IP Setup 8-13IP Address PoolsThe IP Address Pools screen allows you to configure a separate IP address serving pool for each of up to eightconfigured Ethernet IP subnets:This screen consists of between two and eight rows of four columns each. There are exactly as many rows asthere are Ethernet IP subnets configured on the IP Subnets screen.■ The Subnet (# host addrs) column is non-selectable and non-editable. It indicates the network address ofthe Ethernet IP subnet for which an address pool is being configured and the number of host addressesavailable on the subnet. The network address is equal to the router’s IP address on the subnetbitwise-ANDed with the subnet mask. The host address count is equal to the subnet size minus three,since one address is reserved for the network address, one for the subnet broadcast address, and one forthe router’s interface address on the subnet.You can edit the remaining columns in each row.■ The 1st Client Addr and Clients columns allow you to specify the base and extent of the address servingpool for a particular subnet. Entering 0.0.0.0 for the first client address or 0 for the number of clientsindicates that no addresses will be served from the corresponding Ethernet IP subnet.■ The Client Gateway column allows you to specify the default gateway address that will be provided toclients served an address from the corresponding pool. The value defaults to the Netopia 4541/4542’s IPaddress on the corresponding subnet (or the Netopia 4541/4542’s default gateway, if that gateway islocated on the subnet in question). You can override the value by entering any address that is part of thesubnet.DHCP, BootP, and dynamic WAN clients may receive an address from any one of the address serving poolsconfigured on this screen.IP Address PoolsSubnet (# host addrs) 1st Client Addr Clients Client Gateway--------------------- --------------- ------- --------------192.128.117.0 (253) 192.128.117.196 16 192.128.117.162192.129.117.0 (253) 192.129.117.110 8 192.129.117.4
