Routing Question

Hello to all.
I am new to Mikrcotik technology so please keep it simple.
The scenario that I also have is prety simple.
I have a routerboard and one port (Eth5) of it is connected to the DSL router. I have activated to be a DHCP client and it works great.
I can ping also the internet.
The other port (Eth 1) is acting as a DHCP server on a different subnet than eth5 and DSL router are.
The dhcp works also fine on eth1 and gives addresses to the pc that I connect.


How can I configure the Eth1 port to see the internet ?
Thank you in advance!

You need a nat rule to masquerade out ether 5

Can you help me a little more?
Where to go , in whitch menu and what to try to do?
Thank you!
