MX250 1 x USB (cellular failover1 )

[JED2021]

Is there any information  regarding the Cellular failover for the MX250 in case I lose both WAN 1 and WAN 2.

I undertsnad this is just a last gasp

@JED2021 : I would also recommend you to check the below thread, apart from what @alemabrahao shared !

I don't think I would rely on cellular failover for something as "core" as an MX250.

I think what I would do is get an MX67C, plug your second Internet circuit into that, put in a SIM card for cellular failover, and then plug the LAN of the MX67C into WAN2 of the MX250.

I have 2 WAN already.  I am looking for a way to at least get to the internet for slack and support.

We sent everyone home for the day  but had to walk around to notify people so a last gasp would have been helpful

this is a couple years back, i thought i ask regarding your suggestion.  I have this setup, but using another device, so i can have a 3rd wan (5g).

all seems to be fine, my question is while the 250 wan2 is on dhcp i have a private ip, assuming this will be double nat, it does show the public static ip on wan2.

on my third party device with the secondary internet circuit, i setup port forwarding to the 250's private ip, disable all IPS on the 3rd party device etc.

i am using traffic shaping rules on the 250 on wan2 to prefer some subnets to use, like my guests, iot etc.

tested with load balancing, no issues at all - showing public static ip's ok.

i know some other models have the 3rd wan capability, be nice if they implemented on the 250.

is there anything else you would recommend?  thanks mate.
