We have a fairly strict policy for only allowing the necessary ports to the necessary IP addresses to/from our corporate network. I need to know the minimum ports to allow in order to permit peer to peer communication between hamachi clients. I also need to know how to configure the hamachi clients.
Based on some information I found in a wiki and other areas, it appears that in order to do this I need to setup static UDP ports and TCP port 12975. Can someone confirm?
It seems that 12975 is used by default by the Hamachi client, so I don't think any special configuration would be needed there. But I am having trouble knowing what part the UDP ports play and how to configure them statically in the client. I found where to configure it (under the Advanced Settings), but I don't know what to put there exactly. Do I just pick a random UDP port? And do I use the same port on all clients in my Hamachi network?
