Nat + Static Routes

Hi everybody, i have a trouble at home. i want to add a static route on my epmp1000
My Network config its like this:


I want to enable Nat for the network 172.16.20.0 and ping the host behind the router 172.16.10.254
i need to add normal static route via 172.16.10.254 but the statics routes disappear when i set the epmp1000 in nat mode.
Thanks

Hi @elbitor
you need to configure
eth1 of your router to 172.16.20.1

sorry the eth1 is 172.16.20.1
i made a mistake in he diagram
