I am using UBUNTU system, my ec2 instance is working fine, I can ssh to it with my mobile phone network. But when I use my home wifi, I cannot access.
When I type:
ssh -i x.perm user@xx.xx.xx.xx
it just hangs there, even ctrl+c cannot force to recover.
I've checked my router settings, the settings should be fine. I don't need to use port mapping, as I assess to ssh server outside my router.
Any idea I can access my ec2 instance?
