DHCP is not set up.

Assuming this is a Cisco router, this link will show you how:

DHCP is handled by your server, OK
I also just noticed that NAT is not configured.

well , sbcglobal sent me these settings

dslrouter(dhcp-config)#network 65.66.117.225 255.255.255.0
dslrouter(dhcp-config)#dns-server 151.164.1.8
dslrouter(dhcp-config)#default-router 65.66.117.230
dslrouter(dhcp-config)#domain sbcglobal.net
dslrouter(dhcp-config)#end

so i added them and someone tomo morning will test ( this is a remote site)

now they gave me a range 65.66.117.225 - .229
and i am not sure if i entered it right.... actually i know i did wrong cause my subnet mask is /24
