I am having issues my WAN interface on a RT210 board (broadcom 4710).  I could not get udhcpc to get an IP, so I tried static.  Looking at the packets I see that nobody is responding to my arp requests at all.  I have a got feeling its a vlan issue but I'm not that familiar with the openwrt vlan configuration. 

From looking at my network configuration via ifconfig and /etc/config/network, I don't appear to be using VLANS at all.  Ifconfig shows 4 interfaces - br-lan, eth0, eth1, lo - all are UP.  The lan side (br-lan and eth0) work fine, only the wan side (eth1) has issues.  When I tcpdump the wan (eth1) I see network traffic from other machines on my network in addition to my arp requests (when trying static ip) and dhcp requests (when configured for dhcp) - I just never get responses, as if I am being completely ignored on the network.

Any ideas?  thoughts?

Keep in mind I am rather new to OpenWRT so please bear with..
