I'm new to RouterOS, but i like it.
Today I have one very strange problem:
When i open port 80 or 443 all local internet access stop.
Opened ports work and content. Add a simple web server and Its load from other devices and networks or with mobile data or with VPN, but local internet access stop.
It's very strange because if I'm connected true VPN it's okay i have internet access.
But if i disconnect VPN then i have no internet access.
I open port with this command:
/ip firewall nat add chain=dstnat dst-port=80 action=dst-nat protocol=tcp to-address=192.168.0.74 to-port=80
When i disable this NAT Rule, all its fine and works good.
Some advice where i can search problem or any help. I cant solve this problem 2 days
