Configuring MTU Settings
The Maximum Transmission Unit (MTU) is the size of the largest packet that can be
sent over the network. The default MTU value for Ethernet networks is usually
1500 bytes and for PPPoE connections, it is 1492 bytes.
To configure the MTU settings:
STEP 1 Choose Networking > Choose Networking > WAN (Internet) > IPv4 WAN
(Internet).
STEP 2 Choose the MTU type:
• Default—Unless a change is required by your ISP, we recommend that you
choose Default in the MTU Type field. The default MTU size is 1500 bytes.
• Custom—If your ISP requires a custom MTU setting, choose Custom and
enter the MTU size (in bytes) in the MTU Size field.
STEP 3 Click Save.
Configuring the MAC Address
The Cisco RV180/RV180W has a unique 48-bit local Ethernet hardware address.
In most cases, the default MAC address is used to identify your Cisco RV180/
RV180W to your ISP. However, you can change this setting if required by your ISP.
My IP Address Enter the IP address assigned to you by your ISP.
Server IP Address Enter the IP address of the L2TP server.
