Does anyone know of any web-based VPN software I can use to get 'internal' access to web services on my internal network. I use Hamachi normally when away from home however some place (Like work) with the ports blocked Hamachi wont work.

I just want to be able to access web pages on the internal network.

Its a long shot but ideally I am wanting something that will run in IIS. Something that runs on Apache would be OK too but less ideal.

I also use Log Me In for remote access however again this does not work for everywhere (Some places wont let you install the Active X control for it).

I could use VNC, but unless I pay for it its not a very secure option and as this is a kind of stop-gap measure I dont really want to pay for anything.
