NetComm NB5 Ethernet/USB Modem Router YML717 Rev1
52 www.netcomm.com.au
By default, your ADSL Router has DHCP server (LAN side) enabled. This function will allocate
DHCP numbers to any network node on your LAN as required according to the settings above.
However, if you already have a DHCP server running on your network, you must disable one of the
two DHCP servers as the presence of two DHCP servers on one LAN will create conflicts and lead
to network problems.
To disable the DHCP function on the NB5, select the Server and Relay Off radio button. Caution: if
this function is disabled careful attention must be paid to the IP address setup of each computer on
the LAN as IP addresses will no longer be allocated automatically.
To save changes, click on Apply, then click on Save Settings.
Management IP
This will reveal the Management IP Address Screen. Caution: if you change the NB5 Default IP
Address, you will not be able to open the device in your browser using the previous IP address. You
will also need to Renew the DHCP Lease using the DHCP Configuration Screen to enable
reconnection of your Web session.
Static IP Address Assignment
Your NB5 Routers default IP Address and Subnet Mask are 192.168.1.1/255.255.255.0. This subnet
mask setting will allow the ADSL Router to support 254 users.
If you want to support a larger number of users the Subnet Mask can be changed but bear in mind
the DHCP server is defaulted to only give out 255 IP addresses.
If you have been allocated a Static IP by your ISP enter it in this field.
Caution: DHCP Configuration and Management IP: If you change your Router IP
address while DHCP is enabled, the DHCP configuration must reside within
the same subnet.
Default Gateway: is the routing device used to forward all traffic that is not addressed to a station
within the local subnet. The Default Gateway Address is provided by the ISP.
Hostname: can be any alpha-numeric expression that does not contain spaces. The domain name is
used to in conjunction with the host name to uniquely identify the gateway. To access the ADSL
Router's web pages the user can type 192.168.1.1 (the default IP address) or type mygateway.ar7.
