Configuring Ethernet Settings
This section describes how to configure Ethernet settings on each port of the SonicWALL appliance(s).
The Ethernet Settings screen is only available on SonicWALL 6.x.x.x firmware versions and SonicOS Standard firmware versions.
To configure Ethernet settings, complete the following steps:
1
Expand the Network tree and click Ethernet. The Ethernet page displays.
 
2
Select from the following WAN Link Settings:
•
To configure the WAN link to automatically negotiate Ethernet settings, select Auto Negotiate.
•
To specify WAN link settings, select Force and select the speed and duplex settings.
3
Select from the following OPT Link Settings:
•
To configure the OPT to automatically negotiate Ethernet settings, select Auto Negotiate.
•
To specify OPT link settings, select Force and select the speed and duplex settings.
4
Select from the following LAN Link Settings:
•
To configure the LAN link to automatically negotiate Ethernet settings, select Auto Negotiate.
•
To specify LAN link settings, select Force and select the speed and duplex settings.
5
If you are managing the Ethernet connection from the LAN (WorkPort) side of your network, select Proxy Management Workstation Ethernet Address on WAN. The SonicWALL appliance will take the Ethernet address of the computer that is managing the SonicWALL appliance and will proxy the address on the WAN port of the SonicWALL. If you are not managing the SonicWALL appliance from the LAN side of your network, the firmware looks for a random computer on the LAN which can be a lengthy search process.
6
To limit the size of packets sent over the Ethernet WAN interface, select Fragment Outbound Packets Larger than the WAN MTU and enter the maximum size in the WAN MTU field. If the maximum transmission unit (MTU) size is too large for a remote router, it might require more transmissions. If the packet size is too small, this could result in more packet header overhead and more acknowledgements that have to be processed. The default size is 1,500 MTU.
7
To enable bandwidth management, select Enable and enter the bandwidth of the connection in the Available Bandwidth field.
8
When you are finished, click Update. The settings are changed for each selected SonicWALL appliance. To clear all screen settings and start over, click Reset.
