Title: PING-FLOODING ATTACK FROM WAN/LAN
Post by: eenguz on January 05, 2015, 12:16:25 AM
hello, so just yesterday my latency suddenly went unusually high and i decided to check my router's log if it was able to trace where the traffic was coming from and to my surprise my log was filled with these

both from LAN and WAN. this 192.168.0.103 that was detected is my iphone and i have clearly no idea how my phone could ping attack my own network.

Internet Service Provider and Modem Configurations

The logs are indicating what the router is designed to do, let you now of what the firewall is capturing and blocking. I recommend you phone contact your ISP provider and ask them to check your modem, signal and any unusual activity on your line. Ask them to change the WAN IP address.

What ISP Modem service link speeds UP and Down do you have? normally, my dl speed is at 3mbps, ul speed at 0.8mbps and ping is 31 (according to speedtest), but ever since those ping flood attacks started coming my dl & upload speeds have been fluctuating and my ping(which im very concerned about) stays at 140 ms
