Why am I unreachable?

Question

I'm certain the forwarded port of 18081, 18089, 18080 are forwarded to the machine and i've completely disabled windows firewall. Is this my ISP blocking this port?

If you read your logs:

W --public-node is enabled, but RPC server 127.0.0.1:18081 may be unreachable from outside, please check RPC server bind address

Then check the monerod --help output:

--rpc-bind-ip arg (=127.0.0.1)             Specify IP to bind RPC server
--rpc-restricted-bind-ip arg (=127.0.0.1)  Specify IP to bind restricted RPC server
--confirm-external-bind                    Confirm rpc-bind-ip value is NOT a loopback (local) IP

So to bind all interfaces (which includes external), use 0.0.0.0 instead of 127.0.0.1, and use --confirm-external-bind to state you know what you're doing.
