Can't get new Fiber static IP to work [Edgerouter ER8]

So, we recently had fiber installed and with it came a new static IP address. So I unplugged from our previous modem and plugged into the demarcation panel. Of course, there is no internet.

This is the new info they gave me:

IP: 70.XXX.XXX.0/29
Gateway: 230.1
Subnetmask: 255.255.255.248

Currently, our config looks like this:

So I tried changing the IP in the GUI to 70.XXX.XXX.2/29
(.2 becuase it said cannot assigned network address as IP address)

But I still have no internet. Any ideas on what to do? The subnet mask likely changed as the old IP was /28 and .240 ending.

I'm a lost system admin, any help would be greatly appreciated!
