UltraHub restrict port forwards to specific inbound ip address

[Brian87788]

I currently have vodafone UltraHub and fibre setup, I have about 2 basic switches in the network with a few computers and printers as well. I am using the 2 phone ports on the UltraHub connected to 2 phones. I am using a cloud based software which I need to open ports for printing to my local printers.

I am continually getting gibberish printing out as I guess hackers are trying to get into the network through those open ports.

How can I restrict those port forwards to only accept traffic from a specific ip address?

Is there a setting on the Ultra Hub or do I need to buy another router/device and install it between the ultra hub and the rest of the network?

Any help would be greatly appreciated.

POS (Point of sale) systems are pretty specialist, and really need a support service.

.@.Jayach Depending on the size and nature of the business the POS may be nothing more than a small card reader, some versions of which do not even need broadband as they support a SIM.

I am guessing it's the OKI toner printers that you got the issue with

Sounds to me like the network is working fine and if it's only the printer you got an issue with then plug it into the router

My printer is plugged into the Vodafone router USB socket and all the devices on my network can print on it fine. 

no need to setup up ports etc as this will make the printer into an internal network printer 

Plug the printer into the USB socket on the router

Log into the router and goes to sharing turn on printer sharing 

Your printer should come up on that page 

its as simple as that 

the sharing page will then tell you your printer address 

On your PC go to add printer I did mine manually 

add printer name and add printer address 

my print address is http://vodafone.broadband:631/printers/hp_photosmart-7700-series_MY4xxxxxxxxx

my printer is a basic 20 years old printer with only has 1 USB cable (no wifi, no Lan, no network) but works fine setup like this. and every device on my network can print on this just fine, makes no difference if your pc etc is  wired, wifi, or network
