Reference Manual for the Model RP614 v2 Web Safe Router
5-6 Advanced Configuration of the Router

Setting the MTU Size

The default MTU size is usually fine. The normal MTU (Maximum Transmit Unit) value for most
Ethernet networks is 1500 Bytes. For some ISPs, particularly some using PPPoE, you may need to
reduce the MTU. This should not be done unless you are sure it is necessary by your ISP.
Any packets sent through the router that are larger than the configured MTU size will be
repackaged into smaller packets to meet the MT U requirement. To change the MTU size:
1. Under MTU Size, enter a new size between 64 and 1500.
2. Click Apply to save the new configuration.
Using the LAN IP Setup Options
The second feature category under the Advanced heading is LAN IP Setup. This menu allows
configuration of LAN IP services such as DHCP and RIP. From the Main Menu of the browser
interface, under Advanced, click on LAN IP Setup to view the LAN IP Setup menu, shown below.
