3.4.4.6 IP Forwardings
gateprotect Firewall supports "IP Forwardings" , which can be used to publish services
provided by an internal server to the Internet without assigning a public IP address to
this server. The server's internal IP address is transparently mapped to a public IP
address.
IP forwarding rules redirect all incoming traffic for the WAN zone's public IP address to
an internal IP address.
For IP forwarding, NAT must be enabled in the WAN zone settings. For further infor-
mation, see "WAN Zone Settings" on page 85.
IP forwarding can only work if the WAN IP address is configured as a static IP address
(no DHCP/PPPoE). For further information, see "Multi-WAN Settings" on page 86.
IP Forwarding Overview
Navigate to "WAN > IP Forwardings" to display the list of IP forwarding rules that are
currently defined on the system in the item list bar.
In the expanded view, the columns of the table display the "Name" and the "State"
(active or not) of the IP forwarding rule. The buttons in the last column allow you to
view and adjust the settings for an existing IP forwarding rule, create a rule based on a
copy of an existing IP forwarding rule or delete a rule from the system.
