Verifying the Connection Gateway connectivity

Let's assume that the Connection Gateway host is associated with a DNS name, for instance dcv.gateway.domain, and it is listening on TCP port 8443 and UDP port 8443. We can use the nc command to test the connectivity of our gateway.

To check if the Connection Gateway is reacheable with TCP

Use the following command:

$ nc -vz dcv.gateway.domain 8443

To check if the Connection Gateway is reacheable with UDP

Use the following command:

$ nc -uvz dcv.gateway.domain 8443
