Why iptraf-ng working just 1 second?

The command below works on my personal notebook, on a Slackware 14.2 VM normally, saving all traffic for 10 minutes; In VM Slackware 14.2, which is a firewall, in the company, the command lasts around 1 second and only registers about four lines of traffic.
iptraf -i eth0 -t 10 -B -L teste.log
