General info:
The firewall has several sections, for pre-routing, post-routing, input, output and forwarding of data
packets. This refers to the moment of time for the data packets:
PREROUTING:
before effective routing, as soon as the packets are received by an interface.
POSTROUTING
: after the local routing is performed, but before
leaving
an interface
INPUT:
Right before they are sent a local process, the rules apply to external packets that are sent to the
equipment.
OUTPUT:
Right after they are generated by a local process, rules apply to packets that et out of the
BYTTON router.
FORWARD
: transfer operations, the data packets are coming in through one interface and getting out via
another interface.
All these sections may be seen and changed or supplemented in the “Firewall Settings”.
Don’t forget to use the “Save” button at the bottom!
