Routes - what should I do?

[farmersLSD]

Question about routes.  I can change this, I just set it up to access the firewall if the LAN settings weren't correct.  Not a firewall expert here, but can usually figure it out.  On our Fortinet, we have to statically assign the route from 17.16.0.0/16 to 192.168.1.2 as the Gateway.  Our internal network being 172.16.0.0/16 and the gateway being our core switch at 192.168.1.1.

Here are our routes now:

Should I just delete the Management LAN and use the LAN interface and set it's route to 172.16.0.0/16 with a gateway of 192.168.1.2?

I just want easily be able to access to make changes in the event I don't have something correct. 

Under Interfaces, I have the LAN Interface set to 192.168.1.2 as the Gateway.  Just not sure, looking at the routes, if I needed to do anything else.  Since it shows link#, and 192.168.1.0/24 and 172.16.0.0/16 have different links.

Hopefully that's clear enough.

Short story:
I can ping out and into LAN from the firewall.  I don't get a response from my workstation to internet OR firewall.
