Can't Forward port for d-link dsl-2780

[zooploi]

I'm trying to open a port for minecraft but it's not working, I entered the correct number (25565) on Internal startport, Internal endport, External startport, External endport and Protocol Type as it said so but it came up with this:

I don't understand what that means, could you explain it for me please?

I believe it's telling you to use a LAN Ip and not the default gateway of the device. 192.168.1.1 is the default gateway, it's looking for a LAN address.

I can't see what you have typed in for the IP there but it seems think it's the default gateway.
