I need some help with setting up some basic routing.

My dsl router has a static route that routes all traffic for 172.17.0.0 through 172.16.0.5.
From the 172.17.0.0 network I am able to ping/access devices on the 172.16.0.0 but I do not get internet on the 172.17.0.0 network unless I enable NAT on the Miktorik. I’m not sure what I’m missing to get internet to work WITHOUT NAT on the Mikrotik device. The only routes on the Mikrotik are the dynamic ones.
