you greater control over how the SV1110IPEXT 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.
Commit Network Changes
Clicking the
Commit
button applies any changes made on the page to the
configuration, but leaves the old settings active until the next time the unit
restarts. Clicking
Make changes effective now
applies the changes and restarts
the SV1110IPEXT so the new settings take effect immediately.
Ethernet Bridging
When Ethernet
bridging is enabled,
the two Ethernet
ports are virtually
connected inside the
SV1110IPEXT.
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 enable this feature so that the module can be inserted inline with the
host it monitors. This reduces the wiring and number of Ethernet ports required.
Alternatively, 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 time, because the 802.1d (STP) algorithm
must finish before the DHCP broadcast can go out. To change this setting, select
either
Enabled
or
Disabled
from the drop-down menu and click
Commit and
Apply
.
User accounts (add, delete and change passwords)
This menu will allow you to add accounts other than
admin
to the system. These
accounts will not have the authority to change settings, but can access the Web
interface and log in the VNC console. Selecting
Delete
permanently removes the
user from the system. If you enter values for a user that does not already exist
under
Edit User Details
, the system will create that user for you when you click
