Configuring IRIS in Router mode
All IRIS systems ship with operational mode set to “router”. In router mode the cable interface is
configured with a private interface and all cabled modems and CPEs attached to the cable
modems are automatically assigned IP addresses from this private addressing scheme.
You will need to configure the “Uplink Interface” or the Ethernet Interface with the ISP provided
configuration parameters. For the “Uplink Interface” enter the following
− IP address
− Netmask
− Gateway
− DNS Server
− Domain Name
) Do not change the “Cable CM Interface” or the “Cable CPE Interface” address.
Changing this will require you to edit the DHCP server configuration file manually.
You should change this address only if you wish to do so and know how to manually
program a dhcpd.conf file. Future releases of IRIS firmware will provide graphical
user interface to edit the DHCP server configuration files.
After entering these, click the “Save” button. For changes to take effect select ‘Reboot” from the
left hand side navigation bar.
Figure 11 Save and reboot
Confirm the reboot with selecting the “Reboot” button. After the reboot you should be able to
reach the “uplink” port of IRIS using the new IP address.
