8.2 Hide NAT
Private IP-addresses are not routed in the internet. Therefore outgoing packets must get the
external IP of the firewall. The function Hide Nat realites this.
The
Source
is the network or the computer, which IP will be replaced by the Hide NAT.
Behind IP / Interface
describes which IP-address the packets get instead of their own one.
You can define an IP-address or an interface. If you use a dynamic IP, insert the DSL inter-
face.
The
Destination
must be set to declare, in which case the Hide NAT is to be used.
Network objects are used for source and destination. To create Hide NAT rules, you maybe
have to create network objects before.
The option
Include
means that the Hide NAT will be used. The
Exclude
option means that
the Hide NAT will not be used and so packets will be send with their original IP-address (for
example in tunnel connections
– IPSec, site-to-site).
