To make peer reached from outside, is there any alternative to manually cancelling firewall?
Opened this issue · 4 comments
To make peer reached from outside, the only solution now is manually cancelling firewall of 8090 port. However, in some cases (especially home PCs), only ISP super administrators are privileged to edit firewall settings. Technically, users can use servers or change ISP. But these methods are inconvenient, which may make yacy network weaker.
Another successful P2P network is bittorrent. Users of bittorrent are not required to edit firewall settings. Instead, bittorrent uses NAT hole punching to make peers connected across firewalls.
Concerning yacy network is partially based on senior and principal peers, to make peer reached from outside, is there any alternative to manually cancelling firewall?
There is a workaround using ssh tunneling in a case you have access to some ssh account on a server in public internet.
But, definitely, piercing a firewall in a way bittorrent does would be a huge improvement. Do you have any idea, how BT does that?

I am not familiar with Java, but it looks not THAT difficult:
