I try to access my external IP address from the local network, but instead of reaching my webserver behind NAT - the webfig page shows up.
NAT forwarding is working when accessing from the internet.
EDIT: This is my current nat config
[admin@MikroTik] > ip firewall nat print
Flags: X - disabled, I - invalid, D - dynamic
