Default: Auto
MTU
This field is for specifying the Maximum Transmission Unit value of the WAN connection. An
excessive MTU value can cause file downloads stall shortly after connected. You may
consult your ISP for the connection's MTU value. Default value is 1440.
MSS
This field is for specifying the Maximum Segment Size of the WAN connection.
When Auto is selected, MSS will be depended on the MTU value. When Custom is selected,
you may enter a value for MSS. This value will be announced to remote TCP servers for
maximum data that it can receive during the establishment of TCP connections.
Some Internet servers are unable to listen to MTU setting if ICMP is filtered by firewall
between the connections.
Normally, MSS equals to MTU minus 40. You are recommended to reduce the MSS only if
changing of the MTU value cannot effectively inform some remote servers to size down data
size.
Default: Auto
MAC Address
Clone
Some service providers (e.g. cable network) identify the client's MAC address and require
client to always use the same MAC address to connect to the network. If it is the case, you
may change the WAN interface's MAC address to the client PC's one by entering the PC's
MAC address to this field. If you are not sure, click the Default button to restore to the default
value.
VLAN
Check the box to assign a VLAN to the interface.
