For host and for who join.
And firewall select for to allow game for host and for join.
Nothing other?
A question, before try join is better ping IP host?
I try to day a join and no lucky,but is not possible to have some message or log to understand the reason.
In directory tracking there is a file name net with this
H=0000 RAKNET 0f from 0 Lng=1
Hamachi (hope) bypass these things , the ping for IP host, the ports,the firewall.
Tomorrow i try with Hamachi.
