GL-MT6000 (Flint 2) Multi-WAN Load Balancing using WAN & LAN5

Hello support team and fellow users,

I had a query in regard to Flint 2 (fw v4.7.4) being used in the following Multi-WAN scenario:

Down Speed   |  Ports                    |        GL-MT6000 Port            | Use Case
-------------------------------------------------------------------------------------------
1 Gbps          ISP LAN1 (2.5 Gbps)      ->       WAN (2.5 Gbps)            | Multi-WAN 1
1 Gbps          ISP LAN1 (2.5Gbps)       ->       LAN5 (1 Gbps)             | Multi-WAN 2

2 Gbps          Switch LAN (2.5Gbps)     ->       WAN/LAN1 (2.5Gbps)        | LAN 1

The main reason for this need, is that, I have 2 WAN's that both have 1 Gbps down, with Multi-WAN enabled, I will be able to aggregate 2 x 1 Gbps down links (WAN and LAN5) into a 2 Gbps down link. Thus, I would like to reserve a 2.5 Gbps LAN link to a 2.5 Gbps switch as the network link to a PC with a 2.5 Gbps NIC to maximise potential down link speed.

The first topic was for Flint 1 was related to LAN1, not LAN5:
GL AX1800 FW 4.5.16 -- unable to convert LAN1 for a second ISP WAN port - Technical Support for Routers - GL.iNet

The other topic for Flint 2 but using MWAN3:
GL-MT6000 (Flint 2) Load Balance help](GL-MT6000 (Flint 2) Load Balance help - #5 by Caldas)

The last topic is exactly what I want to do, but doesn't outline the steps to achieve this:
GL-MT6000 (Flint2) How change LAN2 - LAN5 port to WAN

All topics require the use of LuCI and some require additional packages, but I believe this cannot be configured natively from GL Admin Panel - Network Port Management which isn't ideal for new router owners.

Question 1: Is it possible to request a feature (if not already in feature list) to use GL Admin Panel - Network Port Management to automatically configure any LAN port to WAN port in the Multi-WAN scenario?

Meanwhile, Question 2a: Is the right way to achieve the following steps without using the GL Admin Panel:

1. Disable kmwan:

uci set kmwan.global.enable=0
uci commit kmwan
/etc/init.d/kmwan stop
uci set kmwan.wan.disabled='1'
/etc/init.d/kmwan disable

Question 2b: Will this configuration persist after the next firmware update?

2. Install and configure mwan3 as per OpenWRT mwan3 guide:
Use Plug-ins to search and install mwan3, and luci-app-mwan3

Question 3a: Doing so would mean no access to view status or settings of Multi-WAN configuration using GL Admin Panel?

Question 3b: Are there any conflicts (apart from kmwan), that I should be aware of?

Question 4: Am I missing something, or, is there an easier way to do this whilst keeping native GL firmware (apart from going vanilla OpenWrt)?

OpenWrt details:

GL.iNet Flint 2 firmware v4.7.4
OpenWrt 21.02-SNAPSHOT r15812+1084-46b6ee7ffc / LuCI openwrt-21.02 branch git-22.335.71649-0ecaf74
All WiFi's are disabled, only using ethernet ports.

Thanks for your help and consideration for new feature.

Hi,

A1, I will record this requirement and submit it to the PM for evaluation.

A2a, the method of disabling kmwan is correct.

A2b, kmwan will not be restored to startup as long as it is not reset firmware.

A3a, yes, if kmwan is disabled, the Multi-WAN function will fail.

A3b, hardware acceleration maybe also needs to be disabled.

A4, this is the simple way.

Thanks @bruce.

In regards to A3b, are you suggesting that keeping hardware acceleration on whilst using mwan3 will not work properly?

How can I disable/enable hardware acceleration?

just says possible that Network Acceleration is enabled may will affect mwan3.

You can keep it on first. and if the mwan3 not work properly, then disable the hardware acceleration:
