Im facing a problem with high upload from wan side, all costumers are disconnected but still have that upload from different ips any idea?
And what you can say about the traffic to us?
Have you checked if you have an open DNS server running on the router. I had a constant upload that I couldn’t figure out where it was coming from, turned out to be thousands of DNS requests.
always firewall the public interface. do you have default configuration, or maybe need help with the firewall?
