Inbound Rules
Inbound rules can be used to modify the target section of IP packets and, for instance, forward a service
or port to an internal host. By doing so, you can expose that service and make it available from the In-
ternet. You may also establish 1:1 NAT mapping for a single host using additional outbound rules.
Note
The rules are processed by order, that means, traversing the list from top to bottom until a
matching rule is found. If there is no matching rule found, the packet will pass as is.
Description:
A meaningful rule description
Incoming interface:
Interface from which matching packets are received
Source
The source address or network from which matching packets are received.
Map:
Choosing whether the rule applies to the host or to the network.
Target address:
Destination address of matching packets (optional)
Target port(s):
Used UDP/TCP port range of matching packets
Redirect to:
Address to which matching packets will be redirected
Redirect port:
Port to which matching packets will be targeted
Outbound Rules
Outbound rules will modify the source section of IP packets and can be used to establish 1:1 NAT
mappings but also to redirect packets to a specific service.
