Hi All,
I have 2 fonera router running openwrt and batman
wireless IP are 192.168.2.200 and 192.168.2.203
Routers have separete wifi and eth interfaces
Here it is openwrt network config file:
root@OpenWrt:~# cat /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 'ifname' 'eth0'
option 'type' 'bridge'
option 'proto' 'static'
option 'ifname' 'eth0'
option 'ipaddr' '192.168.0.203'
option 'netmask' '255.255.255.0'
option 'gateway' '192.168.0.1'
option 'dns' '192.168.0.1'
config 'interface' 'wifi'
option 'ifname' 'ath0'
option 'proto' 'static'
option 'ipaddr' '192.168.2.203'
option 'netmask' '255.255.255.0'
other router has br-lan 192.168.1.200 and 192.168.0.200
router 192.168.2.203 is connected to my ADSL modem (IP 192.168.0.1)
through ethernet port (br-lan in openwrt)
I would like to connect to internet (and at least to ADSL modem) but
something doesn't work...
I used this command on node 200:
root@OpenWrt:~# batmand ath0
I used this command on node 203:
root@OpenWrt:~# batmand -a 192.168.0.1/24 ath0
Interface activated: ath0
Using interface ath0 with address 192.168.2.203 and broadcast address
192.168.2.255

As you can see from node 200 I can ping node 203 (wireless interface
192.168.2.203 and wired interface 192.168.0.203), but I'm unable to go
through adsl modem (192.168.0.1)
But I can connect to adsl modem from node 203
Any Hints?
Thanks

On mesh router connected to ADSL:
batmand -g 1000 ath0
On other mesh router:

You can safely ignore the 169.254.x.x addresses. Batman uses that for its
internal tunneling mechanism which should not concern you.
Does your setup work now or not ?

The 0.3.1 is good but please don't use the 0.3-beta in a production
environment! The 0.3 contained several bugs thats why we had the 0.3.1
release. Consider upgrading to the latest stable release (0.3.1 at the
moment).

Any Hints?
sure: You are not announcing a default route.
On mesh router connected to ADSL:
batmand -g 1000 ath0
On other mesh router:
batmand -r 1 ath0
You have to NAT towards the internet on the gateway.

further; from GATEWAY batman node 200 (connected to wired lan and internet)
I can ping everything
So this means:
From the CLIENT batman node 203 (not connected to wired lan and internet)
I can ping wireless interface of the batman node connected to wired lan
I can ping br-lan wired interface of the batman node connected to wired
lan (so I think routing exist)
I CAN'T ping other nodes seen by br-lan wired interface of the batman
node connected to wired lan
I suspect the problem could be elsewhere batman, isn't it?

There is a bug in batmand in current 0.3.2 code, which occurs when you use HNA
(-a). We are currently working on it. You don't need to use -a to connect to
the internet in your case, however. But you have to set up simple NAT towards
the interface of the batman-gateway connected to the ADSL modem.
If that interface is eth0 the command would be:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

But I can connect to adsl modem from node 203
Solution was found today on irc.
Marco hadn't setup a NAT on the gateway node
as described in paragraph 4.2 " Why I can’t connect to the Internet after
setting the default gateway?" in
http://downloads.open-mesh.net/batman/misc/batmand_howto.pdf
A different solution was suggested by Simon to set the route to 192.168.2.x
nodes on 192.168.0.x nodes over the gateway node. This way the 192.168.0.x can
send answer packets to 192.168.2.x when it receives packets from 192.168.2.x
nodes without a NAT between the networks. 192.168.2.x could send to
192.168.0.x because the batman gateway node announced it to batman gateway
clients, but packets in the other direction never found their way because the
batman gateway doesn't announce a backward route to the 192.168.2.x nodes
outside the mesh. This wasn't due to a fault of batmand, but a
misunderstanding what the -a option does and what batmand cannot do (set
routing informations on nodes outside the mesh).

Sven
