8.2 System Log 
This function allows a system log to be kept and viewed upon request.   
Follow the steps below to configure, enable, and view the system log. 
STEP 1:  Click Configure System Log, as shown below (circled in Red). 
STEP 2:  Select desired options and click Apply/Save. 
Consult the table below for detailed descriptions of each system log option. 
Option  Description 
Log   Indicates whether the system is currently recording events.  The user 
can enable or disable event logging.  By default, it is disabled.  To 
enable it, select the Enable radio button and then click Apply/Save.  

120
Option  Description 
Log 
Level  Allows you to configure the event level and filter out unwanted events 
below this level.  The events ranging from the highest critical level 
“Emergency” down to this configured level will be recorded to the log 
buffer on the VR-3033 SDRAM.  When the log buffer is full, the newer 
event will wrap up to the top of the log buffer and overwrite the old event. 
By default, the log level is “Debugging”, which is the lowest critical level. 
The log levels are defined as follows: 
•  Emergency = system is unusable 
•  Alert = action must be taken immediately 
•  Critical = critical conditions 
•  Error = Error conditions 
•  Warning = normal but significant condition 
•  Notice= normal but insignificant condition 
•  Informational= provides information for reference 
•  Debugging = debug-level messages 
Emergency is the most serious event level, whereas Debugging is the 
least important.   For instance, if the log level is set to Debugging, all the 
events from the lowest Debugging level to the most critical level 
Emergency level will be recorded.  If the log level is set to Error, only 
Error and the level above will be logged. 
Display 
Level  Allows the user to select the logged events and displays on the View 
System Log window for events of this level and above to the highest 
Emergency level. 
Mode  Allows you to specify whether events should be stored in the local 
memory, or be sent to a remote system log server, or both 
simultaneously.  If remote mode is selected, view system log will not be 
able to display events saved in the remote system log server.   
When either Remote mode or Both mode is configured, the WEB UI will 
prompt the user to enter the Server IP address and Server UDP port. 
STEP 3:  Click View System Log.  The results are displayed as follows.

Appendix A - Firewall 
STATEFUL PACKET INSPECTION 
Refers to an architecture, where the firewall keeps track of packets on each 
connection traversing all its interfaces and makes sure they are valid. This is in 
contrast to static packet filtering which only examines a packet based on the 
information in the packet header. 
DENIAL OF SERVICE ATTACK 
Is an incident in which a user or organization is deprived of the services of a 
resource they would normally expect to have. Various DoS attacks the device can 
withstand are ARP Attack, Ping Attack, Ping of Death, Land, SYN Attack, Smurf 
Attack, and Tear Drop. 
TCP/IP/PORT/INTERFACE FILTER 
These rules help in the filtering of traffic at the Network layer (i.e. Layer 3). 
When a Routing interface is created, Enable Firewall must be checked. 
Navigate to Advanced Setup  Security  IP Filtering. 
OUTGOING IP FILTER 
Helps in setting rules to DROP packets from the LAN interface. By default, if the 
Firewall is Enabled, all IP traffic from the LAN is allowed. By setting up one or more 
filters, specific packet types coming from the LAN can be dropped. 
    Example 1:  Filter Name      : Out_Filter1 
Protocol    : TCP 
Source IP address    : 192.168.1.45 
Source Subnet Mask  : 255.255.255.0 
Source Port      : 80 
Dest. IP Address    : NA 
Dest. Subnet Mask   : NA 
Dest. Port      : NA 
This filter will Drop all TCP packets coming from the LAN with IP 
Address/Subnet Mask of 192.168.1.45/24 having a source port of 80 
irrespective of the destination. All other packets will be Accepted. 
Example 2:  Filter Name      : Out_Filter2 
Protocol    : UDP 
Source IP Address   : 192.168.1.45 
Source Subnet Mask  : 255.255.255.0 
Source Port      : 5060:6060 
Dest. IP Address    : 172.16.13.4 
Dest. Subnet Mask   : 255.255.255.0 
Dest. Port      : 6060:7070 
This filter will drop all UDP packets coming from the LAN with IP Address / 
Subnet Mask of 192.168.1.45/24 and a source port range of 5060 to 6060, 
destined to 172.16.13.4/24 and a destination port range of 6060 to 7070. 
INCOMING IP FILTER 
Helps in setting rules to Allow or Deny packets from the WAN interface. By default, 
all incoming IP traffic from the WAN is Blocked, if the Firewall is Enabled. By setting 
up one or more filters, specific packet types coming from the WAN can be Accepted. 

134
 Example 1:  Filter Name      : In_Filter1 
Protocol    : TCP 
Policy    : Allow 
Source IP Address   : 210.168.219.45 
Source Subnet Mask  : 255.255.0.0 
Source Port      : 80 
Dest. IP Address    : NA 
Dest. Subnet Mask   : NA 
Dest. Port      : NA 
Selected WAN interface : br0 
This filter will ACCEPT all TCP packets coming from WAN interface “br0” with IP 
Address/Subnet Mask 210.168.219.45/16 with a source port of 80, irrespective 
of the destination. All other incoming packets on this interface are DROPPED. 
Example 2:  Filter Name      : In_Filter2 
Protocol    : UDP 
Policy    : Allow 
Source IP Address   : 210.168.219.45 
Source Subnet Mask  : 255.255.0.0 
Source Port      : 5060:6060 
Dest. IP Address    : 192.168.1.45 
Dest. Sub. Mask    : 255.255.255.0 
Dest. Port      : 6060:7070 
Selected WAN interface : br0 
This rule will ACCEPT all UDP packets coming from WAN interface “br0” with IP 
Address/Subnet Mask 210.168.219.45/16 and a source port in the range of 
5060 to 6060, destined to 192.168.1.45/24 and a destination port in the range 
of 6060 to 7070. All other incoming packets on this interface are DROPPED.  
MAC LAYER FILTER 
These rules help in the filtering of Layer 2 traffic. MAC Filtering is only effective in 
Bridge mode. After a Bridge mode connection is created, navigate to Advanced 
Setup  Security  MAC Filtering in the WUI. 
Example 1:  Global Policy      : Forwarded 
Protocol Type      : PPPoE 
Dest. MAC Address   : 00:12:34:56:78:90 
Source MAC Address  : NA 
Src. Interface     : eth1 
Dest. Interface    : eth2 
Addition of this rule drops all PPPoE frames going from eth1 to eth2 with a 
Destination MAC Address of 00:12:34:56:78:90 irrespective of its Source MAC 
Address. All other frames on this interface are forwarded. 
Example 2:  Global Policy      : Blocked 
Protocol Type      : PPPoE 
Dest. MAC Address   : 00:12:34:56:78:90 
Source MAC Address  : 00:34:12:78:90:56 
Src. Interface     : eth1 
Dest. Interface    : eth2 
Addition of this rule forwards all PPPoE frames going from eth1 to eth2 with a 
Destination MAC Address of 00:12:34:56:78 and Source MAC Address of 
00:34:12:78:90:56. All other frames on this interface are dropped. 

135
DAYTIME PARENTAL CONTROL 
This feature restricts access of a selected LAN device to an outside Network through 
the VR-3033, as per chosen days of the week and the chosen times. 
Example:  User Name      : FilterJohn 
Browser's MAC Address : 00:25:46:78:63:21 
Days of the Week    : Mon, Wed, Fri 
Start Blocking Time  : 14:00 
End Blocking Time   : 18:00 
With this rule, a LAN device with MAC Address of 00:25:46:78:63:21 will have 
no access to the WAN on Mondays, Wednesdays, and Fridays, from 2pm to 6pm. 
On all other days and times, this device will have access to the outside 
Network.

STEP 1:  Select the PPP over Ethernet radio button and click Next. You can also 
enable IPv6 by ticking the checkbox  at the bottom of this screen. 
STEP 2:  On the next screen, enter the PPP settings as provided by your ISP.  
Click Next to continue or click Back to return to the previous step. 

157
The settings shown above are described below. 
PPP SETTINGS 
The PPP Username, PPP password and the PPPoE Service Name entries are 
dependent on the particular requirements of the ISP.  The user name can be a 
maximum of 256 characters and the password a maximum of 32 characters in 
length. For Authentication Method, choose from AUTO, PAP, CHAP, and MSCHAP. 
ENABLE FULLCONE NAT 
This option becomes available when NAT is enabled. Known as one-to-one NAT, all 
requests from the same internal IP address and port are mapped to the same 
external IP address and port. An external host can send a packet to the internal host, 
by sending a packet to the mapped external address. 

158
DIAL ON DEMAND 
The VR-3033 can be configured to disconnect if there is no activity for a period of 
time by selecting the Dial on demand checkbox .  You must also enter an 
inactivity timeout period in the range of 1 to 4320 minutes.   
PPP IP EXTENSION 
The PPP IP Extension is a special feature deployed by some service providers.  
Unless your service provider specifically requires this setup, do not select it. 
  PPP IP Extension does the following: 
•  Allows only one PC on the LAN. 
•  Disables NAT and Firewall. 
•  The device becomes the default gateway and DNS server to the PC 
through DHCP using the LAN interface IP address. 
•  The device extends the IP subnet at the remote service provider to the 
LAN PC.  i.e. the PC becomes a host belonging to the same IP subnet. 
•  The device bridges the IP packets between WAN and LAN ports, unless 
the packet is addressed to the device’s LAN IP address. 
•  The public IP address assigned by the remote side using the PPP/IPCP 
protocol is actually not used on the WAN PPP interface.  Instead, it is 
forwarded to the PC LAN interface through DHCP.  Only one PC on the 
LAN can be connected to the remote, since the DHCP server within the 
device has only a single IP address to assign to a LAN device. 
ENABLE NAT 
If the LAN is configured with a private IP address, the user should select this 
checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot.   
On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN 
side is using a public IP), this checkbox  should not be selected to free up system 
resources for better performance.   
ENABLE FIREWALL 
If this checkbox  is selected, the Security submenu will be displayed on the 
Advanced Setup menu after reboot. If firewall is not necessary, this checkbox  
should not be selected to free up system resources for better performance.   
USE STATIC IPv4 ADDRESS 
Unless your service provider specially requires it, do not select this checkbox .  If 
selected, enter the static IP address in the IPv4 Address field.  
Don’t forget to adjust the IP configuration to Static IP Mode as described in section 
3.2 IP Configuration. 
FIXED MTU 
Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which 
the layer can pass onwards. This value is 1500 for PPPoA. 
ENABLE PPP DEBUG MODE 
When this option is selected, the system will put more PPP connection information 
into the system log.  This is for debugging errors and not for normal usage. 

159
BRIDGE PPPOE FRAMES BETWEEN WAN AND LOCAL PORTS  
(This option is hidden when PPP IP Extension is enabled) 
When Enabled, this creates local PPPoE connections to the WAN side. Enable this 
option only if all LAN-side devices are running PPPoE clients, otherwise disable it.  
The VR-3033 supports pass-through PPPoE sessions from the LAN side while 
simultaneously running a PPPoE client from non-PPPoE LAN devices.  
ENABLE IGMP MULTICAST PROXY 
Tick the checkbox  to enable Internet Group Membership Protocol (IGMP) 
multicast. This protocol is used by IPv4 hosts to report their multicast group 
memberships to any neighboring multicast routers. 
Enable IGMP Multicast Source 
Enable the WAN interface to be used as IGMP multicast source.  
STEP 3:  Choose an interface to be the default gateway. 
Click Next to continue or click Back to return to the previous step.

STEP 2:  The WAN IP settings screen provides access to the DHCP server settings.    
  You can select the Obtain an IP address automatically radio button to 
enable DHCP (use the DHCP Options only if necessary). However, if you 
prefer, you can instead use the Static IP address method to assign WAN 
IP address, Subnet Mask and Default Gateway manually. 

162
