Hello,
I’m having a problem with RB5009UG+S+IN. Till two days ago, router was working as a charm, and than without and change on it, ping stopped working.
I have tried to ping that router from several devices, but no luck. When I check firewall connection list, there is ICMP, but routers from which I ping it getting timeout.
I tried do disable all firewalls that I have, a filters, but no luck.
Only time when I get some ping is when router is turning on or shutting down, 3-5 pings.
ROS that I was tried to use was from 7.6 to latest 7.10, but still no luck.
