Wave Global Administrator Guide
• If you do not have a connection to an ISP or a WAN, use the standardized, unregistered,
non-connecting IP addresses set aside in RFC 1918 for your network interfaces. (In this
situation, you must change the default IP address for the Integrated Services Card, and
you can use Wave default IP addresses for your other network interfaces.)
• Do not assign IP addresses ending in .0 or .255 to individual machines, as these are the
network and broadcast addresses for Class C addresses.
Each Integrated Services Card in the Wave Server is an Ethernet segment with a network
interface to RRAS. Each network interface requires a valid static IP address and subnet mask
number.
The Wave Server is configured with a Integrated Services Card as an independent Ethernet
segment on Wave Servers that have only a Integrated Services Card installed. That card is
configured with a default static IP address of 192.168.205.1 and a default Subnet Mask of
255.255.255.0.
Note: You should have changed the default IP addresses of your Wave network interfaces
during initial configuration. You can continue to use the default IP addresses only if packets
destined for the Internet first go through a separate machine—not part of Wave—which
performs IP address translation, such as a proxy server or a Network Address Translator (NAT).
For more information on using a proxy server in an Wave network, see “Using a proxy server
with Wave” on page 30-7.
The following are additional guidelines for working with IP addresses and subnet masks:
• Router interface IP addresses typically end in .1. For example, if subnet 1 is 192.168.3.*,
its network interface IP address would be 192.168.3.1; if subnet 2 is 192.168.4.*, its
network interface IP address would be 192.168.4.1, and so on.
• Use the next logical number that is not currently assigned to assign new IP addresses.
• If your Wave Server is connected to an external DHCP server, modify the Wave default
IP addresses to use an IP address within the server’s subnet range. For example, if the
DHCP server address is 204.1.1.1, you might change the Integrated Services Card
address from 192.168.1.245
to 204.1.1.245, and set the Wave IP address range from
204.1.1.2 to 204.1.1.244. You must set this address, because the Wave Server cannot be a
DHCP client.
