This feature allows to block specific ports for TCP/UDP connection. It is also possible to add specific IPs
or subnet as a whitelisted so that the rule for the port will not work.
NOTE : Imunify360 can block particular ports using this feature, yet it doesn't support a paradigm to
"block everything but the selected ports". That could be achieved via legacy linux iptables.
Click Firewall and choose Blocked Ports.
Use filters to show the exact list of the IPs:
- IP – allows filtering the list by IP. Enter an IP or a part of it into the input field.
- Country – allows filtering the list by country origin. Enter a country name into the input field with autocomplete. Imunify360 will show the list of IPs of the chosen country.
- Comments – allows filtering the list by comments. Enter a comment into the input field.
- Use Items per page at the page bottom right to set the number of the incidents to be shown on the page.
The following actions are available for the ports:
- add port to the list of blocked ports
- edit ports in the list of blocked ports
- add a comment
- delete permanently
#Add a port to the list of blocked ports
On the Firewall page choose Blocked ports and click Add. In the pop-up specify the following:
- Port – the number of the port to be added to the list of blocked ports.
- TCP/UDP – tick the checkboxes of connection types for the port that should be blocked.
- Enter comment (optional) – a text to be added as a note for the port.
- Whitelisted IPs – add IPs separated by comma to the White List. They will be able to use the port.
Click Add Port to proceed or Cancel to close the pop-up.
Edit ports in the blocked ports list
To add an IP or a subnet to the White List for the port, click +IP and in the Add IP/Subnet pop-up specify the following:
- Enter IP – IP or subnet that should be added to the whitelist
- Enter description – a description to be added as a note to the IP or subnet.
Add a comment
In the proper port row click in the Note column, type a comment and click .
To remove a comment, click and remove the text. Then click .
To delete a port or separate IP/subnet, click Bin icon in the row of the element.
