Yep

WiFi to WiFi is contained onto your Local Area Network (LAN) which is private.
Your 3G goes off site (wireless company) and back in on however the laptop connects via the WAN (Wide Area Network) Which is PUBLIC. When you do this, you need to grant access (sometimes refer to as a port pin hole). There are a ton of security issues that need attention when you do this (not done casually and stay secure)
