Hallo!
My local network is connected to my ISP through DIR-655 (hardware: A4, firmware: 1.30WW). My local computers is connected to this rooter with wired connection. All works fine about one year. Now i have ping packets lost. It's happen'd irregulary. I loose up to 10 packets per time. After that internet connection restores automatically. My ISP ask me to disable all firewalls to chech internet channel quality. I uncheck "Enable SPI" and "Enable anti-spoof checking". However, my ISP cannot reach my by simple ping. Is it possible to route ISP ping or ICMP packets througn router to one of my computers in my side of firewall/router?
In other words: how can i proove my ISP that my local network and rooter works with no errors?
with regards
