Hi,

I lost connection when setting up iptables via ssh connection. I tried to reconnect but failed.

Since I haven't got to the step allowing ssh connection, so I guess there is no way that I can access it via ssh anymore. Is there any other methods that I could access the server? I tried to create a new instance with the snapshot but still can't ssh to it.

I was able to solve this problem by myself.

I added "iptables -A INPUT -i lo -j ACCEPT" to VM's startup-script custom-meta(I changed it to "DROP" before losing connection, which was causing the problem).
