MG21 with MX68 connection layout



I have to perform a PoC with a customer next month. Presales ordered MG21 cellular gateway and a MX68 to secure and backup local internet access.

But they ordered only power supply for the MX68.

So I did something to power up the MG21, I use the PoE port 11 on the MX68 to port LAN1 of the MG21. Then I use the 2nd LAN port of the MG to connect the Internet 2Image 29-07-2020 à 12.28.18AM.jpeg interface of the MX68.


It looks like it's working but I think I would prefer a dedicated PSU for the MG. What do you think about that ?

That's actually how my MG at home is configured. Works fine, albeit Vodafone 4G in London isn't great so I only get about 5Mbps. Saves using an extra wall socket!

For this to work, did you need to create a new vlan that includes port Internet 2 and port 11 ?


Because I think what one of my colleague did once was (with an MS in the setup) :


1 switchport to MG21 poe port

1 switchport to Internet 2 (so Internet 2 not connected directly to MG21)


Those 2 switchports in same vlan



Hi @Jeizzen 


On my config, all ports of MX68 are in same VLAN (Vlan 101 with subnet (Something like On MG21, there is another subnet ( with DHCP server. Only Internet 2 is getting an IP on that subnet.


Not sure I properly answered 😊
