Creating IP Address Block Lists

When you block an IP address, individuals from that IP address are prevented from logging in, even if their other credentials are correct. Blocking IP addresses is done at the corporate account level–an IP address that is blocked is blocked for the corporate account.

To block an IP address or range, you add the IP addresses/range to a Block list, then enable the Block list.

To configure a Block list

1. In Barracuda XDR Dashboard, click Setup > IP Blocking.
2. In Account, in the top navigation bar, ensure your corporate account is selected.
3. In the Block List section, in Choose list, select a list.
4. Click Configure.
5. Type a new name.
6. Select the block lists to include.
7. Click Save.

For the addresses in the Block list to be blocked, you must enable the Block list.

To add an IP address or range of IP addresses to a Block list

1. In Barracuda XDR Dashboard, click Setup > IP Blocking.
2. In Account, in the top navigation bar, ensure your corporate account is selected.
3. In the Block List  Items section, click Add Item.
4. Select the list you want to add the item to.
5. Type one or more of the following:
   • An IP address

   • A range of IP addresses

     You can use IPv4 and IPv6 notation.

     Separate IP addresses or ranges with a comma.

6. Optionally, type a comment.
7. Click Save.

For the addresses in the Block list to be blocked, you must enable the Block list.
