Hub 3 OUTBOUND port block single port
I see there was a previous post on this same subject that wound up getting a bit heated so I'd like to start a fresh discussion.
The Superhub 2ac used to have the option for port blocking ( I have a screen dump of it for those who don't believe me ). It was possible to create and name a rule that blocked a port range or a single port for TCP/UTP for a given IP address. So in my case I assigned a fixed IP address via the device's MAC address I wanted to block and created a rule to block port 5678 for TCP & UTP for IP address 192.168.0.21
The newer Hub 3 which I have been supplied with when the hub 2ac failed has no Port Blocking option in the router interface.
I have looked in detail at the Advanced/Security settings and the only option that looks like a possibility is the "IP and Port filtering" option. So I would like some help to understand if this would do the job.
The heading for IP and Port filtering says "This section allows you to specify packet filtering rules to limit internet access for local hosts". I take this to mean it can block packets from getting out onto the internet if they meet the rule.
The rule creation has the following parameters:
Enable/Disable, Protocol, Source IP address, Destination IP address, Source port range and Destination port range
So if I create a rule that has the following
ENABLE, Protocol- UDP/TCP, Source IP - Single 192.168.0.21, Destination IP - ALL
Source port - 5678 to 5678, Destination port - 5678 - 5678
Would this FILTER OUT (i.e. discard) any packets that meet this rule from the outbound path to the internet ??
OR am I barking up the wrong proverbial tree ?
I know I can buy my own router and put the Hub 3 into modem mode but why should I have to fork out for a router and have two pieces of kit running up my electricity bill solely due to Virgin downgrading my router ?
