Your export has this one multiple times:
add action=dst-nat chain=dstnat dst-address-list=WAN-IP dst-port=25565-25620 \
protocol=tcp to-addresses=192.168.2.141
if that’s not the case check your export again and post a new config
Also on your screenshot your NAT rules have 0B Transferred. You sure theyre working?
nvm i didnt read that far while playing a game ^^
EDIT: also that “hairpin nat” rule is never gonna work. As you never actually access the server with the 2.141 IP if you’re using your WAN-Address
You must use your wan IP as dst-address.
