IP Addresses and Routing
This table allows you to assign IP information for the LAN and WAN
ports separately. If you are using DHCP, the values for the LAN port will
be filled in automatically and any changes made will not affect the setup.
If Ethernet Bridging is enabled, the WAN port will use the same settings
as the LAN port, and any changes will not affect the setup for that port.
Adjusting the setting for the WAN port allows you greater control over
how the SVxx54DX4I is configured for access from outside the local
network, particularly if a firewall or proxy is in use.
Domain Name Server (optional)
This section allows you to specify DNS servers and the default DNS
domain suffix in use on the network. If DHCP is enabled, some of these
values may be supplied automatically.
Clicking the Commit button applies any changes made on this page,
but leaves the old settings active until the next time the unit restarts.
Clicking Make changes effective now applies the changes and restarts
SVxx54DX4I so the new settings take effect immediately.
Ethernet Address (MAC Address)
This is the Ethernet hardware address of the SVxx54DX4I’s LAN/
WAN port. This number is assigned as a factory default, and cannot be
changed. You may need this number to configure your DHCP server.
Ethernet Bridging
When Ethernet Bridging is enabled, the two Ethernet ports are virtually
connected inside the SVxx54DX4I. Packets arriving on either port
that are not meant for it will be forwarded out to the other port, when
appropriate. IEEE-802.1d (Spanning Tree Protocol) is implemented to
avoid broadcast storms and to determine the topology of the network.
You may connect both the WAN and LAN ports to the same logical
network through redundant Ethernet switches. If one switch fails, the
other will be used. When bridging is enabled, both ports share the same
configuration (DHCP or static IP addresses) and the WAN port may not
be separately configured. Using DHCP with Bridging increases boot
