Do I need to forward ports explicitely?

Hi,

I am new to Hamachi LogmeIn. I installed on two computers that are not on the same LAN. I created a new network on the web portal, chose Mesh. Then I can connect both to it. Both can ping each other with a 25.* IP address.

Problem:

I am running a server app on one of the computers that is listening for TCP/IP traffic on port 10000.  The second computer just cannot connect.  I disabled firewalls, etc. Seems like the tunnel does not allow this port?  Is there a setting somehwere?

Thanks,

Andy
