Hi!
I installed Kamikaze 7.09 yesterday on a Netgear WGT634U. Most things work fine, but the not the WAN port.

tcpdump'ing shows that arp requests for the ISP gateway goes out on eth0.1 (WAN), but replies comes back on eth0.0 (LAN). This should indicate that something's up with the VLAN right?

VLAN is unmodified from the original config:

/etc/config/etwork:

#### VLAN configuration
config switch eth0
        option vlan0    "0 1 2 3 5*"
        option vlan1    "4 5"


#### Loopback configuration
config interface loopback
        option ifname   "lo"
        option proto    static
        option ipaddr   127.0.0.1
        option netmask  255.0.0.0


#### LAN configuration
config interface lan
        option type     bridge
        option ifname   "eth0.0"
        option proto    static
        option ipaddr   192.168.33.254
        option netmask  255.255.255.0


#### WAN configuration
config interface        wan
        option ifname   "eth0.1"
        option proto    static
        option ipaddr   my.static.isp.address
        option netmask  255.255.255.0
        option gateway the.isp.gateway.address

I'm connected to my ISP with a bridged ADSL modem and have a static IP address.

Any ideas?

Please ignore the above post. My ISP apparenly has some insane mac address filtering turned on. By setting the MAC address on the eth0.1 (WAN) interface to the same MAC address as my NIC I got things working smile

Sorry for the noise...

The discussion might have continued from here.
