I have a full node on a Gentoo box. I have port forwarding on my router setup so that port 8333 is sent to the IP of my full node. I opened port 8333 on the machine using:
iptables -A INPUT -p TCP --dport 8333 -i wlp4s0 -j ACCEPT
The node is fully synced with the network and I can watch new blocks arrive in the debug log. I thought I was fully participating in the network, but when I check for my full node at Bitnodes it says that my node is unreachable.
Any suggestions? Is there any other way to test public access to my full node?
