All could be little easier, e.g. after installation a quick pop up with info about what ports should be opened... but it works. Ping always depends on the networks... for me it's excellent. Between 50ms and 70ms all the time so not much difference to my "real" ping. Tunngle is totally childish compared to Hamachi.

Hamachi is no longer a viable option for any sort of home purpose. It's done. Go use Tunngle.

Easy setup. Just need access to remote resources (print and file). No need for remote access/control.

Me and my buddy hamachi disguised as an Internet source, and without him ones are using when you want to uninstall it after cleaning the cache you have a big Problem- you must uninstall it from the command line .. I do not recommend it

I used the free gui for this for the longest time, but recently they've decided to phase out this free stuff and make it commercial only. I couldn't use what I had installed anymore as it would only give me an error log and the download for it no longer works either. To top all of that off, the program has always been really really buggy, forcing several of my friends to reinstall this program any time they wanted to use it. They even had to reinstall it every time they restarted their computer. Having just 5 slots per network and yourself taking up one of them was also a horrible limit. I really don't think anyone should get this.

If you really want a good, free, working peer to peer network, get Evolve. It's soooooo much better and basically the same thing.

In light of the recent adverse changes to Hamachi I am looking at alternatives and here are some that I've tried

Wippien: Last update August 2011 This was my favorite because it allows so much customization. None of the other Hamachi alternatives allowed for setting your own IP. Getting this to run as a service was easy with WippienService (another download from the site). There's a caveat though since running as a service causes you to lose the GUI. This means you lose chat and the convenient right click menu. This also doesn't have the network relay feature that Hamachi has when a connection can't be established.

Since yesterday, I have been unable to establish VPN connections with any other computer. Maybe this has become abandonware since it hasn't been updated for over a year. I hope not, because I love it. Edit: it is working again so disregard this last paragraph.

Remobo: Last update August 2012 Very simple to use, but running as a service requires a monthly fee of $7.99 as of writing. For free users, it doesn't have auto login on application launch either so it defeats the purpose for me as I need VPN preferably as soon as I turn on the machine, or at least after login. Otherwise, this has built-in VNC (TightVNC) for remote desktop and a built in proxy server which is interesting.

Comodo Unite (EasyVPN): Last update August 2011 The developers haven't updated this because they are busy working on LoginPro. I've tried LoginPro and it's not a VPN solution. It's more of a remote desktop support solution. Anyway, since this hasn't been updated, the IP subnet is still 5.0.0.0/8. Since this range is now purchased, it is no longer a valid local IP range anymore and will, if not already, conflict with accessing sites/services that use this IP range. Other than that, this can launch as a service and runs stable, even has network relay if a direct connection can't be made. Also it's not limited to 5 users. Once/If they fix the IP range problem, this is the perfect alternative to Hamachi.

Please note: From 19th November 2012, they are "crippling" Hamachi further! - Their "free" version of Hamachi will no longer connect in the background as a service if your computer's powered on, but logged off. Meaning their free version is only suitable for remote access to computers that are permanently logged on!

Another very bad move from LogMeIn as they continue to "cripple" what was once a great service!! :(
