How to create single ip address to map to different internal ip address on sonicwall

moyusuf001

Is there a way to use single public IP address and forward the same ports to 6 devices on NSA4600?

We have 6 systems and use port 22, 5001,21 from outside to connect internal system or devices.

I need to configure port group for example

IP Address Ports Internal IPs

56.56.56.45 22,5001,21 1.1.1.1

56.56.56.45 22,5001,21 2.2.2.2

56.56.56.45 22,5001,21 3.3.3.3

56.56.56.45 22,5001,21 4.4.4.4

56.56.56.45 22,5001,21 5.5.5.5

56.56.56.45 22,5001,21 6.6.6.6

I am not sure how to achieve when someone connects to one of the device using SSH? Can please someone help me?

Thanks,

@moyusuf001 the answer is no, you cannot share the same public ip and port to multiple internal IPs, because there is no way to distinct what internal system should be connected to. I suggest having different ports if public IPs are limited.

Another option would be some kind of proxy which accepts the inbound connection and routes it to the destination, if SNI or similar is possible, depends on the protocol/application.
