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?
I believe you’re talking about other users’ connections who use different port numbers. In that case, no worries.
There are nodes who use all sort of devices and port numbers to connect to other nodes. Like you yourself, there are many people who run multiple nodes using 1 public IP so they must manually open up different ports.
