If I apply a firewall in DO control panel to/for my droplet, I can no longer ping my Ubuntu droplet/server. Then how can I do basic troubleshooting? How to allow pings thru this firewall?
sudo iptables -A INPUT -p icmp --icmp-type echo-request -j DROP
sudo iptables -A OUTPUT -p icmp --icmp-type echo-reply -j DROP
