Ethernet Port Numbering
On the back of a Linksys WRT54GL router, the Ethernet ports appear in this order:
| WAN | 1 | 2 | 3 | 4 |
Internally, the Ethernet ports are indexed in this order:
| 4 | 3 | 2 | 1 | 0 |
CFE and OpenWRT VLAN Configuration
In order to use the Linksys WRT54GL routers for complex routing purposes, both CFE and the operating system burned into Flash must be modified to separate the four LAN ports into their own network interfaces.
By default, the four LAN ports (0-3) are part of the same VLAN in CFE. (Port 5 is internal to the CPU.)
CFE> nvram get vlan0ports 3 2 1 0 5* *** command status = 0
This needs to be changed so that only one LAN port is in the VLAN. Select an appropriate port number based on the diagram above. The port that remains in the VLAN should be the one connected to the Xinu server.
CFE> nvram set vlan0ports="0 5*" *** command status = 0
The network configuration on OpenWRT must also be changed.
root@OpenWrt:/# vi /etc/config/network
The file will originally contain this section.
#### VLAN configuration
config switch eth0
option vlan0 "0 1 2 3 5*"
option vlan1 "4 5"
It should be changed to look like this where the port in vlan0 is the one connected to the Xinu server.
#### VLAN configuration
config switch eth0
option vlan0 "0 5*"
option vlan1 "4 5"
