I have been trying for days to block one particular IP by using admin/scripts/firewall I am using a RT N16 with a USB 3G connection on 1.28.0000 MIPSR2-095 K26 USB Big-VPN I have tried these following versions that I have found, some on this forum and some from other sources iptables -t nat -A WANPREROUTING -s 220.127.116.11 -j LOGDROP # inbound iptables -t filter -A wanout -d 18.104.22.168 -j LOGDROP # outbound iptables -t nat -A WANPREROUTING -s 22.214.171.124/24 -j LOGDROP # inbound iptables -t filter -A wanout -d 126.96.36.199/24 -j LOGDROP # outbound and iptables -I FORWARD -d 188.8.131.52 -j LOGDROP I put these commands in admin/scripts/firewall - then Save - then Restart. My Log config is set to show blocked connections, its shows the above IP as connected (Accept.) QOS/view details show the IP connected and transferring data. I am puzzled by the fact that the Log shows no Blocked connections what so ever. I have spent days on this googling and reading. I am starting to think something is broken in the IP tables for this build. Thanks EDIT:- Solved - 1 flashed to 1.28.0000 MIPSR2-097 K26 USB Big-VPN - 2 used "iptables -I FORWARD -d 184.108.40.206 -j LOGDROP" in admin/scripts/firewall - restart. (same as previously tried ??) Works a treat, shows as blocked in log.
