Hamachi gateway on raspberry

Hello to everybody.

Here I try to describe my scenario with my issue.

I've installed hamachi on my raspberry pi and I was able to create my VPN with my gateway-raspberry_pi.
I am also able to connect to my gateway-raspberry by remote session using ftp and ssh.
Now here what I get:

1. if I use ADSL internet connection for my raspberry_pi-gateway I am able to access to my entire LAN by remote
2. if I use a mobile 3G connection for my my raspberry_pi-gateway I am NOT able to access to my entire LAN by remote. In fact, in this case I am ONLY able to conenct to my raspberry_pi-gateway using only ssh and ftp.

Can you help me on that? How can I solve this issue? Can it be that the mobile ISP blocks some ports?

Thanks in advance,

Peppe.
