Hey everyone I have a few routers running an array of firmwares from ddwrt to toastmans latest and last but never least teddys own tomatousb firm. The problem im having is that I can limit tcp and udp on my other routers but it happens that my WRT310N V2 running teddys tomato-K26-1.28.9051MIPSR2-beta22-Mini.trx is not limiting these conns. I have tried various scripts that work for my other routers in different locations but not on this one. Here are some scripts ive tried that work great on my other routers. iptables -t nat -I PREROUTING -p tcp —syn -m iprange —src-range 192.168.1.2-192.168.1.250 -m connlimit —connlimit-above 80 -j DROP this one does nothing at all iptables -I FORWARD -s 192.168.1.2 -p tcp -m connlimit --connlimit-above 40 -j DROP iptables -I FORWARD -s 192.168.1.2 -p tcp -m connlimit --connlimit-above 40 -j LOG --log-prefix "would drop: " for single ips this one sends my router in a reboot loop. iptables -I FORWARD -s 192.168.1.50 -p tcp -m connlimit --connlimit-above 60 -j DROP iptables -I FORWARD -s 192.168.1.51 -p tcp -m connlimit --connlimit-above 60 -j DROP these also send my router into a endless reboot cycle. Note that I always perform full nvram erase before and after flashing so thats not the matter. Any script thrown this way is greatly welcomed.
