Identifying how remote systems connect to Cloverleaf (VPN)

[Carson Nguyen]

Our organization is underway in migrating from existing Cloverleaf Production server to a new physical server.  We have requested from our Networking team a list of all VPN configurations to identify which systems/interfaces are impacted.  It was easy to identify the outbound connections using a public IP address.

However, we have not found a clear way to identify connections to our Cloverleaf from a public IP address (to determine if the inbound connection is utilizing VPN).

We would like to see how everyone else has handled this with prior server migrations.   Thanks in advance.

We document within the Notes of the thread here.  However, you could probably look at all the current production connections that you have and map them via port number to a netstat -an (AIX command, but should be similar in Windows) and look at the IPs that are connecting to each of your threads.  Of course the more threads you have, more tedious this is, and identify those IPs not within your organizational subnet(s).  After that, I’d document those that are coming from outside in the Notes section of the NetConfig.

Hope this helps,
