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.

Click on “Add” to enter the configuration page to add your own rule(s). Some games,

video conferencing, remote access applications and other software might require that

specific ports in the Router's firewall be opened for access. You can configure the port

settings from this screen by selecting an existing application or creating your own (Custom

application) and click “Save/Apply” to add it.

To delete the configured rule(s), check the “Remove” box of the specific rule(s) and click

on “Remove”.

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.

Enter the destination network address, subnet mask, gateway AND/OR available WAN

interface, then click “Save/Apply” to add the entry to the routing table.

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”.
