Table 31: Filtering of incoming packets

The following part of the conﬁguration form deﬁnes the forwarding policy. If Enabled ﬁlter-

ing of forwarded packets item is not checked, packets are automatically accepted. If this item

is checked and incoming packet is addressed to another network interface, it will go to the

FORWARD chain. In case that the FORWARD chain accepted this packet (there is a rule for

its forwarding), it will be sent out. If the forwarding rule does not exist, packet will be dropped.

Then there is a table for deﬁning the rules. It is possible to allow all trafﬁc within the

selected protocol (rule speciﬁes only protocol) or create stricter rules by specifying items for

source IP address, destination IP address and port.
