Mikrotik rb951-2n not opening forwarded port from LAN?

Question

Mikrotik

Good day to all. set up a router, made port forwarding, the site opens from the external network and there is a connection via rdp but from the local network if you open the site via a domain name. it throws an error. tell me how to fix this problem?

Answer 1

A thousand times solved problem. Hairpin-NAT you need either a replacement DNS name for local users or DMZ with full routing and no port forwarding.

it's not entirely clear what needs to be done in order to solve the problem

Answer 3

add another rule to NAT:
the link has an example
/ip firewall nat
add chain=srcnat src-address=192.168.1.0/24 \
dst-address=192.168.1.2 protocol=tcp dst-port=80 \
out-interface=LAN action=masquerade
