i use fedora for my router gateway and few days ago someone stole my bandwidth. look at this log:


stealer ips:
121.43.129.243 <- °Ù¶Èһϣ¬Äã¾ÍÖªµÀ
217.20.127.179 <- Live Search
218.25.163.140 <- 65.49.2.96:443
222.14.174.109 <- http://209.73.169.17/config?
81.22.185.176 <- http://www.clickclickclick.com/clickinf.asp
81.22.185.176 <- Click for United States - Click Click Click - ClickClickClick.com - Click game

my local ips:
192.168.1.156 <- http://www.detik.com/images/detikcom/to-scroll.js
192.168.1.100 <- http://rcm.amazon.com/e/cm?
192.168.1.129 <- http://adimages.detik.com/default/waliiringrev.gif

my question is how to secure my router/gateway from stole activity like that.

thanks
