| how do i use     
					the public ip if isp gives me several public ips? if you can get a ranges of public ips
                             via pppoe, you can enable 2nd subnet to let pcs with public ip addresses
                             to access internet behind vigor2900.  please set one of the public ips and
                             their subnet mask as below. then you can set one of the static public ip to a pc on lan.
