ProSafe VPN Firewall 200 FVX538 Reference Manual 3. Build your list of Source MAC Addresses to be block by entering the first MAC address in the MAC Address field in the form xx:xx:xx:xx:xx:xx where x is a numeric (0 to 9) or an alphabet between and a and f (inclusive), for example: 00:e0:4c:69:0a: 4. Click Add. The Mac Address will be added to the Available MAC Addresses to be Blocked table. (You can edit the MAC address by clicking Edit in the Action column adjacent to the MAC Address.) 5. Click Reset to cancel a MAC address entry before adding it to the table. 6. Click Apply to save your settings. To remove an entry from the table, select the MAC address entry and click Delete. To select all the list of MAC addresses, click Select All. A checkmark will appear in the box to the left of each MAC address in the Available MAC Addresses to be Blocked table. Port Triggering Port triggering allows some applications running on a LAN network to be available to external applications that would otherwise be partially blocked by the firewall. Using this feature requires that you know the port numbers used by the Application. Once configured, Port Triggering operates as follows: 1. A PC makes an outgoing connection using a port number defined in the Port Triggering table. 2. The VPN firewall records this connection, opens the additional INCOMING port or ports associated with this entry in the Port Triggering table, and associates them with the PC. 3. The remote system receives the PCs request and responds using the different port numbers that you have now opened. 4. The VPN firewall matches the response to the previous request, and forwards the response to the PC. Without Port Triggering, this response would be treated as a new connection request rather than a response. As such, it would be handled in accordance with the Port Forwarding rules: • Only one PC can use a Port Triggering application at any time. 4-28 Firewall Protection and Content Filtering v1.0, August 2006

Firewall Protection and Content Filtering

v1.0, August 2006

Build your list of Source MAC Addresses to be block by entering the first MAC address in the

MAC Address

field in the form xx:xx:xx:xx:xx:xx where x is a numeric (0 to 9) or an

alphabet between and a and f (inclusive), for example: 00:e0:4c:69:0a:

Click

Add.

The Mac Address will be added to the

Available MAC Addresses to be Blocked

table. (You can edit the MAC address by clicking

Edit

in the Action column adjacent to the

MAC Address.)

Click

Reset

to cancel a MAC address entry before adding it to the table.

Click

Apply

to save your settings.

To remove an entry from the table, select the MAC address entry and click

Delete

To select all the list of MAC addresses, click

Select All.

A checkmark will appear in the box to the

left of each MAC address in the

Available MAC Addresses to be Blocked

table

Port Triggering

Port triggering allows some applications running on a LAN network to be available to external

applications that would otherwise be partially blocked by the firewall. Using this feature requires

that you know the port numbers used by the Application.

Once configured, Port Triggering operates as follows:

A PC makes an outgoing connection using a port number defined in the Port Triggering table.

The VPN firewall records this connection, opens the additional INCOMING port or ports

associated with this entry in the Port Triggering table, and associates them with the PC.

The remote system receives the PCs request and responds using the different port numbers that

you have now opened.

The VPN firewall matches the response to the previous request, and forwards the response to

the PC.

Without Port Triggering, this response would be treated as a new connection request rather than a

response. As such, it would be handled in accordance with the Port Forwarding rules:

•

Only one PC can use a Port Triggering application at any time.
