Hey guys any recommendation and a good tunnel software for windows? Is there a solution to rdns setup forwarding as well?
It's not worth the time or frustration. If you're really hard pressed to do it, you will need to install openvpn and add some network/routing role which I forget the name of.. Windows servers are not as easily available and come at a higher cost, i would avoid using them for mailing unless you're some kind of self-hating sadist.
