Features

  • Intel IXP425 based (533MHz)
  • 2 WAN interfaces:
  • WAN1 is Realtek RTL8110s (theorically gigabit capable, but connected to a 10/100 Mbps transformer)
  • WAN2 is IXP425 NPE-C (10/100 Mbps)
  • 9 ports switch: Broadcom BCM5380MKPB (8 x 10/100 Mbps + 1 x 1Gbps), connected to IXP425 NPE-B MAC
  • up to 200 ipsec VPN (source: Netgear)
  • 2 hardware versions:

| | v1 | v2 | 

| Flash | 16MB | 32MB | 
| RAM | 32MB | 64MB | 
* Redboot bootloader

Work in progress

I did some patches to run OpenWRT in this box Not working / to do:

  • BCM5380 switch works standalone only, it is not usable as a network interface in linux at this time

The switch is fully working in Redboot, but we loose the MII connection when loading linux. 

 It seems that the mode of the switch MAC that is connected to the processor changes from "Reverse MII" to "Standard MAC/PHY" when loading linux.
 Then, the NPE driver always says "MII read failed" when the interface is up.
 * Nitrox Cavium encryption accelerator chip doesn't work as its driver is closed source
