Another question about the nodes and how other systems connect to them.
I didn't open port 9333, instead I enabled upnp on my firewall.
When I first fired up the node, the 8 connected clients all appeared to be coming in over 9333. The connection looks like '85.25.134.54:9333    /LitecoinCore:0.17.1/'
The two additional connections appear to be using a different port: '24.50.217.117:53895 - /bitcore:1.1.0-exodus2/' this looks like port 53895 to me,
and this one: '188.131.162.86:47106 - /btc-seeder:0.0001/'  looks like port 47106.
Is this correct? Should I be worried about the connections not on 9333?
