it was working fine before i created a new instance of my existing instance. when i redeployed the snapshot of both instance onto a another zone, i wasn't able to ping or connect to both instances via lan ip.
one instance is on 10.240.0.5 and another on 10.240.0.6 with 10.240.0.0/16
its on the same network, and i have an existing firewall rules that allow all connection ports between nodes, but for some reason it's not working. so i deleted the existing setting and reenter a new firewall rule default-all-lan
Network default Source IP ranges 10.240.0.0/16 Allowed protocols and ports tcp:1-65535 udp:1-65535 icmp
i still can't ping or connect to any tcp port including web port 80. but when i tried to wget http://node2_externalip from node1, it works! what could be the issue?
