8.6.9 Routing
Description
The built-in router supports routing over the WAN–LAN boundary using IPv4. This PBX supports static routing
only. It does not support dynamic routing through RIP (Routing Information Protocol).
Static Routing
•
Up to 64 entries can be entered.
•
To determine how packets are routed, a static routing destination can be specified for each entry.
•
You can specify either "next hop (gateway address)" or "PPPoE session ID" for the routing destination.
•
You can specify the default route (the route specified packets that do not match the routing information).
•
You can specify the distance for each entry.
Dynamic Routing
•
Not supported.
Conditions
•
This feature conforms to RFC 1812: Requirements for IP Version 4 Routers.
•
For details about routing rules, consult the network administrator.

8.6.10 Firewall
Description
The built-in router includes a firewall for inspecting packets at the WAN–LAN boundary and rejecting
unauthorised packets. The firewall can also sense unauthorised access and DoS attacks and take appropriate
measures. This feature applies only to packets routed via IP.
This feature does not apply to data routed through a tunnel, such as with IPsec.
Conditions
•
Filter priority
If multiple security settings are enabled, such as Packet Filtering, SPI, and DoS Protection, some filter
settings may conflict with one another. To avoid this, the following priorities are applied to the filters. In the
table, priority 1 has the highest priority, and priority 13 has the lowest priority.
