USG FLEX 100H and 2.5 Gbit Internet Connection

MGK

Good morning everyone, I have a question to ask if anyone has already had this experience.
I have a 2.5 Gbit internet connection (Vodafone) but their router has a 2.5 port towards the ONT and 4 GBit ports towards the LAN.
My idea was to connect the two WAN ports of the USG100H to the router and balance the load with a LFF trunk in order to have a little more bandwidth on the connected computers since, in theory, the 2.5 Gbit of the connection would be divided between the 4 LAN ports.
Has anyone already done tests with a similar configuration?
Thanks for the answers

Hi @MGK ,

To better support you, please share detail your requirement and help to clarify the below items:

2.5 Gbit internet connection (Vodafone) but their router has a 2.5 port towards the ONT and 4 GBit ports towards the LAN.

Are you referring to 4 LAN ports with 1 Gigabit capability each?

the 2.5 Gbit of the connection would be divided between the 4 LAN ports.

Are these ports on the Vodafone router or the USG FLEX 100H?

Is your network topology as typology 1 or 2? If not, could you describe your setup?

Thank you Judy.

Topology 1

Hi @MGK ,

You can use Least Load First (LLF) for your network. In LLF mode, the firewall will calculate the WAN interface usage and transmit traffic by the least load interface.

The path to configure: Network > Interface > Trunk

Ok, thank you for the answer.

Small precision:
For Topology 1 to work, your Vodafone router must provide different addressing plans for each of the 2 WAN ports of the USGFLEX100H. (Example WAN1 192.168.10.0/24 and WAN2 192.168.20.0/24)
If your Vodafone router is a basic model (like an operator box) then it will only offer one addressing plan for all its LAN outputs so the 2 WAN ports of the USGFLEX100H will receive an IP address in the same addressing plan (Example WAN1 192.168.10.1 and WAN2 192.168.10.1) and I think that this will not work.
