Security Policy
Three types of filters can be defined in the firewall:
Port Filters are used to allow or block a specific TCP/IP application level protocol. The
parameters used to specify this filter are source and destination IP address or range of
addresses, a transport level protocol (TCP/UDP/ICMP), and a port or range of ports which
define the application level protocol.
Raw IP Filters are used to allow or block a specific protocol (not TCP/IP) carried within an IP
packet. The parameters used to specify this filter are source and destination IP address or
range of addresses, and a protocol number that identifies the protocol carried in the IP
packet.
Host Validators are used to block all traffic from a specific host. The parameter used to
specify this filter is an IP address or range of addresses.
Note that if invalid filter entries are added, an error message will be displayed when the
configuration is saved.
