I've got a WBMR-HP-G300H Buffalo Airstation router on which I've installed the lates OpenWRT software.

All is working well (ADSL, WIFI etc) except for one niggle. I can't communicate between lan ports. i.e. if I have one computer connected on lan port 1 and I try to ping another computer on lan port 2 then I get "destination unreachable".

I can ping both computers from the router itself and can also ping each computer from a seperate laptop connected wirelessly. All computers are in the same subnet range (10.0.0.?/24).

I suspect that I may need to configure a vlan on the switch but everytime I try and do this with various google'ed configuration I keep freezing out all lan-ports and I have to revert back using a wirelessly connected laptop.

Here's my /etc/config/network:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config interface 'lan'
        option type 'bridge'
        option proto 'static'
        option netmask '255.255.255.0'
        option ipaddr '10.0.0.1'
        option _orig_ifname 'eth0 wlan0'
        option _orig_bridge 'true'
        option ifname 'eth0'

config adsl-device 'adsl'
        option fwannex 'a'
        option annex 'a2p'

config interface 'wan'
        option _orig_ifname 'nas0'
        option _orig_bridge 'false'
        option proto 'pppoa'
        option encaps 'vc'
        option atmdev '0'
        option vci '38'
        option vpi '0'
        option username '?????????????'
        option password '??????????????'

Any help would be warmly received.

Here's some more config stuff.
