Can the standard SMTP/DNS/SSH/... port be forwarded on a Nginx Accelerated Share

Basically, we've seen this VPS used as a remote monitoring system, root-level shell account, accelerated webserver, more secure database server, etc...

With Nginx Accelerated Shared IP, you're getting a VPS that resides on a NATed network. This enables not only an inherent firewall, as the actual VPS would be assigned a private NATed IP address, you also gain:

1) HTTP acceleration via a powerful Nginx accelerator.
2) Lower month-to-month costs per VPS.
3) Better secured database server; does a database server really NEED a public IP, if its only supporting a webserver on another VPS?
4) Inexpensive remote node for Nagios and other systems monitoring solutions.
etc...

As for accessing it. You normally connect to TCP port 22 when making an SSH connection. Your SSH/Administration connection would instead be to, for example, port 45001 (easily accomplished via any modern SSH tool).

If you'd like to enable something to connect directly from the internet to the NATed VPS, and its not something we can pass through the HTTP Nginx accelerator, then each VPS includes the option to port-forward up to 100 distinct non-standard service ports from the shared IP to your VPSes. Port-fowarding requests are serviced on a first-come first-served basis; if someone requests a range of ports that you'd also like, we assign them to the inital requester first, we'd then evaluate if your VPS could be migrated to another server to meet your request.

In-all, with any configuration combination, for just $1/month more you can always order a dedicated IP.
