Network Firewall

Slicie allows for inbound and outbound firewall rules for both IPv4 and IPv6 traffic.

TLDR: Port and IP Format

You can specify an entire subnet like this: 192.168.12.0/24

You can specify an IP range like this: 2000:2100, which includes 2100.

You can specify multiple items by seperating them with commas, like this: 192.168.12.1, 192.168.12.2. Whitespace is ignored.

What can I use the firewall with?

The network firewall is available for Cloud Servers. We don't provide a configurable firewall for cPanel accounts, because we manage the firewall on shared hosting servers ourselves.

Where can I configure the network firewall?

Start by viewing a server's overview.

On a high resolution desktop, you can click "Connect" in the top navigation. Within the drop-down menu, you can select an existing firewall or create a new one. You can also edit the firewall using the navigation on the left, below your server's name.

On lower resolution displays, there is a section at the top of the page dedicated to showing your firewall.

How it works: Network Access

IP traffic to Trusted Networks always pass through the firewall. IP traffic to Banned Networks never pass through the firewall. This applies to both inbound and outbound traffic.

You can provide individual IPs, like 192.168.0.15 and 2001:0db8:85a3:0000:0000:8a2e:0370:7334, or subnets in CIDR notation like 192.168.0.0/24 and 2001:0db8:85a3::/64

What this setting means: Allow All

All of this type of traffic is passed through the firewall. For instance, a setting of "Allow All" for outbound UDP traffic means that the firewall will never block outbound UDP traffic.

What this setting means: Deny All

All of this type of traffic is blocked by the firewall. For instance, a setting of "Deny All" for outbound UDP traffic means that the firewall will never allow outbound UDP traffic.

What this setting means: Allow Custom

Only the ports you provide will be allowed. Every other port will be blocked.

You can provide multiple ports by using commas. For instance, if you wanted to allow only web traffic, you could provide this: 80,443

What this setting means: Deny Custom

Only the ports you provide will be blocked. Every other port will be allowed.

You can provide multiple ports by using commas. For instance, if you wanted to block only web traffic, you could provide this: 80,443

How it works: Specifying multiple ports

You can specify an inclusive range of ports like this: 1000:2000

This refers to port 1000 and port 2000, and every port in between.

How it works: IPv4 and IPv6 Pings

You can choose whether or not allow or block pings to your server. You can choose "Accept" to allow pings, and "drop" to block them.
