Re: openssh only accepting local network connections
When you're accessing the servers from "not the local network", is this over the internet? Via a VPN? Or do both boxes have public IPs?
What's the error you get when you try? Try the verbose setting as TheFu asked.
If the boxes have private IPs, some sort of NAT or port forwarding needs to happen to get to them from outside unless you're VPNed in.
It could also be a firewall not allowing access to the new box from outside, even if the IPs are public.
You said you also opened 80 and 443, is there a webserver on the box you can try accessing? If you can't get to that either, it's probably a firewall in between needing to be configured.
