Port Triggering
Some applications require that specific ports in the Router's firewall be opened for access
by the remote parties. Port Trigger dynamically opens up the “Open Ports” in the firewall
when an application on the LAN initiates a TCP/UDP connection to a remote party using
the “Triggering Ports”. The Router allows the remote party from the WAN side to establish
new connections back to the application on the LAN side using the “Open Ports”. A
maximum of 32 entries can be configured.

5.4 - Routing
There are three routing related settings:
Routing – Default Gateway
If the “Enable Automatic Assigned Default Gateway” checkbox is selected, the
M404/M405 will accept the first received default gateway assignment from one of the
PPPoA, PPPoE or MER/DHCP enabled PVC(s). If the checkbox is not selected, enter the
static default gateway AND/OR a WAN interface. Click the “Save/Apply” button to save it.
NOTE:
If changing the “Enable Automatic Assigned Default Gateway” from
unselected to selected, you must reboot your M404/M405 to activate the
automatically assigned default gateway.

Routing – RIP
The Routing Information Protocol (RIP) is designed for exchanging routing information
within a small to medium-size network.
Figure 34. Advanced Setup – Routing – RIP
To configure an individual interface, select the desired RIP version and operation:
RIP Version 1
: Class-based IP network.
RIP Version
2
: Classless IP network.
Operation Active
: Broadcast and listen to other RIP enabled devices.
Operation
Passive
: Listen only.
Place a check in the “Enabled” checkbox next to the interface to complete the
configuration. Click the “Save/Apply” button to save the configuration. To start/stop RIP
for the M404/M405, select the “Enabled/Disabled” radio button for “
Global RIP Mode”.
