3.10 NAT settings
In the Network menu, Firewall item,
Traffic Rules
tab you can setup the Traffic Rules, and
the Source NAT settings.
You can add a new rule by the
button and
Save & Apply
to close the upcoming window.
Here you can open ports (e.g. for TCP) for the packages, or define new forwarding rule for interfaces
(New forward rule).
T
he Source NAT settings (below) can be performed for each protocol (tcp, udp), that the router
allows the redirection of data –which incoming IP address and port must be redirected to which
outgoing IP address and port and must be forwarded the data traffic. You also can define a port
range, hereby.
When you modified the settings, save them by the
Save & Apply
button.
These rules must always be defined, not to disallow the general communication.
Take care, because it is easy to enclose the router from the network or disabling the remote access.
Please, be careful when configure these settings.
Important!
Always check the standard ports, which are used by the network services and always allow these
to operating (e.g. FTP: port 21, SSH/Telnet: port 22, web: port 80, DHCP: port 53, NTP time
server: port 123, general network traffic on Windows: 443, etc).
