Hello friends, I have a problem that arose a week ago, I have a wan network, which through the firewall has a referral to an IP and port of my local network which exposes a web page to the outside, it works well but every so often time the domain stops responding. When you restart the mikrotik it works again until it crashes again, the infrastructure has worked like this for approximately 2 years without previously presenting this problem, does anyone have an idea what it could be?
