Port definition as forwarding

Destination
port number does not change

Single ports
or

Port Ranges
2.
Source
port number as forwarding criterion: If the source port number is to
decide to which IP the forwarding is to be made, this is marked with a leading
character before the port number.

Single ports
or
Port definition as redirection

You can create up to 30 of these rules.
In a rule definition, both port ranges and multiple port redirections can be defined by
specifying them separated by commas. For example, you can use the rule:
TCP:3000-3010,4001,4004,5005:192.168.1.2
that all data for ports 3000 to 3010 + 4001 + 4004 + 5005 are forwarded to IP ad
-
dress 192.168.1.2. It is not possible to redirect from one port range to another. To
specify the source port number as a criterion for assigning an IP address, you can
specify the port number with a leading
character.
On the LAN side, a DHCP server can be activated to provide the LAN clients with IP
addresses. The distribution of IP addresses can be specified using a reservation list
based on the MAC address of the LAN client or the device name.
