The following section contains additional technical information about the CellPipe 
7130 RG features described in this chapter.

DNS Servers Assigned by DHCP Server

If you do not configure DNS servers, the CellPipe 7130 RG uses its LAN IP address and 
tells the DHCP clients on the LAN that itself is the DNS server. When a LAN client sends a 
DNS query to the CellPipe 7130 RG, the CellPipe 7130 RG forwards the query to its 
system DNS server you configured in the WAN screen.

CellPipe 7130 RG passes to the DHCP clients.
