I am getting a warning: You cannot be reached from outside. A possible reason is that you are behind a firewall, NAT or Router. But you can search the internet using the other peers’ global index on your own search page. We encourage you to open your firewall for the port you configured (usually: 8090), or to set up a ‘virtual server’ in your router settings (often called DMZ). Please be fair, contribute your own index to the global index.
However, I am reaching it from the outside on https://yacy.eskimo.com/ from my Comcast cable modem and it is indexing just fine so it is also able to get out. I have it proxied through Apache so it can not be reached directly on port 8090 or 8443 but that is by intent.
Not clear why it thinks this is an issue.
