Inbound Service Help
You can use this screen to define a new Inbound Firewall rule, or edit an existing rule.
Firewall rules can be used to block or allow specific traffic. This feature is for Advanced Administrators only! Incorrect configuration will cause serious problems.
Service
Select the desired Service. This determines which packets are covered by this rule. If necessary, you can define a new Service on the "Services" screen, by defining the protocols and port numbers used by the Service.
Action
Select the desired action for packets covered by this rule:
- ALLOW always
- ALLOW by schedule, otherwise Block
- BLOCK always
- BLOCK by schedule, otherwise Allow
Note:
- Any inbound traffic which is not allowed by 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.
WAN Users
These settings determine which packets are covered by the rule, based on their source (WAN) IP address.
Select the desired option:
- Any All IP addresses are covered by this 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 rule are logged. Select the desired action.
- Always - always log traffic considered by this rule, whether it matches or not. (This is useful when debugging your rules.)
- Never - never log traffic considered by this rule, whether it matches or not.
- Match - Log traffic only it matches this rule. (The action is determined by this rule.)
- Not Match - Log traffic which is considered by this rule, but does not match (The action is NOT determined by this rule.)
