I'm trying to get the byte counters to work with my nat firewall. However, only a small fraction of all of the traffic is actualy counted. iptables -A FORWARD -o eth0 -d 10.0.0.2 -j ACCEPT iptables -A FORWARD -i eth0 -d 10.0.0.2 -j ACCEPT to try to count both incoming and outgoing data for the 10.0.0.2 host. However when I do iptables -L -n -v -x All I see is 0 transfer, which is quite impossible as I use that host to transfer huge amounts of data.
