Using Netgear N300 as a modem only

Telkom gives a Netgear N300 modem to their new customers. If you want to use it as a modem only and dial from another router (I use a TP-link router running OpenWRT), follow these easy steps.

Force a 10.0.0.0/8 range IP on your computer (I used 10.0.0.3) and connect to 10.0.0.2 in your browser, the default username and password is usually admin:admin or admin:<blank>.

Then go to 'Setup > Basic Settings', at 'Does Your Internet Connection Require A Login?', set it to 'No', make sure 'Enable' is ticked under 'NAT' and select 'Apply'.

Next go to 'Advanced > WAN Setup', make sure 'Enable PPPoE Relay' is ticked and 'Apply'.

Then go to 'Advanced > LAN Setup', untick 'Use Router as DHCP Server' and 'Apply'.

All that is left is to plug a cable from the modem into the WAN port of your chosen router and dial a PPPoE connection with your Telkom login details.
