Setting a YaCy peer

I’m having trouble setting up my machine as a YaCy peer.

I’ve opened port 8090 on my firewall:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:8090

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:8090

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:8090

I’ve also forwarded the port in my router:

Still, the network cannot reach my peer.

Also, it would be nice if YaCy hosted an IRC or Matrix channel.
