OnCell G3100 Series Using the Web Console
DNS relay (default=Enable): If you enable DNS relay, your computers will use the router as a DNS server. If
you disable DNS relay, transfer the DNS server information from your ISP to your computers.
Start IP address: Enter the starting IP addresses for the DHCP server's IP assignment.
Maximum dynamic users: Enter the number of dynamic users. The maximum users you can enter may not
exceed 253, if your dynamic IP address begins with 192.168.127.1
Note: If you statically (manually) assign IP addresses to your computers or devices, make sure the IP
addresses are outside of this range or you may have an IP conflict.
Client lease time: The length of time for the IP address lease. Enter the Lease time in minutes.
Static IP mapping: If enabled, the mapping list allows you to assign the DHCP IP within the range to your
specific device from MAC address.
DNS Settings
DNS server 1: This is an optional field. If your network has access to a DNS server, you may enter the DNS
server’s IP address in this field. This allows the OnCell 5000 to use domain names instead of IP addresses to
access hosts.
The Domain Name System (DNS) is used to identify Internet domain names, and translate the names into IP
addresses. A domain name is an alphanumeric name, such as www.moxa.com, that it is usually easier to
remember than the numeric IP address. A DNS server is a host that translates this kind of text-based domain
name into the actual IP address used to establish a TCP/IP connection.
When the user wants to visit a particular website, the user’s computer sends the domain name (e.g.,
www.moxa.com) to a DNS server to request that website’s numeric IP address. When the IP address is
received from the DNS server, the user’s computer uses that information to connect to the website’s web
server. The OnCell 5000 plays the role of a DNS client, in the sense that it actively queries the DNS server for
the IP address associated with a particular domain name. The following functions in the OnCell 5000’s web
console support the use of domain names in place of IP addresses: Time Server, Destination IP Address (in TCP
Client mode), Mail Server, SNMP Trap Server, and SMTP Server.
DNS server 2: This is an optional field. The IP address of another DNS server may be entered in this field for
times when DNS server 1 is unavailable.
