For a secure connection, you need to create a VPN connection from your home network to your office network.
Here’s a list of a few ways you can do this:
- Setup an IPsec tunnel on your firewall
- Use a Router to Router VPN from your office to your home
- Install an SSL VPN or VPN concentrator
You can use Attachmate Reflection for the Web as another solution so you don’t need to have client access installed.
