No internet #29

I'm using this software on a router with OpenWRT but I can't log the traffice to/from the internet. This is my configuration:

config nlbwmon option commit_interval '24h' option refresh_interval '30s' option database_directory '/var/lib/nlbwmon' option database_generations '10' option database_interval '1' option database_limit '10000' option protocol_database '/usr/share/nlbwmon/protocols' list local_network '0.0.0.0/0' list local_network 'bridge'

eth0 and eth1 are configured with a DHCP bridge. Do I have to specify individual interfaces or do I need to specify the bridge?

The local_network must correspond to the IP address range used on your lan, e.g. 192.168.1.0/24 since it is used to differentiate incoming and outgoing request. With 0.0.0.0/0, any traffic will be treated as local to local and will not get counted.

Thanks for your quick response

Okay, I set 192.168.0.0/16 as a subnet but I still don't see the traffic to the internet, only the local one. Am I doing something wrong or is nlbwmon not the software that does it for me?

I'm looking for a software that logs me traffic and ip addresses in forwarding on the router and I was advised this for its clearly better performance than iptables log

I am not sure what you expect to see but this software will count and aggregate outbound traffic per lan host. Maybe this is not what you're looking for.
