Can ping gateway but nothing beyond

Hello all,
I’ve watched some videos and read the initial config document and while it really seems like I have set this up correctly, I just can’t get past the gateway.
Quick backstory is that this is for a business and we just had fiber installed. They put in what they call an ONT (which is sorta a modem and phone modem in one). In any case, internet will work with a normal router, even when that router is set up with one of the 5 static IPs we have available. So obviously something is wrong with my set up somewhere, I’m just not seeing it.
The whole point of this router is so each of our 3 networks will be using a separate static IP. I deleted the basic config on the router to get started because I did not want the Client DHCP, I want to manually route the IPs.
On Ether1, I put one of the static IP addresses. On ether5, I put the usual 192.168.1.1 for my laptop. I set up a route using the 0.0.0.0 and the modem gateway. Then in the NAT I put srcnat, with ether1 being the out interface and masquerade being the action.

I even went ahead and set up the DHCP server and changed my laptop to auto, after which it received the IP info from the router, so that is working as well. But, I just cannot ping anything past the default gateway.

Is there something else I may be missing? Anything else I need to configure or perhaps set up in a different way? Any advice would be wonderful.

Thank you

/ip route

You need a default route there that points at your gateway

/ip firewall nat

You need to have a MASQ or SRC-NAT rule to get out to the outside world.

put up an export of what you put in there and mung your IP addresses.

I managed to find the problem by the time this was posted. My small mistake was when I put in the default gateway under route, i put 0.0.0.0 instead of 0.0.0.0/0

That final /0 for the netmask was apparently the problem. Not I am on to trying to figure out VLANs between the router and a TP Link switch..
