Router-Switch-Router Question

Greetings networking folks,

Got 3 Ubiquiti devices (I know, I know, I accept all judgment) - 1 Switch 48 PoE devices, 1 EdgeRouter Infinity, 1 USG PRO 4 (router)

I have a setup similar to the following:

internet > L1 modem > USG-PRO-4 (192.168.1.1) > switch (192.168.1.0/24) > EdgeRouter > laptop (172.16.0.2)

​

My question is: I'm trying to route the laptop to the internet. Eventually the EdgeRouter will be implemented in an office with a Dual-WAN setup, but for testing purposes I want to familiarize myself with the EdgeRouter

What is the setup/what have I done:

1) configured IPs on 2 interfaces on the EdgeRouter (192.168.1.200 eth0, 172.16.0.1 eth7)

2) confirmed the laptop can ping both interfaces on the EdgeRouter

3) confirmed a device on the 192.168.1.0/24 network can ping both interfaces on the EdgeRouter

4) confirmed there are no firewall settings on the EdgeRouter (it has none on fresh deployment far as I can tell)

5) attempted creating a route using the following methods:

• set protocols static route 172.16.0.0/24 next-hop 192.168.1.1 < DIDN'T WORK
• set protocols static route 172.16.0.0/24 next-hop 192.168.1.200 < EdgeRouter errors out

6) The 192.168.1.0/24 network does not have a configured VLAN

​

Have tried Googling tutorials, but nothing that fits my particular scenario shows up. Experience with routers is Cisco Packet Tracer and SOHO routers, so if this is an absurd question I apologize for wasting anyone's time :)
