Turns out I didn't have the batgat kernel module loaded; now I can connect to the net. However, the default gw is still not automatically set on the repeater

Hi, new at batman. I've got the following done:

1. got an airlink ar430w and wrt54gl to ping each other over ad-hoc network
2. setup br-lan:0 on each router. ar430w has is 192.168.100.1;

wrt54gl is 192.168.100.2 3. was able to ping each other via br-lan:0 IP 4. using openwrt 8.09 on both routers.

The wrt54gl got the wan/internet link up. I started "batmand -g 1mbit/128kbit br-lan:0" the ar430w doesn't have internet; I started "batmand -r 3 -d 3 br-lan:0"

got this on the ar430w logs:

Interface activated: br-lan:0 Using interface br-lan:0 with address 192.168.100.1 and broadcast address 192.168.100.255 B.A.T.M.A.N. 0.3.1 rv1206 (compatibility version 5) Adding throw route to 127.0.0.0/8 via 0.0.0.0 (table 68 - lo) Adding throw route to 192.168.1.0/24 via 0.0.0.0 (table 68 - br-lan) Adding throw route to 192.168.100.0/24 via 0.0.0.0 (table 68 - br-lan:0) debug level: 3 routing class: 3 Adding route to 192.168.100.2 via 0.0.0.0 (table 66 - br-lan:0) Found new gateway 192.168.100.2 -> class: 32 - 1024KBit/128KBit Adding default route to 192.168.100.2 (gw_flags: 32, tq: 217, gw_product: 0) Gateway client - got IP (169.254.0.1) from gateway: 192.168.100.2 Adding default route via gate0 (table 68)

When I run route -n on the ar430w, there's no default route set. I manually ran: route add default gw 169.254.0.1

Next I tried to ping the outside world on the ar430w but it gets no where. Any ideas?

thx mike

Hi,

Gateway client - got IP (169.254.0.1) from gateway: 192.168.100.2 Adding default route via gate0 (table 68)

When I run route -n on the ar430w, there's no default route set. I manually ran: route add default gw 169.254.0.1

so far everything is correct but the deprecated "route -n" command shows you only one routing table. As the log indicates the default route went into table 68. You can see it using:

ip route ls table 68

More information regarding the routing tables can be found here: http://www.open-mesh.net/wiki/RoutingVodoo

Next I tried to ping the outside world on the ar430w but it gets no where. Any ideas?

You need to NAT on your gateways (wrt54gl) internet interface. iptables -t nat -I POSTROUTING -o $your_wan_if -j MASQUERADE

Depending on the batman version you use it might be required to NAT on the gate0 interface on the client side in a similar fashion. With batman version 0.3.2 its not necessary anymore.
