Connect Automatically, as Required
This option just can act when ppp is not set to be always on line.Normally, this option should be
Enabled, so that an Internet connection will be made automatically, whenever Internet-bound traffic
is detected. If this causes high connection costs, you can disable this setting.
If disabled, you must connect manually, using the sub-screen accessed from the "Connection
Status" button on the Status screen.
If you have an "Always on" connection, this setting has no effect.
Disable Port Scan and DOS Protection - The Firewall protects your LAN against Port Scans and
Denial of Service (DOS) attacks. This should be disabled only in special circumstances.
Respond To Ping On Internet Port
If you want the VVG2000 to respond to a 'Ping' from the Internet, click this check box. This can be
used as a diagnostic tool. This can be a security problem. You shouldn't check this box unless you
have a specific reason to do so.
MTU Size
The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, or
1492 Bytes for PPPoE connections. For some ISPs you may need to reduce the MTU. But this is
rarely required, and should not be done unless you are sure it is necessary for your ISP connection.
DNS Server Configuration
If 'Enable Automatic Assigned DNS' checkbox is selected, this router will only accept the received
DNS assignment from one of the PPPoA, PPPoE or MER/DHCP enabled PVC(s) from WAN1
during the connection establishment. If the checkbox is not selected, enter the primary and optional
secondary DNS server IP addresses.
Routing -- Default Gateway
If Enable Automatic Assigned Default Gateway checkbox is selected, this router will only accept
the received default gateway assignment from one of the PPPoA, PPPoE or MER/DHCP enabled
PVC(s) from WAN1. If the checkbox is not selected, enter the static default gateway AND/OR a
WAN interface.
