USE AN ADSL ROUTER AS HOT SPOT OF ANOTHER ADSL ROUTeR

I have an adsl router SPEED TOUCH 585i with ip 192.168.1.254 which is connected to the adsl line.
I have connected a pc and i am connected to internet OK.
I want to connect 1 ethernet port of this routr with an ETHERNET PORT of a ZYXEL wifi adsl router( via a utp cable) so i can have anothe HOT SPOT 50 meters away.
What are the IP settings I must assign on the ZYXEL router?

THanking you in advance
