i have a linksys wrt160nl router connected to internet, to extend the range i have connected linksys wrt320n,through lan port (with dhcp/nat/firewall disable) and it working fine, i have connected one aztech dsl605ew to wrt160nl through lan port,(disabled dhcp and enable dhcp relay ) but i am not getting ip address, but i am able to ping ,is there any additional setting in aztec to be done to get the ip from wrt160nl dhcp ?
