CellPipe 7130 RG User’s Guide

The actual physical connection determines whether the CellPipe 7130 RG ports are 
LAN or WAN ports. There are two separate IP networks, one inside the LAN 
network and the other outside the WAN network as shown next.

Figure 37   LAN and WAN IP Addresses

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows 
individual clients to obtain TCP/IP configuration at start-up from a server. You can 
configure the CellPipe 7130 RG as a DHCP server or disable it. When configured as 
a server, the CellPipe 7130 RG provides the TCP/IP configuration for the clients. If 
you turn DHCP service off, you must have another DHCP server on your LAN, or 
else the computer must be manually configured. 

The CellPipe 7130 RG is pre-configured with a pool of IP addresses for the DHCP 
clients (DHCP Pool). See the product specifications in the appendices. Do not 
assign static IP addresses from the DHCP pool to your LAN computers.

The CellPipe 7130 RG has built-in DHCP server capability that assigns IP addresses 
and DNS servers to systems that support DHCP client capability.

Similar to the way houses on a street share a common street name, so too do 
computers on a LAN share one common network number.

Where you obtain your network number depends on your particular situation. If 
the ISP or your network administrator assigns you a block of registered IP
