Yes, RelayNodeClient.jar is nice.

Add node option can be checked with=>


which gives IP=>
public.us-east.relay.mattcorallo.com has address 162.243.69.180

then,

Should give established connection between local IP and 162.243.69.180

To check actual traffic between local node and 162.243.69.180 tcpdump can be used.

Change MyNetworkInterface respectively with your network interface.

0 packet captured means something is wrong, else should be fine.

Cheers,
