Chapter 4 Using Network Connections
MTU MTU (Maximum Transmission Unit) specifies the largest packet size per-
mitted for Internet transmission. “Automatic” sets the MTU at 1500. Other choic-
es include “Automatic by DHCP,” which sets the MTU according to the DHCP
connection, and “Manual,” which allows the MTU to be set manually.
Internet Connection Firewall
Click in the “Enabled” check box to activate the Router’s firewall on the Ethernet
connection. Actiontec does NOT recommend activating this feature.
Additional IP Addresses
Clicking New IP Address generates the “Additional IP Address Settings” screen,
where additional IP addresses can be created to access the Router via the
Ethernet connection.
8 Ports Ethernet Switch
This section displays the connection status of the Router’s eight Ethernet ports.
Clicking on a connection’s “Action” icon (in the column on the right) generates
the “Port VLANs” screen, where ingress and egress policies can be edited.
