Routing tags are used on the device in order to evaluate criteria relevant to the selection of the target route in addition to the IP address. In general, routing tags are added to the data packets using special firewall rules. However, in some cases, it is desirable to assign the tags directly.
- Routing tags for VPN connections
The VPN name list can be used to enter the routing tag for every VPN connection. The routing tag is used in order to determine the route to the remote gateway (default '0').
In addition, every gateway can be assigned a specific routing tag in the gateway table. The tag 0 has a special function in this table: If the tag is set at 0 on a gateway, then the tag from the VPN name list table is used.
The VPN routing tag parameters can be found under Setup/VPN/VPN Peers or Setup/VPN/Additional Gateways and under LANconfig in the configuration section 'VPN' on the 'General' tab by clicking on 'Connection List' and 'Further remote gateways' in the list.
- Routing tags for PPTP connections
In the PPTP table, a routing tag can be entered in addition to the IP address of the PPTP server. Using this routing tag, two or more DSL modems that use a single IP address can be operated on different DSL ports.
| Peer | IP address | Rtg tag | Port | SH-Time |
|---|---|---|---|---|
| PEER01 | 10.0.0.138 | 1 | 1723 | 9999 |
| PEER02 | 10.0.0.138 | 2 | 1723 | 9999 |
In the IP routing table, two appropriately tagged routes are required:
| IP address | IP-Netmask | Rtg tag | Peer-or-IP | Distance | Masking |
|---|---|---|---|---|---|
| 10.0.0.138 | 255,255,255,255 | 2 | PEER02-PPTP | 0 | No |
| 10.0.0.138 | 255,255,255,255 | 1 | PEER01-PPTP | 0 | No |
| 192.168.0.0 | 255.255.0.0 | 0 | 0.0.0.0 | 0 | No |
| 172.16.0.0 | 255.240.0.0 | 0 | 0.0.0.0 | 0 | No |
| 10.0.0.0 | 255.0.0.0 | 0 | 0.0.0.0 | 0 | No |
| 224.0.0.0 | 224.0.0.0 | 0 | 0.0.0.0 | 0 | No |
| 255,255,255,255 | 0.0.0.0 | 0 | PEER-LB | 0 | Yes |
Using these settings and the corresponding entry in the load balancing table, load balancing can be performed that would also work in Austria.
| Peer | Bundle-Peer-1 | Bundle-Peer-2 | Bundle-Peer-3 |
|---|---|---|---|
| PEER-LB | PEER01 | PEER02 |
