Which firewall settings should I use for Geth as a non-miner using Linux Ubuntu 15.10?
Is there a way to check that the firewall settings are correct? If so, how do I check and set the firewall settings in the Terminal?
Should I use ufw and iptables and if so, how?
If someone has a one-liner CLI command for iptables that would be great.
Any official recommendations from core devs or other skilled coders with expertise regarding recommended firewall settings?
These are my current iptables settings. Output from sudo iptables -L
