As a part of its security features, Textline gives Admins the ability to add specific IP addresses that are allowed to use their Textline account. This is a great feature for those that want to limit Textline access only to their main office and/or force remote users to use the office VPN. This feature is only available to those on the Pro plan.
To set up this feature head to Settings on your navigation bar. Once in settings, click on Security -> Whitelisted IPs to the left.
On the page, you will have options to enable or disable the feature and add IP addresses to the list. BEFORE turning on the feature, make sure to add at least one IP address (preferably the one you are currently using).
To add IP addresses you can use a single IP address: 192.168.1.1 or a comma separated list of IP addresses: 192.168.1.1,192.168.1.2,192.168.1.3 . This list supports IPV4 and IPV6 addresses. For now using ranges (CIDR, asterisk, and colon with subnet) are not supported, so you would need to add each number in the range individually.
