connect 2 nodes which are global

Question

For e.g. One node is in NYC and other in Boston, what can I do to connect

I followed https://www.multichain.com/getting-started/ which helps me connect 2 nodes on same network

But if I try to connect nodes which are not in same network, than it shows me an error

    

Output:
MultiChain 1.0.2 Daemon (latest protocol 10009)

Retrieving blockchain parameters from the seed node 192.168.56.1:2693 ...
Error: Couldn't connect to the seed node 192.168.56.1 on port 2693 - please check multichaind is running at that address and that your firewall settings allow incoming connections.

Answer 1

The issue is probably exactly as written in the error message. You need to open port 2693 to external incoming connections using the system firewall software (e.g. iptables on Linux) or an external firewall if appropriate.
