Routing Table
Routing Table Overview
Routing is based on the destination address only and the Zyxel Device takes the shortest path to forward a packet.
Routing Table
The table below shows IPv4 and IPv6 routing information. The IPv4 subnet mask is ‘255.255.255.255’ for a host destination and ‘0.0.0.0’ for the default route. The gateway address is written as ‘*’(IPv4)/‘::’(IPv6) if none is set.

The following table describes the labels in this screen.
label | Description |
|---|---|
Destination | This indicates the destination IPv4 address or IPv6 address and prefix of this route. |
Gateway | This indicates the IPv4 address or IPv6 address of the gateway that helps forward this route’s traffic. |
Subnet Mask | This indicates the destination subnet mask of the IPv4 route. |
Flag | This indicates the route status. U–Up: The route is up. !–Reject: The route is blocked and will force a route lookup to fail. G–Gateway: The route uses a gateway to forward traffic. H–Host: The target of the route is a host. R–Reinstate: The route is reinstated for dynamic routing. D–Dynamic (redirect): The route is dynamically installed by a routing daemon or redirect. M–Modified (redirect): The route is modified from a routing daemon or redirect. |
Metric | The metric represents the "cost of transmission." A router determines the best route for transmission by choosing a path with the lowest "cost." The smaller the number, the lower the "cost." |
Interface | This indicates the name of the interface through which the route is forwarded. • brx indicates a LAN interface where x can be 0 – 3 to represent LAN1 to LAN4 respectively. • ethx indicates an Ethernet WAN interface using IPoE or in bridge mode. • ppp0 indicates a WAN interface using PPPoE. • wlx indicates a wireless interface where x can be 0 – 1. |
