that cannot support more than 350Mbps throughput. Business class my ass. Now I have another dilema.
