Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V Note: Any inbound traffic which is not allowed by firewall rules you create will be blocked by the Default rule. BLOCK rules are only useful if the traffic is already covered by an ALLOW rule. (That is, you wish to block a sub-set of traffic which is currently allowed by another rule.) To define the Schedule used in these selections, use the "Schedule" screen. • LAN Server: Enter the IP address of the PC or Server on your LAN which will receive the inbound traffic covered by this rule.This field is disabled if action selected is "Block Always". • Forwarding Port - If you select 'Same as Incoming port' then all incoming traffic on specified Service is forwarded to LAN server without modifying Destination Port. - If you select 'Forward to another port range' then all incoming traffic received on the Service port (or range of ports) is forwarded to this port or range of ports of the LAN Server. - This field is disabled if action selected is "Block Always". - If you want to forward the traffic to a single port then enter port value in start port and leave finish port empty. - If you want to forward the traffic to range of ports then enter non zero value in finish port and make sure that service record attached to this rule has range of ports and range is equal to that of forwarding ports. - For example if you select Service as HTTP (TCP/80), LAN Server IP address as 192.168.15.10 and Forwarding port as 8080 then all traffic coming from internet on - TCP/80 (HTTP) to this Router is redirected to TCP/8080 port of 192.168.15.10 • WAN Users: These settings determine which packets are covered by the firewall rule, based on their source (WAN) IP address. Select the desired option: - Any All IP addresses are covered by this firewall rule. - Address range If this option is selected, you must enter the "Start" and "Finish" fields. - Single address Enter the required address in the "Start" fields. • Log: This determines whether packets covered by this firewall rule are logged. Select the desired action. - Never - never log traffic considered by this firewall rule, whether it matches or not. - Match - Log traffic only it matches this firewall rule. (The action is determined by this firewall rule.) Content Filtering 4-7 202-10051-01, March 2005

Note

Any inbound traffic which is not allowed by firewall rules you create will be blocked by the

Default rule.

BLOCK rules are only useful if the traffic is already covered by an ALLOW rule. (That is, you

wish to block a sub-set of traffic which is currently allowed by another rule.)

To define the Schedule used in these selections, use the "Schedule" screen.

•

LAN Server: Enter the IP address of the PC or Server on your LAN which will receive the

inbound traffic covered by this rule.This field is disabled if action selected is "Block Always".

•

Forwarding Port

–

If you select 'Same as Incoming port' then all incoming traffic on specified Service is

forwarded to LAN server without modifying Destination Port.

–

If you select 'Forward to another port range' then all incoming traffic received on the

Service port (or range of ports) is forwarded to this port or range of ports of the LAN

Server.

–

This field is disabled if action selected is "Block Always".

–

If you want to forward the traffic to a single port then enter port value in start port and

leave finish port empty.

–

If you want to forward the traffic to range of ports then enter non zero value in finish port

and make sure that service record attached to this rule has range of ports and range is equal

to that of forwarding ports.

–

For example if you select Service as HTTP (TCP/80), LAN Server IP address as

192.168.15.10 and Forwarding port as 8080 then all traffic coming from internet on

–

TCP/80 (HTTP) to this Router is redirected to TCP/8080 port of 192.168.15.10

•

WAN Users: These settings determine which packets are covered by the firewall rule, based on

their source (WAN) IP address. Select the desired option:

–

Any

All IP addresses are covered by this firewall rule.

–

Address range

If this option is selected, you must enter the "Start" and "Finish" fields.

–

Single address

Enter the required address in the "Start" fields.

•

Log: This determines whether packets covered by this firewall rule are logged. Select the

desired action.

–

Never - never log traffic considered by this firewall rule, whether it matches or not.

–

Match - Log traffic only it matches this firewall rule. (The action is determined by this

firewall rule.)
