You are confused. The 8+0 does not mean this. The difference between the two types of connections are who initiated it: your daemon, or a peer. Data can flow in both directions, regardless of whether it was initiated locally or by a peer. This also means that mining does not need incoming connections. It can work as well with or without. Not allowing ...

To connect to one of moneroworld nodes, one has to establish an outgoing connection. Default firewall policy is to allow outgoing connections and block incomming connections. So you don't need to tweak the firewall to connect to these remote nodes. For your own full node, that would be the opposite. This SE explains how to remotely access your own full node....

If you run a node and do not open inbound connections, then you cannot relay other users transactions or relay blocks. So having a full node in this scenario wont be helping the network. However, it is still useful for yourself, as it increases your security when creating and relaying your own transactions. It's also worth noting that even if you do not ...

MoneroWorld is not dead. Unlikely a ports issue, it's all outbound. You are connecting to it then trying to start_mining and herein lies your issue - you are trying to mine on a remote public node. Please see this Q&A.

No, you do not. You might possibly need open ports if you are "running a node" (i.e., you try to run 'monerod'), and try to mine through that node. If all you want to do is mining, though, I suggest you use a mining pool (see here for a list). In this case you definitely do not need any open incoming ports, since all you need is for your miner to connect ...

Running a node with only outgoing connections is less useful than running a node which allows incoming connections, but still useful. A node which cannot accept incoming connections will connect to nodes from its peer list, and as such is unlikely to find nodes which appeared recently on the network, since those addresses will propagate through the P2P ...

In order to get full wallet functionality, there is no need to allow incoming connections with the local OS firewall. In this mode, you will make 8 outbound connections and 0 inbound connections, be able to listen to all transactions and broadcast transactions to connected peers. I've tested this and everything appears to be working fine.
