Just tried Hamachi and it's quite neat.
I had a bit of a mare installing it but I think that was a problem at my end. The install hung and I had to manually uninstall the network driver and hack out the registry entries before it would let me reinstall. It's okay now. But I haven't heard any horror stories about it on here so I do think it was just a glitch at this end. I installed it on a second machine and it went on fine.
Configuration is fairly straightforward. Is it any easier than setting up a port forward? No, not for me, but then I know what I'm doing with my router. But at least if you go down the hamachi route then as the support person
there is only one set of instructions to work with.
The current licensing is free for non-commercial use. The link from the pinned post on the Troubleshooting forum isn't to the latest version. It's to an earlier one which I think
was on a different license - so I'm not sure if the "old" link is deliberate.
However hamachi performs very poorly over my (admittedly very naff 0.5 Mb) broadband connection. Considering I've effectively only got half of that because both of the hamachi test machines are this side of the router it's hardly surprising. However at least TeamViewer VPN worked after a fashion - hamachi continually drops the connection.
Radmin aside I actually really like hamachi as a product. You can set up your own multiple VLANs and you have a lot of control over access, network groups and configuration. So I'm definitely going to hang on to it just for the VPN.
One neat feature of hamachi relating to earlier posts on this thread is that you can turn off encryption on a per VLAN basis. I tried doing this and although I think performance was improved, it still wasn't enough to allow hamachi to maintain the connection.
So as a VPN for Radmin use then TeamViewer VPN (also free for non-commercial) has the edge for me, but that's only because of my naff connection.
But as a product hamachi wins easily from what I've seen, and for most people I'm sure it's just fine for Radmin use. But as you say, it's one more potentially unnecessary thing to have to worry about.
Bottom line then - I'd still like to see a lightweight VPN built into Radmin!
