I am considering replacing my tik with something else because the issues I am having. I wanted to see how these routers were working for others.
Our upstream provider called us complaining about port 25 spam. So created a rule to simply block or filter port 25 on the mikrotik router. Years went on traffic volume has increased. We have been from 100, 250 , 500 and now 1000 mbps fiber. Peak hours we are running at 500 - 700 mbps. I have random dropped packets all over the network. I worked all day today to discover the firewall filter rule was the culprit of my issues. So at the moment I had to disable the port 25 rule. Is anyone else seeing any bottle necks like this. We bought what we thought was a better router the have a CCR model. I was only able to get 150 mbps on the router with the rule enabled now I can max out my pipe with is disabled.
I assume this rule forces every packet on my network through it. Are their other ways to block port 25 that is less CPU intensive?
