 | LABEL | DESCRIPTION | 
| 
 | Symmetric | Select this option to enable symmetric NAT on this connection. | 
| 
 | 
 | This field is available only when you select Active NAT. | 
| 
 | 
 | 
 | 
| 
 | Fullcone | Select this option to enable full cone NAT on this connection. | 
| 
 | 
 | This field is available only when you select Active NAT. | 
| 
 | 
 | 
 | 
| 
 | VLAN | This section is available in this screen only when you select Bridge in | 
|

 | the Mode field. | 
| 
 | 
 | 
 | 
| 
 | VLAN Active | Select this option to enable VLAN multiplexing of multiple protocols | 
| 
 | 
 | over a single virtual circuit. You need to assign a VLAN ID and priority | 
| 
 | 
 | level to traffic through each WAN connection. All WAN connections | 
| 
 | 
 | share one MAC address. This allows the backbone switch to classify | 
| 
 | 
 | and service traffic based on the VLAN tag, instead of the MAC address. | 
| 
 | 
 | Otherwise, disable VLAN multiplexing and each WAN connection has | 
| 
 | 
 | its own MAC address. | 
| 
 | 
 | Note: This field is only configurable for the first WAN connection. | 
| 
 | 
 | When you change the setting here, all existing WAN | 
| 
 | 
 | connections will be removed except for the first WAN | 
| 
 | 
 | connection. | 
| 
 | 
 |

 | VLAN ID | Enter a VLAN ID number for traffic that goes through this connection. | 
| 
 | 
 | 
 | 
| 
 | Priority | Enter a priority level for traffic that goes through this connection. |
