RAD Data comm RIC-E1 Dhcp Relay, Read Protocol from DIP Switches, Operation with Default Gateway

RIC-E1Installation and Operation ManualAppendix D IR-IP Interface Module

Operation with Default Gateway

You can instruct IR-IP to send packets with destinations not located on the local LAN to a specific router, which is called the default gateway. The default gateway must be connected to the local LAN.

To use this option, enter the IP address of another router attached to the local LAN in the Default Gateway field.

Note
	It is very important to obtain the correct parameters from the system administrator
	or ISP. The most common problem when establishing an IP connection is incorrect
	configuration of IP parameters and default gateway. Do not try to guess these
	parameters.

DHCP Relay

IR-IP can operate as a DHCP relay for computers on its LAN. In this mode, the user does not need to configure the IP addresses and other related parameters for the PCs on the LAN: they receive the configuration from the DHCP server via the IR-IP module.

Figure D-10. DNCP Relay Operation

To configure the IR-IP as a DHCP relay:

•From the Quick Setup menu, select DHCP Server IP Address and enter the IP address of the DHCP server.

Note Leaving the DHCP Server IP Address field blank disables the DHCP relay.

Read Protocol from DIP Switches

Selecting YES for this parameter forces IR-IP router card to use the WAN protocol selected by section 2 of its DIP switch: PPP or Frame Relay.

If you want to be able to select the WAN protocol by means of the Protocol field (parameter 7) of the Quick Setup menu, select NO.
