Hamachi network connection breaks Retrospect server

Hello,

After installing Hamachi VPN software on my Retrospect server, Retrospect cannot connect with any of its network-based clients. I think that new network connection installed by Hamachi is causing a conflict, but how do I resolve that?

Thanks for your help!

I think I found it myself - you have to do 2 things - make a different connection for your LAN adaptor (to use instead of the default adaptor - which can be done by Configure, Clients, Network-Connection-Button), and then set each client (configure, clients, which-client, and the Access tab) to use that LAN connection instead of default. Then it shouldn't conflict.

Retrospect uses public and private keys for encryption between the Retrospect server and client. Hamachi also uses Public and Private keys and I believe also IPSec. There may be an overlap causing issues. Can you simply un-install Hamachi using Add/remove programs in the control panel, and then restart the server to make sure all services have been re-started ?

Sorry ashembers, didn't see your previous post, as we posted at the same moment.
Sounds like that may work. Other solution, once repaired, is to use a proper hardware VPN based solution. This will not require installation of software or client on the server itself, so there should be no conflict.

Yep - changing the adaptor to LAN Interface for each client fixed it. I think that Retrospect was then wanting to find the client using the Hamachi interface, so that was an easy fix. It' might be useful to know if Retrospect could actually use the Hamachi network, but that is for a whole other topic!
